Hanging accordion doors comes down to a level top track, secure hardware, and a final fold test — most DIYers finish in under two hours.
Few things date a closet faster than a sagging, sticking accordion door. The good news? Installing a new one is a genuinely achievable weekend project — provided you respect the sequence. The track must go up level and centered first, then the panels hang from it, and only then does the latch hardware go on. Jump ahead and you’ll fight binding folds and misaligned magnets for years.
This guide walks through the core steps that appear in manufacturer instructions across brands, plus the mistakes that send DIYers back to the hardware store.
What You’ll Need Before Starting
Gather these before you touch a screwdriver. Most accordion door kits include the track, panels, and hardware, but you’ll likely supply the tools.
- Tape measure — for the opening width and height, checked at least twice.
- Level — a 2-foot or longer level keeps the track true.
- Hacksaw — for trimming the track when the kit runs wide (more on that below).
- Cordless drill with screwdriver bits — plus a 3/8″ drill bit if you need to drill a strike hole.
- Step ladder and, ideally, a helper for the hanging step.
One thing to check before buying: some systems require a minimum wall height. At least one manufacturer’s guide specifies walls at least 7 feet tall for their door to install correctly, so confirm your opening qualifies before you commit to a particular kit.
The Step Order That Works
Every brand sequences things slightly differently, but the logic is consistent: prepare the opening, mount the track, hang the panels, then finish the latch. Here’s the order that shows up again and again in documented instructions.
1. Measure and Trim the Track
Measure the opening width and height before anything else. Compare those numbers to the door kit’s specifications. If the track is wider than the opening, you can shorten it with a hacksaw — one manufacturer guide says to dry-fit the track first, cut it to length, and clean out all metal shavings before assembly. Skipping that cleanup lets debris jam the glides later.
2. Mount the Top Track Level and Centered
Position the track at the top of the opening, centered and straight, and fasten it with screws. A level is non-negotiable here — an out-of-level track causes binding, poor folding, and latch misalignment that you’ll chase forever. One guide describes starting with a ¾” track screw through the mounting hole nearest the center, then rotating the track into position before fully securing the rest.
Fasten into solid structure, not just drywall. Screws need to bite into the header, jamb, joist, or beam behind the wall surface, or the track will pull loose under the door’s weight.
3. Hang the Panels
This is the step where manufacturer instructions diverge most. Some kits use wheels that ride in the track; others use glide rings and top glides, or pivots. Follow the hardware style your kit shipped with — these aren’t interchangeable.
One documented approach: install glide rings and top glides on the panels first, then feed the track onto the wheels. Another guide warns explicitly: “Main carton must not be removed until door is suspended in track.” The door stays protected in its packaging until it’s actually hanging, then you slide it along the track to the secured portion before removing the carton.
A helper makes this step dramatically easier. You’re holding a door panel overhead while aligning track screws — that’s a two-person job done safely.
4. Secure the Fixed Side and Latch
Once the door hangs freely, install the fixed anchor panel on the non-opening side and screw it to the jamb or wall. One manufacturer guide specifies No. 6 x 1½” flat head screws for the jamb panel, and says to fasten it in at least three places — low, middle, and high — to keep it from bowing.
Then mark where the door’s latch contacts the jamb and install the magnetic striker plate at that spot. Some systems require drilling a strike hole first — one guide calls for a 3/8″ drill bit at 1/2″ depth — while others use surface-mount plates.
Hand-tighten screws during this phase. One manufacturer explicitly warns against over-tightening, which strips the screw holes and weakens the whole assembly.
5. Test the Fold and Adjust
Open and close the door several times. The panels should fold freely with no binding, and the latch should catch cleanly without forcing. If the door sticks or leaves gaps, loosen the track screws slightly, nudge the track, and retighten. Small adjustments here fix most alignment problems.
| Step | Key Detail | Common Mistake |
|---|---|---|
| Measure opening | Width and height, twice | Skipping the tape measure and buying the wrong kit size |
| Trim track | Hacksaw, then clean shavings | Leaving debris that jams the glides |
| Mount track | Level and centered, into solid structure | Screwing into drywall alone; out-of-level track |
| Hang panels | Feed track onto wheels; keep carton on until suspended | Removing packing too early; working without a helper |
| Secure jamb panel | Fasten low, middle, high | Under-fastening causes bowing |
| Install latch | Mark contact point, mount striker plate | Misaligned magnet from an unlevel track |
| Test fold | Full open/close cycle, check latch | Over-tightening screws and stripping holes |
Compatibility Caveats Worth Knowing
Accordion door kits are model-specific in ways that matter. Some use wheels, some glide rings, some require magnetic latch plates, and some need support clips. Installation steps are not interchangeable across brands — always read the instructions that ship with your specific kit before you start. The general sequence here holds for most systems, but the hardware details will differ.

FAQs
Can one person install an accordion door?
Technically yes, but it’s not pleasant. The hardest moment is feeding the track onto the wheels while holding the door panel overhead — a helper makes that step safe and far less frustrating. If you must work alone, use a step ladder and rest the door’s weight on a box or sawhorse while you secure the first few track screws.
Do accordion doors need a floor track?
Most residential accordion doors hang from a top track only, with the bottom panels guided by a floor or threshold guide. That bottom guide keeps the door from swinging and helps it track straight. Some kits omit it for carpeted openings, but the door will drift without one on hard floors.
What do I do if the door sticks when folding?
Start by checking the top track with a level — an unlevel track is the most common cause of binding. Loosen the track screws, shim or nudge the track level, and retighten. Then check that the panels hang plumb and that no debris is caught in the glides. The latch misalignment usually resolves itself once the track is true.
