SSC .2437" × 2.00" ID × 28.25" Torsion Spring – LW – Green

🇺🇸 Made in USA

The Service Spring Corp .2437" × 2.00" ID × 28.25" left-wind torsion spring is a replacement spring for garage door counterbalance systems specified for these exact dimensions and winding direction. It is manufactured from coated, oil-tempered wire and supplied with winding and stationary cones installed.

The spring works through the torsion shaft and cable drum assembly to help offset the weight of the door. Correct selection supports balanced travel and appropriate opener operation. Green wire-size identification corresponds to .2437" wire, but the full specification must be checked before purchase.

Specifications

Construction & Included Components

Oil-tempered spring wire provides the material used to store and release energy during door operation. Its protective coating helps protect the wire surface, while appropriate lubrication and inspection remain part of maintaining the assembly.

The installed winding cone provides the tensioning connection, and the stationary cone provides the fixed anchoring connection. The supplied cones must be compatible with the intended shaft and mounting hardware.

This listing includes one spring with cones. Lift cables, cable drums, bearings, support brackets, torsion shaft, and service tools are separate from this spring assembly.

Common Applications

Intended for professional replacement on sectional garage door systems requiring a .2437" wire × 2.00" inside diameter × 28.25" body length, left-wind spring.

The correct spring cannot be established from opener horsepower, door width, or panel appearance alone. Actual door weight and the lift hardware determine the counterbalance requirement. If the door was previously difficult to balance, the installer should confirm the original specification before duplicating it.

Compatibility & Measurement

Match wire diameter, inside diameter, relaxed spring body length, and wind direction. The 28.25" length describes the coil body without the winding and stationary cones, measured in the fully relaxed condition.

The 2.00" inside diameter refers to the opening through the spring coils, not the shaft diameter. Confirm shaft and cone fit, stationary mounting, and adequate operating clearance separately.

A .2437" × 2.00" ID spring measuring 31.50" or 34.00" is not automatically interchangeable with this 28.25" version. The length difference changes spring characteristics and requires evaluation against the door’s torque and travel requirements.

Wind Direction & Color Identification

Left wind describes the direction of the coils. The correct installation position depends on the torsion system’s arrangement, so location alone should not be used to identify wind.

Green is the torsion spring wire-size code for .2437" wire. It is not a universal lifting-capacity rating. Faded, repainted, or missing markings make direct dimensional verification especially important.

Spring Pairing & Door Configuration

For a two-spring assembly, both springs should be assessed together. Their combined output must match the door’s counterbalance requirements, and the companion spring’s age and condition should be considered when deciding whether to replace both.

Some correctly designed systems use springs with different dimensions. Door weight, height, cable drum geometry, and lift configuration determine the appropriate pairing. Standard-lift, high-lift, and vertical-lift applications require calculations suited to their respective arrangements.

Cycle Life & Maintenance

The listed minimum rating is 10,000 cycles in the correct application. A cycle consists of one complete opening and closing; the rating does not promise a fixed calendar lifespan.

Follow manufacturer recommendations for maintenance and lubrication. Uneven travel, unusual noise, or a door that becomes heavy should prompt service. Increasing opener force does not correct a spring balance problem.

Professional Installation & Safety

Installation, removal, and tensioning should be performed by a qualified garage door professional. Never loosen loaded cones, spring anchors, cable drums, or bottom cable brackets.

After replacement, the technician should inspect the surrounding hardware and cables, check door balance throughout travel, and verify opener safety operation before returning the door to service.
