SSC .2730" × 2.00" ID × 45.00" Torsion Spring – LW – Orange

🇺🇸 Made in USA

This Service Spring Corp torsion spring combines .2730" wire diameter, a 2.00" inside diameter, a 45.00" spring body length, and left-hand wind. It is supplied with installed winding and stationary cones for professional replacement in compatible garage door counterbalance systems.

The spring’s purpose is to help offset door weight through the torsion shaft and cable drum assembly. Correct selection supports balanced movement throughout travel and allows the opener to operate a properly counterbalanced door. Coated, oil-tempered wire provides the working spring body, with orange identification corresponding to the .2730" wire size.

Specifications

Construction & Included Components

The oil-tempered spring wire stores and releases energy as the door moves. Its protective coating helps protect the wire surface, while regular inspection and manufacturer-recommended maintenance remain necessary.

Installed winding and stationary cones provide the spring’s tensioning and anchoring interfaces. This listing supplies one spring with cones; the shaft, cables, cable drums, bearings, mounting brackets, and service tools are separate.

The cones extend beyond the listed 45.00" coil body length. The installer must account for the assembled spring and its operating requirements when checking available space.

Common Applications

Suitable for professional replacement where the approved specification calls for a .2730" × 2.00" ID × 45.00" left-wind spring.

Wire diameter alone does not establish lifting capacity. Door weight, height, drum design, and the complete spring arrangement determine suitability. Changes to glazing, reinforcement, insulation, or door sections can alter the required counterbalance and should be considered before duplicating an existing spring.

Compatibility & Measurement

Verify wire size, inside diameter, relaxed body length, and wind direction. The 45.00" measurement refers to the coil body without its cones, measured in the fully relaxed condition by a qualified technician.

The 2.00" inside diameter describes the coil opening rather than the shaft size. Cone compatibility, anchor mounting, shaft fit, and adequate operating clearance require separate confirmation.

A .2730" × 1.75" ID × 45.00" spring is not equivalent to this 2.00" ID version. Matching wire diameter and length does not compensate for a different coil diameter; any substitution requires a professional spring calculation.

Wind Direction & Color Identification

Left wind identifies coil direction and must match the intended position within the actual torsion assembly. Do not choose winding direction solely from the side of the door where a spring appears.

Orange is the wire-size color code for .2730" torsion spring wire. It does not identify a door weight rating, a universal winding setting, or compatibility with other orange-marked hardware.

Spring Pairing & Lift Requirements

For a two-spring system, both springs must be considered together. The technician should inspect the companion spring and determine whether replacing both is appropriate based on condition, age, and the intended combined output.

Door travel height, cable drums, and standard-, high-, or vertical-lift geometry affect selection. A longer spring is not automatically an extended-cycle upgrade; a valid conversion must satisfy the door’s torque and travel requirements.

Cycle Life & Maintenance

The listed minimum rating is 10,000 cycles in the correct application. Each complete opening and closing counts as one cycle. Actual service duration varies with use, environmental exposure, and system condition.

Follow manufacturer lubrication guidance. Heavy operation, uneven movement, or unusual noise should be investigated rather than compensated for with additional opener force.

Professional Installation & Safety

Torsion spring work requires a qualified garage door professional. Never loosen loaded cones, anchors, cable drums, or bottom cable brackets.

After installation, the technician should inspect cables and bearings, confirm secure mounting, and verify door balance and opener safety operation.
