Product Description

This left-wind garage door torsion spring is a commercial-grade long-length torsion spring designed for sectional overhead doors requiring a .2187 wire size, 2.00-inch inside diameter, and 120-inch spring length. Manufactured from premium oil-tempered spring steel with a protective coating, this spring delivers consistent torque output, reliable counterbalance performance, and extended service life in demanding residential, commercial, and industrial applications.

The spring functions as a critical component of the garage door counterbalance system, storing rotational energy as the door closes and releasing that energy during opening. Proper spring balance reduces stress on operators, shafts, lift cables, bearings, drums, and other hardware throughout the system. Long-length springs are commonly selected when specific torque requirements or extended cycle performance are needed.

How This Part Fits Into the Garage Door System

The torsion spring serves as the primary lifting force within the garage door counterbalance system. Mounted on the torsion shaft above the door opening, it stores energy when the door closes and releases that energy when the door opens.

This spring works directly with:

• Torsion shaft
• Cable drums
• Lift cables
• Center support brackets
• Bearing assemblies
• Commercial operators
• Jackshaft operators

A properly sized torsion spring allows the door to remain balanced throughout its travel, reducing operator wear, minimizing cable stress, improving safety, and extending the life of rollers, hinges, bearings, and drive components. Long-length springs are often used when specific torque values must be achieved without increasing wire size.
