Gardner Spring 37056G Extension Spring 10 Lb 3/8 in Od

Product Description

The GARDNER SPRING 37056G is a zinc-plated steel extension spring rated for a maximum work load of 10 pounds and a spring rate of 3.2 pounds per inch. The outside diameter measures 0.375 inches, the free length is 3 inches, and the maximum extended length is 5.75 inches. Wire diameter is 0.045 inches, with an initial tension of 1.2 pounds. This spring is sold in a package of 6 pieces and is suitable for light-duty mechanical assemblies, tooling fixtures, and equipment where a reliable return force is required.

The 37056G is appropriate for use in residential and commercial light-mechanical applications including appliance assemblies, HVAC linkage systems, door return mechanisms, and general-purpose industrial equipment. The zinc-plated finish provides basic corrosion resistance, making it suitable for indoor environments or protected enclosures where mild moisture exposure may occur. Technicians sourcing a small-quantity extension spring with precise load and length specifications will find this unit dimensionally consistent for direct replacement or original assembly use.

Compatibility

Designed as a standard extension spring for light-duty mechanical and equipment assemblies requiring a 3/8-inch OD spring with a 10-pound maximum load rating and 5.75-inch maximum extended length.

Installation Notes

Extension springs should be installed by a qualified technician familiar with spring-loaded mechanical assemblies. Relieve all tension from the assembly and isolate or de-energize any powered components before removing or installing the spring. Use appropriate hand tools and eye protection, as extension springs under load can release energy rapidly if mishandled. Verify that hook engagement points are fully seated and free of deformation before returning the assembly to service.
