SSC .2343" × 1.75" ID × 28.25" Torsion Spring – RW – Brown

🇺🇸 Made in USA

This SSC right-wound torsion spring is intended for sectional garage door systems requiring .2343" wire, a 1.75" inside diameter, and a 28.25" relaxed spring-body length. It is manufactured from coated, oil-tempered spring wire and supplied with winding and stationary cones installed.

A properly selected spring helps the counterbalance system offset the door’s weight throughout its movement. Correct balance supports controlled manual operation and allows the opener to move a balanced door rather than compensate for an incorrect spring.

Specifications

Construction & Included Components

The oil-tempered wire provides the spring material for repeated torque loading during normal operation. Its protective coating helps protect the surface, but does not make the spring maintenance-free or immune to environmental wear.

Both cones are installed. Their fit must be checked against the torsion shaft and stationary anchor arrangement before installation.

This listing includes one spring with cones. A companion spring, shaft, drums, cables, bearings, mounting brackets, and winding tools are separate components.

Common Applications

For professional replacement of a matching right-wound spring on a sectional garage door or use in a professionally calculated counterbalance combination.

The .2343" wire and 28.25" length do not, by themselves, establish a universal door-weight capacity. Door weight, travel height, cable drum geometry, and the contribution of any companion spring determine the application.

Exact Fit & Measurement Checks

Confirm .2343" wire diameter, 1.75" inside diameter, 28.25" relaxed body length, and right-hand wind.

Do not round the 28.25" length to 28.00" or 29.00". A change in body length changes the spring rate and requires verification against the door’s counterbalance requirements.

This spring is also different from a .2343" spring with a 2.00" ID. Matching wire size alone is not enough to establish interchangeability.

The stated length describes the relaxed coil body, excluding both cones. It is not the overall assembled length or the length of a spring measured while wound on the door. Have a technician verify the original dimensions safely.

The 1.75" ID refers to the spring coils—not the shaft. Check cone bore, shaft fit, stationary mounting, and available assembly space separately.

Brown Identification & Wind Direction

Brown is the wire-size identification color. RW identifies the direction of the spring coil. These are separate characteristics, and neither establishes a universal lifting capacity.

Confirm wind from the actual spring and system specification. Do not choose a spring solely by its position on the shaft, particularly where the door uses a special layout or has been modified.

Spring Pairing, Drums & Lift Configuration

On a two-spring door, have both springs evaluated and confirm the required replacement combination. Replacing both aging springs may be appropriate, but the correct pair may use matching or different dimensions.

Changes to door weight, cable drum model, or lift arrangement require a new sizing review. High-lift and vertical-lift systems must be calculated for their actual drum and travel geometry.

Cycle Life & Ongoing Care

The standard minimum rating is 10,000 cycles in the correct application. One cycle is one full opening and closing. Actual life varies with operating frequency, maintenance, environment, and loading.

Follow the door manufacturer’s inspection and lubrication guidance. Seek service if the door becomes difficult to lift, travels unevenly, or develops abnormal noise. Increasing opener force does not correct an improperly balanced spring system.

Professional Installation & Safety

Installation and tension adjustment must be performed by a qualified garage door technician using proper winding bars and manufacturer procedures.

Never loosen loaded cones, anchors, drums, or bottom cable attachments. Keep a door with a broken spring out of service. After replacement, inspect supporting hardware and verify door balance, cable tracking, and opener safety operation.
