100 lb. Heavy-Duty Double-Looped Garage Door Extension Spring 2-Pack - TAN, G.A.S. Hardware, Mfr#: ES-100-TAN

The extension springs are an important part of your garage door system that help in easing and securing the opening and closing of the door. By acting as a counterweight, they reduce the pressure on the torsion cable. These springs are equipped with S hooks at both ends, which can be attached to the pulley and safety cable assembly on the garage door and the stationary bracket on the ceiling. This design ensures smooth and safe functioning of the garage door system.
