Gardner Spring V3C-SS Extension Spring 33.97 Lb Max Load

Product Description

The GARDNER SPRING V3C-SS is a stainless steel extension spring designed to store and release tension energy in mechanical assemblies. It has an outside diameter of 0.73 inches, a wire diameter of 0.0915 inches, and a free length of 4.0 inches. At full extension, it reaches a maximum extended length of 6.25 inches and handles a maximum work load of 33.97 pounds. The spring rate is 11.22 pounds per inch, making it predictable and consistent under load. It is suited for use in HVAC equipment linkages, damper actuators, control assemblies, and other mechanical systems where controlled linear tension is required. Installation is performed by technicians and mechanics familiar with spring-loaded components.

This extension spring is commonly used in commercial and residential mechanical systems that require reliable return force or tension between two fixed points. Typical applications include damper blade linkages, access panel latches, counterbalance mechanisms, and equipment door returns. The compact free length of 4.0 inches and the 0.73-inch outside diameter allow it to fit in space-constrained mounting locations. This SKU is packaged in a quantity of 3 pieces per pack, making it practical for service calls that may require multiple replacements or spares on hand.

Installation Notes

Extension springs should be installed by qualified technicians familiar with spring-loaded mechanical systems. De-energize or shut down the equipment fully before removing or installing any spring component to prevent snap-back injury. Use appropriate spring hooks or installation tools to seat the spring ends securely on their mounting points. Inspect hook ends and mounting hardware for wear or deformation before reinstalling or replacing the spring.
