Gardner Spring E12C Extension Spring 0.25 in Od Zinc-plated

Product Description

The GARDNER SPRING E12C is a zinc-plated steel extension spring designed for light-duty mechanical and industrial applications requiring consistent, reliable tension. With an outside diameter of 0.25 inches and a wire diameter of 0.0286 inches, this spring delivers a spring rate of 1.45 lb/in and supports a maximum work load of 3.37 pounds. The overall free length is 2.25 inches, extending to a maximum of 4.1 inches under load. Cross-over end style ensures straightforward installation and repeatable alignment in close-tolerance assemblies. This spring is suited for use in HVAC equipment, electrical panels, light mechanical linkages, and general trade service applications where a compact extension spring is required.

The E12C is appropriate for residential and light commercial applications where small-format extension springs are needed for actuator arms, damper linkages, door latches, panel covers, or other tension-return mechanisms. The zinc plating provides corrosion resistance suitable for indoor mechanical environments. Sold in a package of 12 pieces, this spring is well suited for service technicians who need on-hand replacements for common light-duty tension spring positions across multiple equipment types.

Installation Notes

Extension springs should be installed and replaced by qualified mechanical or trade service technicians. Always de-energize or shut down the equipment and relieve any existing spring tension before removing or installing tension springs. Use appropriate spring installation tools to avoid overextending the spring beyond the maximum extended length of 4.1 inches, which can cause permanent deformation or failure. Inspect hook and anchor points for wear or damage before installing a replacement spring.
