SSC .2830" × 1.75" ID × 50.00" Torsion Spring – RW – Light Blue
SSC .2830" × 1.75" ID × 50.00" Torsion Spring – RW – Light Blue
🇺🇸 Made in USA
This SSC right-wound torsion spring is intended for sectional garage door systems requiring .2830" wire, a 1.75" inside diameter, and a 50.00" 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.

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 .2830" wire and 50.00" 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.
Compatibility: Wire Size, ID & Clearance
Confirm .2830" wire diameter, 1.75" inside diameter, 50.00" relaxed body length, and right-hand wind.
This spring is not interchangeable with a .2950" × 1.75" × 50.00" spring simply because its inside diameter and length match. Wire diameter substantially affects spring performance.
A .2830" spring with a 2.00" ID is also a different configuration. Any substitution requires a professional calculation rather than a visual comparison.
The 50.00" dimension describes the relaxed coil body, excluding both cones. Have a technician confirm enough shaft space for the complete assembly and the installed operating arrangement. Measurements from a wound spring may not represent its original relaxed length.
The 1.75" ID refers to the coils—not the shaft. Check cone bore, shaft fit, and stationary mounting separately.
Light Blue Identification & Wind Direction
Light blue is the wire-size identification color associated with this .2830" spring. Do not confuse it with the blue identification used for .2625" wire. Paint can fade or be difficult to distinguish, so verify the actual wire diameter.
RW identifies the coil direction. Color does not establish installation side or lifting capacity, and shaft position alone should not be the only basis for choosing wind.
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.
Order this SSC right-wound spring after confirming the .2830" wire, 1.75" ID, exact 50.00" body length, and complete application requirements.
