Gardner Spring 414C Extension Spring 0.25 in Od 4.56 Lb

Product Description

The GARDNER SPRING 414C is a steel extension spring designed to store and release energy under tension in mechanical assemblies and equipment maintenance applications. It features a 0.25 inch outside diameter, a maximum work load of 4.56 pounds, and a spring rate of 0.81 lb/in, making it well-suited for light-duty tensioning tasks. The wire diameter is 0.0317 inches and the spring carries a zinc-plated finish for corrosion resistance. Double loop ends provide secure attachment points in service assemblies. Technicians in HVAC, refrigeration, and general mechanical trades routinely stock small-format extension springs like the 414C for damper linkages, access panel latches, and equipment hardware repairs.

This extension spring is appropriate for use in residential and light commercial mechanical systems where a compact, low-force tensioning component is required. Typical applications include HVAC damper return mechanisms, control linkage tensioning, door or panel latch assemblies, and general equipment hardware. The 6.0 inch overall length and 4.56 inch maximum extended length accommodate a range of mounting spans without modification. The zinc-plated steel construction suits indoor and protected outdoor installations where light corrosion resistance is needed.

Key Features

• 0.25 inch outside diameter with 0.0317 inch wire diameter for compact light-duty tensioning
• 4.56 lb maximum work load and 0.81 lb/in spring rate for controlled, predictable tension
• Double loop end type provides secure, straightforward attachment to hooks or pins
• Zinc-plated steel finish offers corrosion resistance in typical indoor mechanical environments
• 6.0 inch overall length with 4.56 inch maximum extended length suits common damper and linkage spans

Compatibility

Designed as an OEM-style replacement extension spring for light-duty mechanical assemblies requiring a 0.25 inch OD, double loop end configuration with a maximum work load of 4.56 pounds.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the host equipment. Always de-energize or shut down the associated system before replacing mechanical hardware components. Verify that the replacement spring rate and maximum load rating match the original specification before installation. Overstretching beyond the maximum extended length of 4.56 inches can permanently deform the spring and must be avoided.
