Finding a stable platform to mount a tall horse, access an RV, or reach a high truck bed shouldn’t require balancing on a wobbly bucket or a flimsy plastic crate. A solid, correctly sized 3 step mounting block gives you the secure footing and extra height needed to swing into the saddle or step into your camper without straining your joints or risking a fall.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent hundreds of hours analyzing the structural integrity, weight capacities, material densities, and real-world stability of mounting blocks to ensure this guide covers only the most reliable options.
Whether you are an equestrian rider or an RV owner, the right platform makes a significant difference. This guide breaks down every crucial detail to help you confidently select the best 3 step mounting block for your specific needs.
How To Choose The Best 3 Step Mounting Block
Not all mounting blocks are built the same, and choosing the wrong one can lead to instability or a short lifespan. Focus on three core aspects to ensure your block provides safe, reliable service for years.
Weight Capacity and Step Height
Always check the maximum weight limit, as this directly determines the block’s structural integrity. A 300-pound capacity is a standard baseline for most adults, but some premium units can hold significantly more. Step height is equally critical — the total height of the block, usually between 15 and 25 inches, must be tall enough to make mounting comfortable without leaving you straining.
Material and Durability
Polyethylene (PE) is the most common material for equestrian blocks because it is UV-resistant and durable, but it can be heavy. Aluminum offers extreme portability and rust resistance, making it ideal for RV use. Steel, often found on RV-specific steps, provides maximum stability but at a higher weight. Your choice should match the environment — a barn block needs different properties than a dock step exposed to saltwater.
Base Stability and Surface Grip
A wide, non-tipping base is non-negotiable for safety, especially on grass or uneven ground. Look for blocks with a broad footprint or built-in pedestal design. The tread surface must have aggressive anti-slip properties — either molded-in texture, rubberized pads, or applied anti-skid tape. This prevents your foot from sliding, particularly in wet or muddy conditions.

In‑Depth Reviews
1. Horsemen’s Pride 3 Step Mounting Block 0093
The Horsemen’s Pride 3 Step Mounting Block earns the top spot because it delivers the ideal combination of height, stability, and durability that serious equestrian riders need. Standing at a full 21 inches with three wide steps, it provides enough elevation to comfortably mount the tallest horses without requiring a running start or straining your lower back. The high-density polyethylene construction is incredibly tough — several owners report using these blocks daily for years without any cracking or warping, and the black color resists fading even after prolonged sun exposure.
This block features a built-in handhold on the front for easy carrying, though at around 13 pounds it is not the lightest option available. Some users noted that the steps can collect rainwater if left outdoors, requiring small drainage holes to be drilled in the bottom corners. The wide 18.75-inch square base offers excellent stability on packed ground, and the 300-pound weight capacity comfortably accommodates most riders and gear.
Customers consistently praise its solid feel and the confidence it gives both novice riders and aging equestrians. Many riders specifically mention that the 21-inch height is the perfect sweet spot — taller than standard 2-step blocks but not so tall that it feels unsafe or tipsy. For daily barn use where reliability and height matter most, this block is the clear choice.
Why it’s great
- 21-inch height provides the best mounting elevation for tall horses
- Extremely durable high-density polyethylene with UV resistance
- Wide, stable base reduces tipping risk on uneven ground
Good to know
- Steps can collect water if left in rain without drilled drainage
- Heavier than aluminum alternatives at roughly 13 pounds
2. Taylor Made Products StepSafe Dock Steps
The Taylor Made StepSafe Dock Steps are engineered specifically for marine environments, making them the ultimate choice for boat docks, pools, and other wet areas. This triple-tread version stands 25.5 inches tall with a massive 35-inch by 25-inch footprint, providing an exceptionally stable and spacious platform. The UV-resistant polyethylene construction is formulated to withstand constant sun exposure and saltwater corrosion without degrading or becoming brittle, a common failure point for lesser blocks.
Each step features molded-in non-slip pads for maximum safety, though some owners have reported minor quality control issues with the strips being misaligned upon arrival — this is typically an easy fix by repositioning them. The steps come pre-drilled with hardware included for permanent bolting to a dock, which is highly recommended as the light weight can allow the step to shift if not secured. Weighing in at 22 pounds, it is not designed for frequent relocation, but it is still portable enough to move between the dock and pool seasonally.
