Our #36-54 extension springs are available for garage door weights ranging from 90 lbs. to 280 lbs. Garage door extension springs are color coded to distinguish their weights.

To install your replacement springs, one end of the springs is installed with an S-hook to the stationary hangar angle that supports the garage door tracks, while the other end of the springs hooks to a safety cable-and-pulley assembly that connects to the garage door. When the garage door is in the open position, the initial spring tension holds it in place on the horizontal track.

The pull weight of an extension spring is determined by the color code found on the end of the spring. Once you know that, measure the height of the door. If you cannot determine the color code for the springs, you must weigh the door.

The Door and Access Systems Manufacturers Association (DASMA) has established color codes for extension springs by weight.
