This anti-rollback device features a pair of brake arms that instantly grip the tires and prevent the chair from rolling backward when a resident attempts to stand. When seated, the brake arms lift off of the tires and the wheelchair functions normally. Alarm models use one 9 V battery (included).

• For 16" - 20" wide chairs
