If you are adding a bank of switches or four outlets in one spot, the box behind them is the part that decides whether the job feels easy or fights you all afternoon. The biggest split is between new-work boxes, which nail onto an exposed stud before drywall goes up, and old-work boxes, which clamp into a hole in a finished wall. Get that one call right and everything after it is straightforward.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Capacity, material, and mounting style are what separate a box you install once from one you curse twice, and the right pick changes completely depending on whether your walls are open or finished. Below you will find the strongest options for a best 4 outlet box.
Our Picks at a Glance
How To Choose The Best 4 Outlet Box
Four devices in one housing is a lot of copper to fold into a small cavity, so the box you pick has to solve two problems at once: it has to hold everything without pinching, and it has to mount to whatever wall you are actually standing in front of. Here is what to weigh before you order.
New work or old work
New-work boxes carry captive nails on the side and get driven into a stud while the wall is still open — the box is fastened before drywall goes over it. Old-work boxes go in the opposite direction: you cut the opening in a finished wall, then metal or plastic wings clamp the box against the back of the drywall from the inside. Buying the wrong one means a return and a stalled job, so measure your situation first. If the drywall is already up and painted, you want an old-work or recessed design. If you can still see bare studs, a nailed new-work box is faster and cheaper.
Capacity in cubic inches
Capacity is the number that decides whether the install feels roomy or cramped. A four-gang box has to swallow four devices plus the wire that feeds through to the next location, and the published interior volume is your guide. Two boxes on this list both advertise 60 cubic inches, while one deeper old-work model offers 71 cubic inches and a metal square box offers 21 cubic inches at 1-1/2 inch depth. More room usually means easier folding, less strain on the device terminals, and a shorter wrestling match when you push the devices home.
Material and where the box lives
Non-metallic PVC boxes are lighter, do not rust, and their plastic construction is designed for easier installation with non-metallic sheathed cable. Drawn steel boxes form the body as one piece so there are no welded seams, and a metal enclosure with a raised cover is what you would choose for exposed work on a block wall or a surface-mounted conduit run where grounding continuity matters. Neither is “better” on its own — match the material to whether the box is buried in drywall or sitting out in the open.

In‑Depth Reviews
1. 4-Gang PVC New Work Switch/Outlet Wall Electrical Box, 60 cu in
Our pick — over 4.5★ from 350+ verified ratings; the strongest balance of quality and price.
Four gangs of room with nails already on the side, ready for open studs.
This is the box you nail to a bare stud before the drywall goes up, and it arrives in a three-pack so a whole wall of switch banks gets handled in one order. It carries ETL certification (an independent safety listing that confirms the box was tested to electrical standards) and is rated for 2 hours of fire resistance. Its published interior volume is 60 cubic inches, and the box measures 7-1/2 inches long by 3-2/3 inches wide by 2-3/4 inches deep. It weighs 16 ounces, so it holds its position on the stud solidly while you work. The nails are already attached to the side, which is the part that saves you the most time on a rough-in.
The 4-Gang PVC box here is also meaningfully lighter than the Carlon B468R at 8.16 ounces, a real difference when you are holding one against a stud with one hand while you swing a hammer with the other. On capacity it gives up ground to that same Carlon, though — 60 cubic inches against 71 cubic inches, so any job with several circuits passing through will feel tighter in this box. Wire count is generous for a 60-inch cavity: the maker rates it for 30 14-gauge conductors, 26 12-gauge, or 24 10-gauge wires. That matters because four switches plus a feed-through circuit is exactly the crowded scenario where a small box turns into a fight.
What wins people over is the build — quality is the trait owners praise most, with functionality right behind it, and the same ones you would find at the big box stores is how buyers describe them. It takes four switches or four outlets, so it covers both residential and commercial layouts. Two things to know going in: not every install is smooth, because the recurring note is that screw holes can run tight, and it is a new-work box, so a finished wall is the wrong application for it. Buyers report: “Work great and easy to install. Same ones you’d find at the big box stores.”
