A duplex system uses a specialized spring arrangement and requires components specifically matched to that configuration. This short-ear cone should not be substituted for a standard stationary cone, a long-ear cone, or the corresponding left-wound version.
The package includes one right-wound short-ear duplex stationary cone only. It does not include the spring, winding cone, companion cone, shaft, spring anchor bracket, bearings, fasteners, or installation tools.
Before ordering, verify the 3-3/4-inch spring inside diameter, right-hand wind, maximum wire size, duplex configuration, ear dimensions, bore, and mounting pattern. Compare all critical dimensions with the original cone or the door manufacturer’s spring specifications.
Duplex torsion-spring assemblies contain substantial stored energy and require specialized knowledge to disassemble and rebuild safely. Installation should be performed only by a qualified commercial garage door technician.
Order SSC 193593 when the approved application calls for one 3-3/4-inch short-ear duplex stationary cone for a right-hand-wound spring.
