SSC .2187 x 1.75″ ID x 25″ Torsion Spring – Left Wind – White

🇺🇸 Made in USA

Manufactured by Service Spring Corporation (SSC), this .2187″ wire x 1.75″ inside diameter x 25″ left-wind torsion spring is designed for a compatible sectional door counterbalance system requiring these specifications.

This spring features coated, oil-tempered wire and installed winding and stationary cones. Its 25-inch body length is an essential part of the spring specification and must be matched accurately.

Features & Benefits

• .2187″ wire diameter with white wire-size identification.

• 1.75″ inside diameter.

• 25″ unwound spring-body length.

• Left-wind configuration.

• Winding and stationary cones installed.

• Coated, oil-tempered wire.

• Stenciled and color-coded for identification.

• Standard-cycle spring listed for a minimum 10,000-cycle application when correctly selected.

One complete opening and closing counts as one cycle. Actual service life depends on loading, operating turns, maintenance, installation quality, and environmental exposure.

Specifications

Common Uses

For replacing a matching left-wind torsion spring on a compatible sectional overhead door. The correct application depends on measured door weight, height, cable drums, track geometry, and any companion spring.

A shorter spring body does not automatically indicate a lighter-duty application.

Compatibility & Selection

Verify .2187″ wire, 1.75″ inside diameter, 25″ unwound body length, and left wind. Confirm cone compatibility, shaft fit, stationary mounting, and available operating space.

This 25″ spring is not automatically interchangeable with a 27″ spring of the same wire diameter and ID. Different body lengths produce different torque-per-turn characteristics and can change door balance.

White paint is a supporting identification clue, not a substitute for measurement. Wire-size colors may repeat across different sizes, so confirm the actual wire diameter.

Pairing & Replacement Options

On a two-spring system, the pair must deliver the required combined torque. Equal-size opposite-wind pairs are common, but some doors require different spring sizes on the same shaft.

Have the companion spring evaluated when replacing a broken spring, particularly when both were installed together. A higher-cycle option requires a calculated alternative rather than simply adding length.

High-lift, vertical-lift, or different cable drums require a separate assessment of the spring requirements.

Installation & Safety

Torsion-spring installation should be performed by a trained garage door technician using proper winding bars and manufacturer procedures.

Do not attempt to release spring tension just to obtain measurements unless properly trained and equipped. Never loosen loaded cones, drums, cables, or bottom fixtures. Following installation, verify door balance, cable alignment, and opener safety operation.

Order this SSC 25-inch left-wind spring once the exact size and system fit are confirmed. Contact us with measurements and photos if you need help identifying the correct replacement.