What Earns Its Keep
- Three boxes per pack at a mid-range price, so a whole rough-in is covered in one order
- Nails pre-attached to the side — the fastest way to fasten a new-work box to a stud
- ETL certification plus a 2-hour fire-resistance rating
- 60 cubic inches and published wire counts up to 30 conductors in 14-gauge
Where It Gets Tight
- Screw holes can be snug, so start the screws by hand before you reach for a driver
- New-work only — the nails make it useless on a finished wall
- Less interior room than the 71-cubic-inch Carlon if you are folding in a lot of cable
Buy this one when: your studs are still visible and you want the box nailed, listed, and out of the way without a second thought.
Pass on it when: the drywall is already hung and painted — you need an old-work box for that wall, not nails.
2. Carlon B468R Work Outlet Box, 4 Gang, 7.57-Inch Length by 2.89-Inch Width by 3.56-Inch Depth, Blue
The deep retrofit box that swallows four circuits when a finished wall has nowhere to put them.
Cut the hole, fold the wings back, tighten — that is the whole install, and it is why the B468R is the one to reach for when the drywall is already up. PVC construction is intended for easier installation with non-metallic sheathed cable, and the box is explicitly designed and listed for that cable type under the wiring code, with all PVC boxes permissible for 90 Degree C connectors. It also weighs in at 8.16 ounces — roughly half the heft of the nailed box above. The 4-gang footprint measures 7.57 inches by 2.89 inches by 3.56 inches deep.
Depth is the number that earns its reputation here. Wiring one setup that replaced a 3-gang with four switched circuits plus a feed-through leaving only 71 cubic inches of room to work with, the extra depth was the difference between a clean fold and a jumble. That same box gets reused in media installations specifically for how readily it seats into almost any wall opening. Kitchen and workshop jobs land on it too — homeowners have swapped tired single rocker plates for a four-gang cover, added a night light with its own switch, and been pleased with how it sits by the sink. Under a bench or behind a rack, it handles two 20-amp circuits more tidily than a row of bench strips.
Sturdiness is the other thing buyers single out: it reads as heavier-grade than the flimsier boxes sold around it, and the finish work looks tidy next to a countertop. The catch is the plastic drywall tabs. Plastic drywall tabs are the part that breaks on these old-work boxes, and it breaks from installer technique rather than a defect. Run the screws in and out once before final tightening, keep them snug rather than gorilla-tight, and the tabs will not fight you. Skip this and the tab is the first thing to give.
The retrofit answer: if the wall is closed and you need four devices in one cut, the 71 cubic inches and screw-in wings make this the most forgiving box in the group.
The tab is the tell: plastic old-work tabs tolerate finesse, not force, so snug the screws and stop.
Made for: finished-wall retrofits where you are cutting new openings and want the most elbow room to fold wire.
Wrong tool if: the studs are still open — a nailed new-work box installs faster and costs less.
3. 4-Gang PVC New Work Electrical Box, 60 cu. in. ETL Listed(1Pack)
A single new-work box built to hold thirty 14-gauge conductors without complaint.
If your four-gang location also carries a feed-through circuit or two, this is the new-work box to beat, because its wire capacity is stated in plain numbers you can plan around. The 60-cubic-inch interior holds up to 30 14-gauge wires, 26 12-gauge wires, or 24 10-gauge wires. It arrives with fixed nails for stud mounting and live hinges that swing open to take the sheathed cable, then close back over it. ETL certification puts it in line with national electrical specifications, and the shell is PVC rated waterproof and dust proof. Weight is 195 grams, so it is light enough to hold in place with one hand while you drive the nails.
New construction is where it earns its keep. It handles a bare-stud rough-in the way the Carlon handles a retrofit — different job, same idea of giving the wire somewhere to go. The living hinges are the detail that separates it from a plain nailed box: they hold the cable as it enters, so you are not fighting a loose sheath while you try to fasten the box straight. The open rectangle shape and stated depth of 69.7mm keep the interior clear for devices.
