As their name implies, these are made for a very short rise, which would typically occur at a door opening. Some of these areas may not look like much, but a rise of 1½" might as well be a brick wall when you hit it with the tiny front wheels of a wheelchair. These are typically made from either aluminum with a non-skid surface or solid rubber.
Aluminum threshold ramps are made from a non-slip, non-rusting, all aluminum construction that is OSHA approved.
Made of 100% recycled tires, the rubber threshold ramp is inexpensive, durable, easy to install and designed for continued use without any wear and tear. Rubber threshold ramps will not rust or corrode and they can be installed or removed in minutes.
