Gardner Spring E45C Extension Spring 0.437in Od 8.01lb

Product Description

The GARDNER SPRING E45C is a steel extension spring designed for applications requiring a controlled tensile return force. It features a 0.437 inch outside diameter, a wire diameter of 0.0475 inches, and a spring rate of 2.8 pounds per inch. The cross-over end style allows for straightforward hook engagement in assemblies where loop alignment is important. At a maximum work load of 8.01 pounds and a maximum extended length of 5.27 inches, this spring suits moderate-load tension applications across mechanical, HVAC, and general industrial equipment. Installation is typically performed by mechanical technicians or maintenance professionals working with equipment that relies on spring-return mechanisms.

This extension spring is suited for use in light-to-moderate tension assemblies found in residential and commercial HVAC equipment, control linkages, door mechanisms, and general mechanical assemblies. Its 3.0 inch overall free length and zinc-plated finish make it appropriate for environments where mild corrosion resistance is needed. The cross-over end configuration is compatible with standard hook and post mounting configurations common in OEM and aftermarket mechanical service applications.

Compatibility

Designed as an OEM-style replacement or service stock extension spring for light-to-moderate load tension applications in mechanical and HVAC equipment assemblies.

Installation Notes

Extension springs store energy under tension and should only be installed or replaced with all connected equipment powered down and de-energized. Use appropriate hand tools and eye protection when stretching or seating the spring, as unexpected release can cause injury. Verify that the replacement spring rate and maximum load match the equipment manufacturer specifications before installation. Consult applicable equipment service documentation for correct mounting orientation and hook engagement depth.