Quality is what buyers talk about first, followed by functionality, and the takeaway reads the same way each time — a box that comes out of the bag looking well made, with nails that feel solid and wire flaps that are firm without being stubborn. The one wobble to know about is the nail bracket: a bracket separating from the box is the failure mode to watch for, so give the nails a firm, square drive rather than a glancing blow. It is a one-pack, so a four-gang wall plus spares means ordering more than one. Reach for this if new construction and heavy conductor counts are both on your list.
Count first: 30 conductors in 14-gauge is the number that makes this the right box for busy four-gang runs.
Drive square: the nail bracket is the weak point, so hit it straight and firm.
Suits: opened-up walls where multiple circuits meet at one four-gang location and every cubic inch counts.
Better elsewhere: finished-drywall retrofits, where a screw-in old-work box does the same job without nails.
4. 4″ Square Steel Electrical Box Kit, Two 20A Tamper-Resistant Duplex Outlets
Everything for four grounded plugs in one bag, including the receptacles themselves.
A different animal from the bare boxes above — this is a complete surface kit. The box is drawn steel, meaning the body is formed from a single piece of metal with no welded seams to split when conduit gets torqued down. Interior capacity is 21 cubic inches at a 1-1/2 inch depth, and there is a raised ground provision with the screw already in place for a clean bonding path. In the bag you get the 4×4 steel box, a raised 2-gang duplex receptacle cover, two tamper-resistant receptacles (shutters that keep small objects out of the slots), and the copper grounding screw and wire. Nothing else to buy for the four outlets.
Sixteen knockouts are stamped into the shell — ten at 1/2 inch and six at 3/4 inch, arranged as eight and four on the sides plus two of each on the bottom. Whatever direction the conduit arrives from, there is an opening waiting, and the unused ones stay closed. The receptacles are commercial grade: full saddle yoke, self-grounding, impact-resistant face, rated 125V 2-pole 3-wire at 20 amps. That is the rating you want when a shop vac, a compressor, and a space heater are all sharing the same box. Because the box is metal and surface mounted, it holds grounding continuity and physical protection that a plastic box in the same exposed spot cannot.
Completeness is the thing that gets praised most here — owners mention that everything needed for a four-outlet box is genuinely in the package, and it lands cheaper than assembling the same parts at the home improvement store. Two caveats stand out. Value is contested: some find it a strong buy, others a little costly for a single box. And fit has its quirks — the outlets sit deep in the box, which can crowd the wiring, so wire carefully and confirm your devices seat the way you want before you button it up. An occasional unit arrives feeling tight rather than roomy. Owners wiring it into a garage bench or a rack setup treat that as a routing task, not a dealbreaker.
Why It Wins In A Shop
- Complete kit — box, cover, two 20-amp tamper-resistant duplex receptacles, and grounding hardware
- Sixteen knockouts in 1/2-inch and 3/4-inch sizes for flexible conduit routing
- Drawn steel, single-piece body with a raised ground provision and screw pre-installed
- Self-grounding, impact-resistant 125V 2-pole 3-wire receptacles rated at 20 amps
The Fair Warnings
- Deep outlet mounting can crowd the wiring, so dress the cables before you close it up
- Value is a split verdict — some buyers think it is priced a bit high for one box
- Exposed-surface design only; nothing here is meant to be buried in drywall
Reach for this if: you want four grounded outlets on a garage or basement wall and would rather not assemble the kit yourself.
Look elsewhere if: the box is going inside a finished wall — this one is built to sit out in the open.
5. 2-1/8 Inch Deep Four Gang Multi Device Switch Box-1 per case
A compact steel box for four light switches in one tidy row on a shop wall.
