Pusher Springs

Springs installed on the end of the horizontal tracks to keep the lift cables under tension and prevent them from
coming off the drums when closing the door. Recommended for doors larger than 13’ x 13’ (4 x 4 m). Use only with standard lift movement particularly when a jack shaft operator is installed.
