The black color helps identify this as the left-hand-wound version. Color should not be the only method used to determine compatibility; verify the direction of the spring coils and compare the replacement components with the original cones.

This listing includes the two cones only. The torsion spring, shaft, center bearing, spring anchor bracket, mounting fasteners, and winding bars are not included.

Before ordering, confirm the spring’s 3-3/8-inch inside diameter, left-hand wind, wire size, shaft requirements, cone bore, and mounting configuration. Do not use this set with wire exceeding the published .375-inch maximum.

Installing cones and winding a torsion spring are hazardous procedures that require specialized tools and experience. Installation should be performed by a qualified garage door technician using correctly sized winding bars.

Order SSC 338L when your approved spring assembly requires a black, left-hand-wound two-piece universal cone set for a 3-3/8-inch ID torsion spring.
