A doorway threshold that’s just one inch high doesn’t seem like a big deal—until you’re trying to roll a wheelchair, walker, or even a heavy dolly over it. The Ruedamann 1-Inch Threshold Ramp solves that specific problem with a wide, low-profile rubber wedge. It spans 35.4 inches across and extends 5.9 inches out from the step, giving you enough room for a smooth transition without creating a tripping hazard.

The rubber construction is dense and heavy, rated to hold 1,500 pounds. That means it won’t shift under a power chair or a loaded hand truck. The surface is covered in a crosshatch groove pattern that provides real traction, even when wet. We tested it after a rainstorm, and the grip stayed reliable for both wheels and feet. It’s also non-slip on the bottom, so it stays put on tile, concrete, or wood floors without adhesive.

One thing to note: this ramp is not adjustable or foldable. You get a fixed 1-inch rise, so measure your threshold height carefully before buying. It works best for standard doorways, shower entries, or garage lips where the height is consistent. The rubber is tough and weather-resistant, but it will collect dirt in the grooves over time—a quick rinse handles that. For a straightforward, heavy-duty solution to a common accessibility headache, this ramp delivers exactly what it promises.
