This rollup ramp (3' long by 2' 6" wide) rolls into a cylinder when not in use, making it easy to transport. When rolled up it has a diameter of 6". It is made of aluminum, weighs only 16 pounds, yet can support loads of up to 600 pounds. Rollup ramps are designed to bridge the gap over steps, curbs, and raised landings and they can be used with scooters and wheelchairs of all types. To use a rollup ramp, simply unroll the non-skid track and attach the sides rails for rigidity.
