Goyappin Ladder Jacks for Scaffolding Platform 2 Pack,Heavy Duty Steel Jack Scaffold Bracket,Two-Rung Short Body Extension Ladder Jack for Roofing Painting Jobsite 20 inch Platform Withstand 350 LBS

Why I Picked These

I needed to repaint the fascia on a two-story gable and wanted a stable, mid-span work platform without dragging a full scaffold to the site. The Goyappin ladder jacks promised a 20-inch plank platform and a respectable 350 lb rating. I put them through a mix of painting and light roofing tasks over a week—mostly on fiberglass and heavy-duty aluminum extension ladders—and came away impressed by their build, with a few caveats around adjustability and documentation.

Build Quality and Design

The Goyappin ladder jacks are welded steel with a bright orange finish that’s easy to spot in a crowded truck bed. The welds on my pair were clean and consistent with no visible porosity, and the parts lined up true, which matters when you’re depending on the bracket to bite into a ladder rung securely. The steel is substantial enough that nothing feels springy underfoot. That rigidity pays dividends when you’re standing mid-plank: less bounce, more confidence.

These are short-body, two-rung style jacks. They clip onto two ladder rungs and offer an adjustable bracket that supports a plank. The geometry is well thought out: the hooks engage positively, the support angle stays square as you load it, and there’s enough adjustability to fine-tune plank pitch to match your ladder angle. They’re designed around a 20-inch platform, which is a generous width for comfort and tool space. If your go-to planks are narrower, you may want to add cleats to keep them centered and locked.

The 350 lb rating covers user plus tools plus the plank. On my heaviest setup—me at around 200 lbs with a loaded pouch, caulk, and a coil of hose—I never saw any sign of flexing from the jacks. The limiting factors were the ladders themselves and the substrate under the feet, not the brackets.

Setup and Installation

Out of the box, I didn’t find any instructions, and that could frustrate a first-time user. The assembly is straightforward enough if you’ve installed ladder jacks before: attach the support arms to the body, install the adjustment hardware, and make sure the locking nuts are seated so nothing backs off with vibration. A pair of wrenches is all you need. Still, a one-page diagram would save guessing which fasteners go where.

Mounting to the ladders was quick. Clip onto two solid rungs at equal heights on both ladders, set the bracket angle to level the plank, and snug everything down. The design allows easy micro-adjustments to square things up once the plank is in place. With practice, I was setting a platform in under 10 minutes by myself. If you’re new to ladder jacks, budget extra time for careful alignment the first go.

A note on planks: these jacks are happiest with a 20-inch aluminum stage. Wood walkboards will work if they’re rated appropriately, but the fit won’t feel as “locked in” as an aluminum stage with proper end hooks. Whatever you use, confirm the plank’s rating and secure it against shifting.

On-the-Job Performance

Once set, the platform felt steady and confidence-inspiring. I used the setup to scrape, prime, and paint fascia and to replace a couple of starter shingles along a lower roof edge. Walking the plank was predictable, with no “trampoline” bounce. Lateral stability is mainly a function of your ladders and how well you’ve stabilized the feet; the jacks transmit load cleanly without introducing extra wobble.

Getting materials and tools up wasn’t a chore. The 20-inch width gives you breathing room for a tray, quart can, and a few hand tools without crowding your footing. For heavier or bulkier materials, I still prefer to hoist with a rope so I’m not climbing with full hands, but that’s standard best practice.

Noise and vibration were minimal. I didn’t have any loosening hardware after several moves, but I checked the nuts every time I relocated the setup. The finish handled a week of scuffs with only light cosmetic scratching at the corners and contact points—a good sign for corrosion resistance, though I’ll keep an eye on the weld toes after a season of use.

Height and Adjustability Limits

The short-body design is both a strength and a limitation. It keeps the jacks lighter and more compact, and it’s ideal for low-to-mid elevations: siding repairs, window trim, fascia and soffit work, and low roof edges. But you won’t get the same vertical reach or platform height flexibility you’d see from long-body jacks. The fixed spacing of ladder rungs further constrains where your plank can land.

If your work frequently sits above mid-second-story windows, or you need to span significant elevation differences between the two ladder locations, you’ll want either a long-body jack system or a different access method (pump jacks or modular scaffold). For the 10–18 foot working range, these are right in their element.

Compatibility and Best Pairings

I ran these on Type IA fiberglass and a heavy-duty aluminum extension ladder. They seated cleanly on both. The sweet spot is a stiff ladder—fiberglass or robust aluminum—rated to match or exceed the load you plan to put on the platform. Lightweight ladders can telegraph a bit of wobble under full load, which isn’t the jack’s fault but affects the feel. Make sure both ladders are the same model or at least have similar rung profiles so the jacks sit symmetrically.

As for surfaces, they were fine against wood and aluminum rails with no marring beyond normal rub marks. If you’re concerned about paint scuffing, a strip of tape on the ladder rails at the hook points isn’t a bad idea.

Safety Notes That Actually Help

A few habits made a noticeable difference in stability and comfort:

• Set ladder angle to roughly 75 degrees (4:1 rule) and test by standing on the first rung—your arms should just reach the rails.
• Use ladder levelers or pads to get both ladders truly plumb and on firm footing; shim soil if needed.
• Tie off both ladders at the top if you can, and stake or weight the feet. A couple of straps go a long way toward a solid feel.
• Use a plank rated for the load, ideally a 20-inch aluminum stage. Cleat or secure it so it can’t creep.
• Don’t exceed the 350 lb combined rating once you add the plank’s weight, your weight, tools, and materials.
• Keep the platform free of debris and liquids. A clean, dry stage is safer and less stressful to work from.

These aren’t unique to this product, but the jacks reward good setup with a notably sturdy platform.

Portability and Storage

One of the appeals here is how easy these are to live with. The short-body format packs small; I stored them flat in a side bin without hogging space. Carrying them up a driveway with ladders on a dolly was no strain. Hardware stayed put between moves, but I still toss the extra bits in a pouch so nothing goes missing on site.

Where They Fall Short

Two things could be better:

• Documentation: Mine came without instructions. It’s not rocket science, but a basic diagram and parts list would cut setup time and ensure folks torque hardware correctly.
• Reach: The short-body architecture limits how high and how fine-tuned you can set the platform. That’s inherent to the design, not a flaw in execution, but it’s worth calling out if you often work at taller elevations.

A minor nit: the finish will pick up scuffs quickly in real use. Not a functional issue, but you’ll want to knock off nicks before storage if you’re meticulous about rust prevention.

Value

If you already own two stout extension ladders and a rated plank, this setup pays for itself quickly compared to renting scaffold for scattered small jobs. It’s not a substitute for a full staging system on extensive exterior projects, but for targeted tasks across a facade, it’s an efficient middle ground.

Recommendation

I recommend the Goyappin ladder jacks for painters, roofers, and serious DIYers who need a compact, sturdy platform for low-to-mid height work. They’re solidly built, easy to deploy once you’ve sorted the initial assembly, and confidence-inspiring underfoot. Just be mindful of the short-body limitations and pair them with heavy-duty ladders and a proper 20-inch plank. If your work regularly demands more vertical adjustability or guardrails, look to long-body jacks or a pump-jack/scaffold system. For everything else in that 10–18 foot working range, these are a reliable, portable solution.
