Gardner Spring E20C Extension Spring 0.312 in Od 2.61 Lb

Product Description

The GARDNER SPRING E20C is a steel extension spring designed to store and release energy under tensile load. With an outside diameter of 0.312 inches, a wire diameter of 0.0286 inches, and a spring rate of 0.63 lb/in, this spring provides consistent, controlled resistance across its travel range. The overall free length is 2.5 inches, and the maximum extended length is 5.92 inches. A zinc-plated finish protects against corrosion in typical service environments. The cross-over end style allows straightforward hook attachment during installation. This spring is sized for light-duty mechanical assemblies encountered across HVAC, refrigeration, and general trade equipment service.

The E20C is suited for applications requiring a compact, low-load extension spring in mechanical linkages, access panels, damper assemblies, and similar light-duty mechanisms. The maximum work load of 2.61 lb makes it appropriate for counterbalancing small components or maintaining tension in control linkages. Packaged in quantities of 12, this spring is a practical stocking item for service technicians and parts rooms that regularly handle mechanical repairs across multiple equipment types.

Compatibility

Designed as an OEM-style replacement or service stock extension spring for light-duty mechanical assemblies in HVAC, refrigeration, and general trade equipment where a 0.312 inch OD cross-over end spring is specified.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the equipment being serviced. Always de-energize equipment and release any stored mechanical tension before removing or installing springs. Use appropriate pliers or spring hooks rated for the load; never overstretch the spring beyond its maximum extended length of 5.92 inches, as this can permanently deform the coils and compromise load capacity. Verify end hook orientation and attachment point integrity before returning the assembly to service.
