Hillman 25 in. x 130 lbs. Yellow Extension Spring with Safety Cables (1-Pack)

Garage door extension springs are mounted along the sides of the garage door or above the horizontal tracks. Extension springs stretch and contract as the door operates to counterbalance the weight of the door. Residential garage doors have two extension springs, one on each side of the door. Commercial doors often have multiple springs installed on each side. Package includes instructions, mounting hardware and warning and safety information. Warning: Incorrect Installation or Door Position Can Cause serious injury or death. See package warnings and enclosed instructions.
