Spring wind refers to the direction in which the spring wire is coiled. Verify the wind direction from the existing spring and cone markings rather than relying only on the spring’s position on the door.

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

Before ordering, confirm the spring’s 3-1/2-inch inside diameter, right-hand wind, wire size, Raynor-style configuration, cone bore, and set-screw arrangement. Similar-looking cones may have different winding directions, bores, or installation dimensions.

A winding cone is subjected to substantial force when the spring is tensioned. Installation and winding should be performed only by a qualified garage door technician using solid, correctly sized winding bars and proper spring-handling procedures.

Order SSC 138 when the approved application requires one Raynor-style winding cone for a compatible 3-1/2-inch right-hand-wound torsion spring.
