This listing includes one winding cone only. The stationary cone, torsion spring, shaft, center bearing, spring anchor bracket, mounting hardware, and winding bars are not included.

Although described as universal, this cone is not automatically compatible with every 5-1/4-inch spring assembly. Verify the spring’s actual inside diameter, wire size, torsion-shaft diameter, cone bore, set-screw arrangement, and available installation clearance before ordering.

The 5-1/4-inch measurement refers to the spring’s inside diameter—not the shaft diameter or outside diameter of the spring. Compare the replacement cone with the original part whenever possible.

Torsion springs store extreme mechanical energy. Installation and winding should be performed only by a qualified commercial garage door technician using solid, correctly sized winding bars and approved spring-service procedures.

Order SSC 141U when the application requires one universal winding cone for a compatible 5-1/4-inch ID torsion spring with wire no larger than .4375 inch.
