        Torsion Spring

     Torsion springs are mounted on a metal tube above the door on the wall. The tube has drums on either side to roll up the cable and lift the garage door. the springs un-wind and loose power as the door goes overhead and looses weight. The rate at which this happens is called inch pounds per turn. The IPPT is based on the height of the door, weight of the door, radius of the tracks and radius of the drums. The IPPT has to be within 3% of the required number to have the door work properly and balance throughout its travel. Most manufacturers distribute 10,000 cycle life springs with new garage doors. This means you can raise and lower your door 10,000 times before you can anticipate one or more of your springs to break. Discount Door Co. recommends replacing these 10,000 stock springs with an extended cycle life spring system of  50,000 plus cycles with a Lifetime Warranty.
