These oil-tempered steel extension springs are for compatible residential garage doors that are 8 feet high. They replace worn or broken springs and are sold as a matched pair.
Each spring is 27 inches relaxed and stretches up to 48 inches. The clipped ends connect to the door's pulley and spring hardware, and the springs help counterbalance the weight of the door.
Springs are rated by the pair. Choose the pair that matches the total verified weight of the door. For example, a 100 lb. door needs one pair rated for 100 lbs., not two separate springs each rated for 100 lbs.
