SSC .2343" × 2.00" ID × 29.00" Torsion Spring – LW – Brown

🇺🇸 Made in USA

This SSC left-wound torsion spring is intended for sectional garage door systems requiring .2343" wire, a 2.00" inside diameter, and a 29.00" relaxed spring-body length. It features coated, oil-tempered wire and is supplied with installed winding and stationary cones.

A properly selected spring works with the rest of the counterbalance assembly to offset the door’s weight throughout its movement. Correct balance supports controlled manual operation and allows the opener to move the door without compensating for an incorrect spring.

Specifications

Construction & What Is Included

The oil-tempered wire is designed for repeated torsional loading during garage door operation. The coating helps protect the wire surface but does not eliminate the effects of moisture, wear, or a demanding environment.

The winding and stationary cones are installed. Cone-to-shaft fit and stationary mounting compatibility must still be verified before installation.

This listing includes one spring with its cones. Companion springs, shafts, drums, cables, bearings, brackets, and installation tools are not included.

Common Uses

Suitable for professional replacement of a matching left-wound spring on a sectional garage door. A technician may also select it as part of a calculated counterbalance combination when servicing a door whose original spring specification needs correction.

Door width, brand, or opener horsepower does not determine the correct spring. Selection must account for actual door weight, height, cable drums, and the complete spring arrangement.

Compatibility & Measurement

Match .2343" wire diameter, 2.00" inside diameter, 29.00" relaxed body length, and left-hand wind.

A brown-coded spring with a different inside diameter or body length is not automatically interchangeable. Each dimension contributes to spring performance, and a substitution must be verified through calculation.

The 29.00" dimension describes the relaxed coil body without cones. It should not be taken from an installed spring under winding tension. Have a qualified technician confirm the measurements safely.

The spring’s 2.00" ID is separate from the torsion shaft diameter. Verify the cone bore, stationary mounting arrangement, bearing compatibility, and available assembly space before ordering.

Brown Identification & Left-Hand Wind

Brown is the wire-size identification color. LW identifies the direction of the spring coil. These markings do not establish a universal door-weight capacity.

The correct wind must match the counterbalance arrangement. A spring’s position on the shaft should not be the only basis for identification, especially on modified or special-layout systems.

Pairing, Cable Drums & Door Modifications

For a two-spring door, have both springs evaluated and confirm their combined performance. Replacing both aging springs may be appropriate, but the engineered pair can use equal or unequal dimensions.

Added insulation, glazing, overlays, replacement sections, or different cable drums may change the door’s requirements. A high-lift or vertical-lift conversion requires application-specific spring calculations rather than reuse of a standard-lift assumption.

Cycle Life & Ongoing Care

The standard minimum rating is 10,000 cycles when the spring is correctly selected. One cycle is one full opening and closing. This is a design rating, not a guaranteed lifespan in years.

Follow the door manufacturer’s inspection and lubrication recommendations. Seek service if the door becomes heavy, uneven, or unusually noisy. Do not attempt to resolve those symptoms by changing spring tension yourself.

Installation & Safety

Professional installation is required. Never loosen loaded winding cones, stationary anchors, cable drums, or bottom cable brackets. Improper handling can release dangerous stored energy.

A qualified technician should use correctly fitting winding bars, inspect cables and supporting hardware, and follow the manufacturer’s procedures. Before returning the door to service, verify balance, cable tracking, and opener safety operation.

Choose this SSC left-wound spring once its exact dimensions and wind match your verified replacement requirements.
