The Outback ST's self-tensioning tie-down system, automatic stowing mechanism, and 300lb lifting capacity make transporting your mid-wheel drive power chair a breeze. This lift easily installs onto vehicles approved for a Class III hitch. Operation is easy with its large magnetic switches. VMI utilizes two stabilizing pins to prevent rattle and sway when driving. There is no other self-tensioning tie-down system that is so reliable and so secure.
