"The affordable Silver Spring Plastic Multi-Height Threshold Ramp is an easy way to increase accessibility without straining your budget. Designed to ship compactly, it’s easy to assemble on arrival and provides everything you need to safely roll a wheelchair or drive a mobility scooter into or out of your home, patio or other hard-to-reach location. The Plastic Multi-Height Threshold Ramp is manufactured to be as lightweight as possible, weighing only 4 lbs., without compromising on strength. The lattice/honeycomb construction provides over 800 lbs. of support, easily accommodating full-size mobility scooters. The interlocking design allows you to set the height at 1"", 2"" or 3"" depending on the rise. Designed primarily for outdoor or garage use, each ramp piece has underside channels so that cables or wires can pass through without hinderance, and the open top allows precipitation to fall through without accumulating on the ramp surface. Adhesive tape strips are included to secure the ramp in place, and each ramp comes with pre-drilled holes for optional permanent installation (hardware not included)."