Four separate switches for four separate lighting rows is exactly the job this one is cut out for, and buyers who have done that job call it perfect for the purpose. The body is alloy steel with a glossy finish, screw-in mounted, and 2-1/8 inches deep — shallow enough to stay out of the way in a wall you are not trying to rebuild. The manufacturer is Garvin, model MGSB-4. It arrives one per case, so plan your count before you order.
Where the plastic boxes above are light and quick, this one is the metal option: a steel switch bank feels rigid in a way that matters when four rockers are getting pushed every day. Owners mounting it in a steel-built garage needed separate switches for separate rows of lighting, and reported it went in easily and fit the opening as expected. It has shown up on workshop walls for four-switch banks too, and it is one of those parts that simply is not stocked at the local hardware store — availability is a real buying reason, not a marketing one. It is described as compact in style, so the shallow profile keeps the wall face neat.
Price is the recurring complaint: it is not a cheap box, and a buyer or two calls it a little expensive for what it is. That is the honest trade — you are paying for a specific size and a steel shell that big-box aisles often do not carry. For a garage or workshop lighting bank, that trade makes sense. If a plastic box of the same shape is on the shelf and fits, it will save you the premium.
Where it shines: steel rigidity and a compact 2-1/8-inch depth for a four-switch bank that will be used hard and often.
What to accept: it is priced like a specialty part — because in a lot of places, that is what it is.
Pick this when: you want a rigid steel box for four switches and your local aisles simply do not stock it.
Second-guess it if: the width or depth you need matches a cheaper plastic box that is already on the shelf.
6. Arlington TVB613-1 Recessed TV Outlet Box with Paintable Trim Plate, White, 4-Gang
A box that sits behind the drywall so a wall-mounted TV can hang flat and clean.
The reason this exists is simple: a standard box leaves the plug sticking out into the room, and that is exactly what stops a TV or a console from sitting flush. The 26.2-cubic-inch interior is recessed so plugs tuck into the wall cavity rather than past it. A textured, paintable trim plate covers the rough edges of the drywall cut and can be matched to the wall color or sprayed to disappear entirely. Positioning tabs are set for 1/2 inch wall thickness so the box lands accurately on the stud, and it can go horizontal or vertical depending on how you want the devices to face. It is UL and CSA listed with a grounding lug.
Inside, the layout splits high-voltage from low-voltage so audio, HDMI, and network cable have their own path and a divider keeps the two legally separated. Fits between 16-inch on-center studs without drama, and the oversized trim ring means an overcut hole is not a disaster. Strong plastic, open mounting points for the low-voltage runs, and a two-gang power side for outlets are the details that make it work. A wireless hub can sit concealed in the cavity, and there is room for cable TV power supplies and similar bricks that would otherwise hang in view. It comes in white with black also available in this family.
Installation is what comes up most in the feedback — a solo install after cutting the hole and snaking the wiring, and the result is clean and tidy. The plastic can be brittle under impatience: a screw attachment point cracking during a rushed fit is the failure to avoid, so set the screws gently and let the trim hide the cut rather than cover for a sloppy one. It is also a recessed new-work design, so it wants an open wall or a careful retrofit cut, not a swapped-in old-work wing.
The reason it earns its place: the recessed 26.2-cubic-inch cavity keeps plugs inside the wall so the TV and console can sit flush against the drywall.
Handle with patience: the plastic screw points do not tolerate a rushed install, so snug rather than crank them down.
Best fit: a wall-mounted TV or entertainment center build where hidden cable and flush mounting are the whole point.
Not for: a plain four-outlet wall where no TV or low-voltage cabling is involved — the recessed depth would be wasted.
7. Arlington Industries DVFR4W-1 Recessed Electrical Outlet Mounting Box with Paintable Wall Plate, 4-Gang, White
The recessed box you can drop into a finished wall for outlets and low-voltage together.
