Garage door extension springs are a type of spring system used in garage doors to assist with lifting the door. They are located above the horizontal tracks on either side of the door and provide the necessary tension to lift the door.
One end of the extension spring is attached to the bottom of the door with the pulley and cable system, while the other end is secured to the horizontal garage door track with a heavy-duty S-Hook.
Various weight options available.
*Please note, springs are sold individually and not in pairs*
