Description:

Roll up door torsion springs counterbalance the weight of the door to make it easy to open and close. They serve the same purpose of counter weights used to balance doors in centuries past and in many doors today.

When torsion springs are wound, they grow in length. Since both ends of the torsion springs on steel rolling doors are secured and cannot move, the spring cannot grow in length. There are two options for fixing this problem. You can stretch the spring yourself with a come-a-long before you secure it to the shaft, or your can purchase pre-stretched springs. This allows the coils to be gapped and to lose most of this gapping when the door closes.

Depending on the application, commercial and industrial doors come in a variety of lifts, including high-lift and vertical-lift.regardless of your spring dimensions, lift system, shaft style, spring system, or number of springs, you can order replacement torsion springs for your commercial or industrial overhead door.