Where the TVB613-1 is built for a new-wall TV install, this one is aimed at existing homes and new construction alike — it is the retrofit version of the same idea. The box is recessed so plugs do not extend past the wall, which lets furniture and media consoles sit closer to the surface. It handles both low voltage (audio, HDMI) and high voltage (regular electricity) in the same four-gang housing, and a divider separates them. Inside the kit are the box itself, four old-work wings, a textured paintable trim ring with white screws, and a high/low-voltage divider. It is screw-in mounted, and the trim is paintable to match the wall.
For anyone running a TV wall in a house that is already finished, this is often the answer. Four-gang capacity covers four low-voltage jacks, or a mix of outlets and brush plates for HDMI, coax, and Cat 6. The old-work wings clamp against the back of the drywall, and it works in awkward surfaces like plaster over brick. The large openings on the top and bottom are a deliberate design choice — they make feeding wire through the box far less of a chore than threading a closed shell. A three-box installation behind a TV and two cabinet stacks is the kind of job this was built for, and the result is a clean face rather than a tangle of cords.
The one limitation is interior room. It works well but can run short for a lot of cable connections, and one owner had to trim the back with a multi-tool to feed the cables through — an extreme fix, but a sign of the space limit. The interior is deeper than strictly necessary for some wiring, which eats into the room conductors need. And installation is described as tedious but effective: it will take patience and a steady hand, especially in a hard wall. Treat it as a cable-management box first and a plain outlet box second, and the trade feels fair.
Where It Delivers
- Recessed four-gang housing that fits four low-voltage jacks or a mix of outlets and brush plates
- Divider keeps low-voltage and high-voltage wiring legally separated
- Old-work wings clamp into a finished wall, and it works in plaster over brick
- Large top and bottom openings make wire feeding convenient; trim is textured and paintable
What To Plan Around
- Interior room can run short when you are landing a lot of cable connections
- Installation is tedious but effective, so budget the patience for a hard wall
- The cavity is deeper than every wiring job requires, which narrows conductor space
Made for: existing-wall TV and media builds where outlets and HDMI need to share one recessed four-gang box.
Think twice if: you only need four plain outlets with no low-voltage runs — the divider and recessed depth would be extra moving parts.
Understanding the Specs
Cubic-inch capacity
Capacity is the interior volume of the box, measured in cubic inches, and it is the number that decides how comfortably four devices and their wiring fit. A four-gang location often carries a feed-through circuit as well, and that extra cable eats into the same space. More capacity means easier folding, less strain on terminals, and a shorter fight when you push the devices home. The boxes here range from 21 cubic inches in a shallow exposed steel box up to 71 cubic inches in a deep old-work retrofit box — check the count before you commit, especially if you are pulling more than one circuit through.
New-work vs old-work mounting
Mounting type decides whether the box is even usable on your wall. New-work boxes have captive or fixed nails on the side and get driven into a stud before drywall goes up — fast, cheap, and only available while the wall is open. Old-work boxes use wings or tabs that clamp against the back of finished drywall, so they work in a room that is already painted and furnished. Recessed boxes in this group follow the same logic: one recessed model is aimed at new walls, and another is set up for existing homes. Pick the wrong type and no amount of capacity will save the install.

Final Thoughts: The Verdict
For most jobs, the best 4 outlet box is the 4-Gang PVC New Work Switch/Outlet Wall Electrical Box, because it nails to a stud in seconds, carries ETL certification and a 2-hour fire-resistance rating, and comes three to a pack so an entire rough-in is covered in one order. If your wall is already finished and you need the most interior room to fold wire, the Carlon B468R gives you 71 cubic inches and screw-in wings — just snug the tabs rather than torque them. For a garage that needs four outlets and a shop-grade enclosure, the 4″ Square Steel kit has everything in the bag, and the Arlington TVB613-1 is the one to reach for when the goal is a flush, cord-free TV wall. And if a heavy four-gang location needs every conductor to fit, the ETL-listed 4-Gang PVC New Work box is the one that holds up to 30 14-gauge wires.
