Gardner Spring 37054G Extension Spring 3/8 in Od 10 Lb

Product Description

The GARDNER SPRING 37054G is a zinc-plated extension spring designed to store and release tension energy in light-duty mechanical assemblies. It features a 0.3750 inch outside diameter and a 0.0450 inch wire diameter, with a spring rate of 20.2 pounds per inch. The free length is 1 inch, and the maximum extended length is 1.44 inches. An initial tension of 1.2 pounds keeps the coils closed under no load. With a maximum work load of 10 pounds, this spring suits precision applications where consistent force and compact size are required. Installation is typically performed by mechanical assemblers, maintenance technicians, or tradespeople working on equipment that uses tension spring returns.

The 37054G is suited for light-duty mechanical and industrial applications where a small-profile extension spring is needed to return a component to a neutral position or maintain constant tension. Its compact 1 inch free length and 3/8 inch OD make it appropriate for use in equipment panels, linkages, latches, damper blades, and similar assemblies found in HVAC equipment, control panels, and general mechanical systems. This part is sold in packs of 6, making it practical for service calls or bench stock replenishment.

Key Features

• Compact 1 inch free length and 0.3750 inch OD fits tight mechanical clearances
• Initial tension of 1.2 pounds keeps coils closed without external load
• Maximum work load of 10 pounds suits light-duty return and tensioning applications
• Sold in a package of 6 pieces for efficient stocking and service use

Compatibility

Designed as an OEM-style replacement or service stock extension spring for light-duty mechanical assemblies requiring a 3/8 inch OD spring with a 1 inch free length and 10 pound maximum work load.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the equipment being serviced. Always de-energize or shut down the equipment and relieve any stored mechanical tension before removing or installing springs. Use appropriate spring hooks or installation tools to avoid overstretching the spring beyond its maximum extended length of 1.44 inches, as exceeding this limit can cause permanent deformation or failure. Follow the equipment manufacturer's service documentation for proper hook orientation and attachment points.
