Gardner Spring V11C Extension Spring 0.25in Od 4.56lb

Product Description

The GARDNER SPRING V11C is a galvanized steel extension spring designed to store and release tensile energy in light-duty mechanical assemblies. It measures 4 inches in overall length, with a 0.25-inch outside diameter and a 0.0317-inch wire diameter. The spring rate is 1.28 lb/in, the initial tension is 0.90 lb, and the maximum work load is 4.56 lb. At full extension the spring reaches 6.73 inches. The zinc-plated galvanized finish provides corrosion resistance for both indoor and outdoor applications. Mechanical contractors, HVAC technicians, and maintenance professionals working on equipment that requires light tensile spring return mechanisms will find this part useful.

The V11C is suited for residential and light commercial applications where a compact, small-diameter extension spring is needed. Typical install scenarios include HVAC damper linkages, access panel latches, control cabinet mechanisms, and general equipment assemblies that demand precise, repeatable spring return force within a small form factor. This spring ships in a package quantity of six, making it practical for service vehicles and shop stock.

Compatibility

Designed as an OEM-style replacement or service stock extension spring for light-duty mechanical equipment requiring a 0.25-inch OD, 4-inch free-length tensile spring with a 1.28 lb/in spring rate.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the equipment being serviced. Always de-energize and lock out the equipment before replacing any spring component. Use appropriate spring installation tools to avoid overstretching the spring beyond the 6.73-inch maximum extended length, which can permanently set or damage the coils. Inspect attachment hooks and anchor points for wear before installing the new spring.
