Gardner Spring V4C Extension Spring 26.4 Lb Steel

Product Description

The GARDNER SPRING V4C is a steel extension spring rated for a maximum work load of 26.4 pounds and a spring rate of 8.45 lb/in. The spring has an outside diameter of 0.64 inches, an overall free length of 4 inches, and extends to a maximum of 5.87 inches under load. Wire diameter is 0.08 inches, and initial tension is 3.7 pounds. The galvanized, zinc-plated finish provides corrosion resistance for a range of service environments. This spring is suited for mechanical assemblies, equipment, and trade applications where a precise, rated extension spring is required.

The V4C extension spring is used in mechanical systems that require controlled tension and return force. Typical applications include HVAC equipment linkages, damper and valve assemblies, door and panel mechanisms, and general industrial or trade equipment. The spring is packaged in a quantity of 3 per package, making it practical for stocking or multi-unit service jobs. Its compact diameter and moderate load rating make it a common fit for light-to-medium duty mechanical applications in both residential and commercial settings.

Compatibility

Designed as a standard extension spring for use in mechanical assemblies, HVAC linkages, damper systems, and general equipment requiring a 0.64-inch OD, 4-inch free length extension spring with a 26.4-pound maximum load rating.

Installation Notes

Installation is typically performed by qualified mechanical, HVAC, or equipment service technicians. Relieve all tension from the existing spring assembly and power down or de-energize the equipment before removing the old spring. Use appropriate spring hooks or pliers rated for extension spring work to avoid sudden release of stored energy. Verify that the replacement spring load rating and dimensions match the application requirements before installation.
