ABSTRACT:
A low pitched, wedge-shaped ramp has flanges on two sides and to provide easy access for a wheeled device such as a wheelchair, the ramp has a flattened frontal edge. An upwardly angled top surface has indented tread squares across a major portion for wheel position frictional maintenance. The ramp is manufactured of recycled rubber for strength and light weight and can be moved easily from place to place. Designed for door threshold use, the underside of the ramp has a framed indentation for restricting ramp slippage.
