AmeriGlide's Universal Outside Lift 350 XL is made especially for owners of the largest scooters and power wheelchairs, including scooters with 48-inch wheelbases. Locking retractors hold your mobility device in place, and this is the only manual function of the lift - everything else is automated. Due to the size of this lift, it is only compatible with Class III hitches. An optional swing-away arm can be added to allow users access to their trunk or rear hatch without needing to dismantle the lift.
