This product is specifically identified for a left-hand-wound spring. Spring wind refers to the direction in which the spring wire is coiled—not simply the side of the door on which the spring appears. Compare the replacement with the original cone and verify the spring wind before ordering.

The package contains one stationary cone only. It does not include a winding cone, torsion spring, shaft, bearing, spring anchor bracket, mounting fasteners, or installation tools.

Confirm the 3-1/2-inch spring inside diameter, maximum wire size, wind direction, cone dimensions, bore, and mounting arrangement. This component should not be substituted solely because another cone appears visually similar.

Torsion springs store dangerous mechanical energy. The spring must be fully de-tensioned before the cone is removed or installed. Service should be performed by a qualified garage door technician with correctly sized winding bars and appropriate spring equipment.
