Gardner Spring E35C Extension Spring 3.8 Lb Max Load

Product Description

The GARDNER SPRING E35C is a zinc-plated steel extension spring designed to deliver controlled tension across a wide range of light-duty mechanical applications. It has an outside diameter of 0.375 inches, a free length of 3.0 inches, and a maximum extended length of 6.84 inches. The wire diameter is 0.0348 inches, and the spring rate is 0.82 lb/in, supporting a maximum work load of 3.8 pounds. The cross-over end style allows for straightforward hook engagement in standard spring anchor points. This part is typically installed by maintenance technicians, equipment assemblers, and trade professionals working on mechanical assemblies that require repeatable tension and return force.

The E35C is suited for residential and light commercial mechanical assemblies where a compact, consistent-rate extension spring is required. Common applications include HVAC equipment linkages, damper return mechanisms, small appliance assemblies, and general industrial hardware. The zinc-plated finish provides a basic level of corrosion resistance appropriate for indoor environments. This item is sold in a package quantity of three, making it practical for service kits and bench stock replenishment.

Installation Notes

Installation is typically performed by maintenance technicians or mechanical assemblers using standard hand tools. Always de-energize or de-pressurize the host equipment before removing or installing any spring component. Verify that the replacement spring rate and maximum load rating match the original equipment specification before installation. Do not stretch the spring beyond its rated maximum extended length of 6.84 inches, as overextension can cause permanent deformation or failure.
