Push-Down Spring Bumper
For standard lift doors with jackshaft operators.
The springs compress as the door reaches the open position. From this position the springs push the door down to prevent the cables from coming off the drums when the operator starts the down cycle.
Total length: 27"
15" compression at approximately 10lbs/in
12 gauge bracket for use with 3/8" bolts
2" rubber bumper
