6" Torsion Spring Winding Cone – Left-Hand Wound, 1-1/4" Bore

This winding cone is designed for compatible left-hand-wound torsion springs with a 6-inch inside diameter. Its 1-1/4-inch bore fits a matching torsion shaft, while the winding-bar openings allow the spring to be properly tensioned during installation.

Compatibility

Use only with a left-hand-wound torsion spring measuring 6 inches across the inside diameter and a compatible 1-1/4-inch torsion shaft.

Confirm the spring’s inside diameter, wind direction, wire size and shaft diameter before ordering. This cone is not interchangeable with the 1-inch-bore version or a right-hand-wound winding cone.

For the opposite spring wind, see the 6" Torsion Spring Winding Cone – Right-Hand Wound, 1-1/4" Bore.

If both spring fittings require replacement, consider the 6" Torsion Spring Cone 2-Piece Set – Left-Hand Wound, 1-1/4" Bore.

Installation and Safety

Torsion springs store extreme mechanical energy. Installation and winding should be completed by a trained garage-door professional using properly sized winding bars.

Never use screwdrivers, punches or improvised rods as winding tools. Verify that the cone’s set screws securely engage the shaft and inspect the complete counterbalance system before operating the door.
