5-7/8" OHD-Style Torsion Spring Winding Cone – Right-Hand-Wound Spring

Replace the winding cone on a compatible 5-7/8-inch OHD-style right-hand-wound torsion spring with this SSC component. The cone provides the winding-bar sockets and set screws required to apply spring tension and secure the spring to the torsion shaft.

Compatibility and Related Parts:

• Matching right-wound stationary cone: SSC 1582

• Opposite-wind winding cone: SSC 1579

• Opposite-wind stationary cone: SSC 1583

• Left-wound 1-1/4" bore winding cone: SSC 1581

The standard-bore 1578 should not be substituted for the 1-1/4-inch-bore 1580. Verify the shaft diameter, spring inside diameter, wire size, wind direction, OHD-style configuration, and existing cone markings before ordering.

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

Spring wind refers to the direction in which the wire is coiled—not simply the side of the door where the spring is installed. Compare the replacement with the original component or the door manufacturer’s specifications.

A large commercial torsion spring stores extreme mechanical energy. Installation and winding should be performed only by a qualified commercial garage door technician using correctly sized winding bars and proper spring-service equipment.

Order SSC 1578 when the application requires a standard-bore OHD-style winding cone for a 5-7/8-inch right-hand-wound torsion spring.
