Safe-t mate, a name that has been trusted by thousands of facilities nationwide since 1998, has redesigned our acclaimed wheelchair anti-rollback device. Like the original, the SM2-2 prevents a wheelchair from rolling back by grabbing the tires as the user attempts to sit or stand. However, the use of high strength plastics and robotic welding has allowed us to add more user-friendly features without increasing the weight or cost! The result, the SM2-2 fits even more chairs, has greater adjustability and increased comfort. Take a look!
