SSC .2950" × 1.75" ID × 50.00" Torsion Spring – RW – White
SSC .2950" × 1.75" ID × 50.00" Torsion Spring – RW – White
🇺🇸 Made in USA
Replace a matching garage door counterbalance spring with this SSC right-wound torsion spring. It combines .2950" wire, a 1.75" inside diameter, and a 50.00" relaxed spring-body length, with winding and stationary cones installed.
The spring is manufactured from coated, oil-tempered wire for use in a correctly sized counterbalance assembly. Its larger wire diameter does not, by itself, establish a lifting capacity or make it a suitable upgrade for a different spring. Correct selection is essential for proper balance throughout the door’s travel.

Construction & Included Fittings
Oil-tempered wire provides the spring material for repeated torque loading during normal door operation. The coating helps protect its surface, although appropriate inspection and maintenance remain necessary.
Both cones are installed. A technician must verify their fit with the intended shaft and stationary anchor arrangement before installation.
This listing includes one spring with cones. A companion spring, shaft, cable drums, cables, bearings, 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.
Actual door weight, travel height, cable drum geometry, and the complete spring arrangement determine suitability. Do not select this spring solely because its wire appears heavier or its body is longer than the existing spring.
Compatibility: Dimensions & Available Space
Confirm .2950" wire diameter, 1.75" inside diameter, 50.00" relaxed body length, and right-hand wind.
The 50.00" dimension covers only the relaxed coil body. Both cones and the installed operating arrangement require additional space. Have a technician verify sufficient room on the shaft and clearance from nearby hardware.
The 1.75" ID refers to the spring coils, not the torsion shaft. Cone bore, shaft fit, stationary mounting, and available assembly space are separate compatibility checks.
Changing the inside diameter or body length changes spring performance. Any substitution requires calculation. Measurements taken from an installed spring under winding tension may also differ from its original relaxed dimensions.
White Color Code: Verify the Actual Wire
White is the wire-size identification color for this spring, but color codes repeat across wire sizes. This .2950" spring must not be confused with a white-coded .2187" spring.
Confirm the wire by measurement and the product specification. RW identifies the coil direction. The white marking does not establish installation side or door-weight capacity.
Pairing, Drums & Lift Configuration
On a two-spring door, have both springs evaluated and verify the complete replacement combination. Springs with similar age and usage may warrant replacement together, but the engineered pair can use matching or different dimensions.
Added door weight, replacement sections, different drums, or lift conversions can change the required selection. High-lift and vertical-lift applications require calculations based on their actual drum and travel geometry.
Cycle Life & Maintenance
The standard minimum rating is 10,000 cycles in a correctly selected application. One cycle equals one complete opening and closing. Actual service life depends on loading, usage frequency, environment, and maintenance.
Follow the door manufacturer’s inspection and lubrication guidance. Arrange service if the door becomes heavy, operates unevenly, or develops unusual noise. Do not increase opener force to mask a balance problem.
Professional Installation & Safety
Torsion spring installation and adjustment must be performed by a qualified garage door technician. Never loosen loaded cones, anchors, cable drums, or bottom cable brackets, and never use improvised winding tools.
Keep a door with a broken spring out of service. After replacement, inspect supporting hardware and verify balance, cable operation, and opener safety functions.
Order this SSC right-wound spring after confirming the .2950" wire, 1.75" ID, 50.00" relaxed length, and complete application requirements.
