SSC .2437 x 2″ ID x 31.5″ Torsion Spring – Left Wind – Green
SSC .2437 x 2″ ID x 31.5″ Torsion Spring – Left Wind – Green
🇺🇸 Made in USA
Manufactured by Service Spring Corporation (SSC), this .2437″ wire x 2″ inside diameter x 31.5″ left-wind torsion spring is a replacement component for a correctly matched sectional door counterbalance system.
Supplied with winding and stationary cones installed, the spring uses coated, oil-tempered wire. Its dimensions and winding direction must match the existing engineered spring arrangement or a professionally calculated replacement.
Features & Benefits
-
.2437″ wire diameter with green wire-size identification.
-
2″ inside diameter.
-
31.5″ unwound spring-body length.
-
Left-wind configuration.
-
Winding and stationary cones installed.
-
Coated, oil-tempered wire.
-
Stenciled and color-coded for identification.

Common Uses
For replacing a matching left-wind torsion spring on a compatible sectional overhead door. Door weight and height, cable-drum geometry, track arrangement, and any companion spring determine the correct application.
This spring does not have a universal lifting-capacity rating independent of the system in which it operates.
Compatibility & Selection
Confirm .2437″ wire, 2″ inside diameter, 31.5″ unwound body length, and left wind. Verify shaft and cone fit, stationary-cone mounting, and clearance along the shaft.
Do not round the wire diameter to .250″ or choose a spring based on an approximate measurement. Small differences in wire diameter can substantially change spring performance.
The green marking is an identification aid. It does not replace measurements or establish compatibility with every door using a green-marked spring.
Pairing & Higher-Cycle Options
In a two-spring assembly, this spring must work with its companion to provide the correct combined torque. The proper companion may be the same size with opposite winding or a different size specified by the system design.
If one aging spring fails, have both springs evaluated. A higher-cycle replacement requires an engineered alternative that maintains the required operating characteristics and fits the available shaft space.
High-lift tracks, vertical-lift operation, and changes to cable drums require a separate spring calculation.
Installation & Safety
Torsion springs store dangerous mechanical energy. Replacement should be performed by a trained garage door technician using proper tools and procedures.
Do not loosen loaded spring cones, cable drums, cables, or bottom brackets. After installation, verify manual balance throughout travel, proper cable seating, hardware clearances, and opener safety reversal.
Order this SSC left-wind spring after confirming its exact dimensions and system fit. Contact us before purchasing if any measurement or compatibility detail is uncertain.
