"The deluxe power scooter hitch-mounted carrier rack is a quick, simple, safe, and affordable means for transporting scooters or wheelchairs. The surface is 46.5"" long x 28"" wide, providing enough space for most of today's mobility devices; 4.25"" high side rails feature 10 different tie down points for securing the power wheelchair or scooter to the rack. Folds up when not in use, and with a 500 lb. capacity, the mobility carrier quickly attaches to most 2"" Class III or IV hitch receivers."