Owners who have bolted these steps down report they remain solid through harsh winters and hurricane-force weather without flexing or cracking. The non-slip surface provides reliable grip even when wet, and the generous tread depth accommodates larger feet comfortably. For anyone needing a permanent, weather-proof mounting solution near water, this is the safest and most durable pick.
Why it’s great
- Marine-grade UV and saltwater resistant construction
- Tall 25.5-inch height with an extra-wide, stable base
- Non-slip molded pads on every step for wet-condition safety
Good to know
- Best performance requires bolting to a dock for stability
- Heavier unit at 22 pounds, not for frequent carrying
3. High Country 2-Step Mounting Block
The High Country 2-Step Mounting Block fills a specific niche for riders who find standard 2-step blocks too short but do not need a full 3-step unit. At 19 inches tall, it sits between typical 15-inch and 21-inch blocks, providing that extra lift for mounting taller horses while remaining lower to the ground for stability. The forest green color blends well into pasture settings, and the polyethylene material is built to last with a lifetime warranty from the manufacturer, a strong vote of confidence in its durability.
Weighing just 13 pounds, this block is light enough to carry from barn to pasture without strain, yet its wide pedestal base offers surprising stability on uneven ground. The steps are wide and deep, providing plenty of room for secure footing, though some users wish the top step had a slightly wider platform for more comfortable standing.
The lifetime warranty and proven longevity make this a smart investment for riders who want a block that will outlast their equestrian career. While it is only a 2-step design, the taller step height effectively gives you the mounting advantage of many 3-step blocks without the added weight. For riders on a premium budget who prioritize long-term value and moderate height, this is an excellent choice.
Why it’s great
- Taller 19-inch step height bridges the gap between 2-step and 3-step blocks
- Lifetime warranty through High Country Plastics
- Lightweight at 13 pounds with a wide, stable base
Good to know
- Only 2 steps, not a traditional 3-step configuration
- Limited color options available
4. Kinchoix 3 Step RV Stairs with Handrail
The Kinchoix 3 Step RV Stairs are purpose-built for stationary camper and trailer use, offering a level of safety and convenience that factory pull-out steps simply cannot match. A standout feature is the included handrail, which reaches 34 inches from the top platform and provides essential support for anyone needing extra stability when entering or exiting. The carbon steel construction with 2mm thick step panels and triangular stabilizing bars gives this unit an exceptionally rigid feel, handling up to 300 pounds without any wobble.
Assembly takes around 20 minutes with the included Allen wrench, and the handrail can be mounted on either the left or right side for flexibility. The stair rise increments are 7 inches each, totaling a 20-inch overall height that aligns perfectly with standard 28-foot camper door sills. Non-skid tape is included and can be cut to size, providing reliable traction even in muddy campsite conditions. Some customers noted occasional shipping damage to the tubular components, but the protective packaging is generally effective.
Owners who have installed these steps report they feel significantly sturdier than factory options, with no dangerous flexing or bouncing during use. The ability to separate the handrail into three threaded sections makes storage manageable when traveling. For RV owners who set up camp for extended periods and want a solid, stair-like entry solution, this is the top mid-range option.
Why it’s great
- Includes a 34-inch handrail for added safety and support
- Thick 2mm carbon steel with triangular braces for maximum stability
- Non-skid tape included to improve wet-surface traction
Good to know
- Requires assembly of about 20 minutes
- Not designed for frequent folding or mobile use
5. Horsemen’s Pride 2-Step Mounting Step
The Horsemen’s Pride 2-Step Mounting Step has been a staple in the equestrian community for over two decades, and for good reason — it offers a rugged, no-nonsense design that stands up to daily abuse in barns and riding rings. At 15 inches tall with 18.75-inch long steps, it is shorter than most 3-step blocks, making it ideal for mounting average-sized horses or for use by younger riders. The red polyethylene construction is fade-resistant and holds up well in all weather conditions, and the built-in handle makes lifting and moving it effortless despite its 11.5-pound weight.
