6" Garage Door Torsion Spring Winding Cone – Right-Hand Wound, 1-1/4" Bore

Replace the winding cone on a compatible 6-inch right-hand-wound torsion spring with this SSC heavy-duty cone. Its 1-1/4-inch bore fits the specified torsion shaft, while the winding-bar sockets and set screws allow the spring’s required torque to be applied and secured.

This cone is specifically manufactured for a right-hand-wound spring and a 1-1/4-inch shaft. Do not confuse it with the standard 1-inch-bore version or the corresponding cone for a left-hand-wound spring.

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

Confirm the spring’s 6-inch inside diameter, right-hand wind, wire size, 1-1/4-inch shaft, set-screw arrangement, and existing cone dimensions before ordering. Never enlarge, reduce, or otherwise modify the cone bore to fit a different shaft.

A winding cone transfers substantial force between the spring and torsion shaft. Installation and spring winding should be performed only by a qualified commercial garage door technician using solid, correctly sized winding bars.

Order SSC 143 when your approved assembly requires one 1-1/4-inch-bore winding cone for a compatible 6-inch right-hand-wound torsion spring.
