"The Titan Ramps 6' x 48"" Aluminum Wheelchair Entry Ramp is the perfect solution for a semi-permanent access ramp to your home or commercial business. These ramps are carefully designed using corrosion-resistant aluminum for years of maintenance free use, making these entry ramps an excellent investment. The 48"" W design complies with the Massachusetts and California Building Code. The ramps feature a slip resistant surface which is ideal for wheelchairs, scooters, walkers, canes, and crutches. These solid ramps also have a top lip transition plate, allowing the transfer from the ramp to the raised surface effortless. The 6’ ramp should be used on surfaces no more than 6” high to comply with Americans with Disabilities Act (ADA). The bottom flexible transition lip allows for an easy ramp to ground transfer. There is no hardware in the usable ramp area, avoiding any tripping hazard."