Some owners have noted the steps are not as wide as anticipated, and the slightly recessed surface of each tread can collect water and attract insects if left outdoors. However, the wide 20-inch base provides solid stability on most surfaces, and the 300-pound capacity covers the vast majority of riders. The step has a slight bow under heavy load but remains structurally sound — a testament to the forgiveness of polyethylene as a material.
Business owners running riding schools particularly appreciate this model for its durability and ease of cleaning with a hose. The red color makes it highly visible and easy to spot even in a busy barn aisle. While it is only a 2-step, its proven track record and reliable performance make it a worthy mid-range contender for riders who do not need extreme height.
Why it’s great
- Proven track record with decades of positive equestrian use
- Lightweight at 11.5 pounds with a convenient carry handle
- Fade-resistant red polyethylene is easy to clean
Good to know
- 15-inch step height may be too short for tall horses
- Recessed step surfaces can collect water and debris
6. DEPSUNNY Adjustable RV Step Stool
The DEPSUNNY Adjustable RV Step Stool is a cleverly designed solution for RV owners and campers who need an ultra-portable mounting aid without sacrificing adjustability. Constructed from premium aluminum, this step stool weighs just 4.2 pounds and folds flat for storage, making it one of the most travel-friendly options on this list. The adjustable height feature offers three settings — 8, 9, and 10 inches — allowing you to fine-tune the step height to match different vehicle sills or ground conditions.
The wide anti-slip surface pattern provides good traction, and the reduced gap design between the support panels makes it more comfortable for pets who might also use the step. The aluminum frame is rated to support up to 1,000 pounds, a remarkably high capacity that speaks to the welding quality and material strength. The foldable legs allow it to slip behind a seat or into a storage compartment with ease. One note: the step is narrow relative to larger mounting blocks, and the adjustable locking mechanism requires a firm push to engage correctly each time.
Owners recovering from surgery or with limited mobility have found this stool indispensable for getting into lifted Jeeps and trucks. The powder-coated black finish resists scratches and corrosion reasonably well, though it can show wear over time with heavy use. For budget-conscious RVers and campers who prioritize weight and packability above all else, this is the perfect entry-level companion.
Why it’s great
- Ultra-lightweight 4.2 lb aluminum construction folds flat
- Three adjustable height settings for versatile use
- Impressive 1,000 lb weight capacity in a small package
Good to know
- Narrower step platform may feel less stable than wider blocks
- Adjustment mechanism requires deliberate action to lock
7. Horsemen’s Pride Jump Block (Pair)
The Horsemen’s Pride Jump Block is a specialized product for equestrian training rather than direct mounting, but it earns its place on this list as a versatile, stackable platform that can be repurposed for mounting in a pinch. Sold as a pair, each block measures 20.25 inches long by 15.25 inches wide by 9 inches high, and they can be stacked to create a 2-step or 3-step configuration, though stability when stacked should be carefully assessed. The thick-walled high-density plastic is incredibly strong for its weight — each block weighs only 16 ounces — making them easy to rearrange during training sessions.
These blocks are primarily designed for setting up jumping grids and cavaletti work, allowing trainers to quickly change fence heights without any tools. The smooth, rounded edges are safe for horses and riders, and the blocks have enough durability to withstand being knocked over repeatedly. As a mounting block, the 9-inch single height is generally too low for most riders, but stacking two blocks provides a usable 18-inch step that can serve in a pinch for smaller horses or ponies.
Trainers and lesson barn operators love the versatility these blocks offer for pattern work and progressive jump training. An 8-year-old student can easily carry and position them, promoting independence in learning. For riders who need a lightweight, multi-use training tool that occasionally doubles as a low mounting step, this pair is an excellent budget-friendly addition to the tack room.
Why it’s great
- Extremely lightweight at 16 oz each, easy for any age to move
- Stackable design enables multiple height configurations
- Versatile for both jumping training and light mounting use
Good to know
- Single 9-inch height is too low for most direct mounting needs
- Stacked stability requires careful placement to avoid tipping
