Product Description
This left-wind garage door torsion spring is a heavy-duty long-length torsion spring designed for commercial, industrial, and specialty overhead door systems requiring a .2730 wire size, 2.00-inch inside diameter, and 120-inch spring length. Manufactured from premium oil-tempered spring steel and finished with a protective coating, this spring provides reliable torque output, smooth door operation, and long service life in demanding counterbalance applications.
As a critical component of the garage door counterbalance system, the spring stores energy when the door closes and releases that energy during opening, helping offset door weight and reducing stress on operators, shafts, lift cables, drums, bearings, and other hardware. The extended 120-inch length allows the spring to achieve specific torque requirements while supporting heavy-duty and high-cycle door systems.

The torsion spring is the primary counterbalance component of an overhead door system. Mounted on the torsion shaft above the door opening, it stores rotational energy as the door closes and releases that energy when the door opens.
This spring works together with:
- Torsion shaft
- Cable drums
- Lift cables
- Center support brackets
- Bearing assemblies
- Commercial jackshaft operators
- Commercial trolley operators
A properly sized left-wind torsion spring helps maintain door balance, reduces strain on the operator, improves safety, minimizes wear on cables and bearings, and extends the service life of rollers, hinges, drums, and other system components. In a standard two-spring setup, it is paired with a matching right-wind spring to evenly distribute the lifting load across the shaft.
