Bariatric Threshold Ramps are designed for doorways and made of lightweight durable aluminum. Gaining access into and out of your home is simple. The bariatric threshold ramp features the highest weight capacity for any threshold ramp and includes an anti-slip, high traction sandpaper surface, making it safer and easier to use the ramp while in a wheelchair or scooter. The ramps are constructed of aluminum, making them lightweight, easy to handle, and rust proof for worry-free use outdoors.
