Gardner Spring E15C Extension Spring 0.312 in Od Cross-over

Product Description

The GARDNER SPRING E15C is a steel extension spring designed for applications requiring a controlled return force and precise load characteristics. With an outside diameter of 0.312 inches and a wire diameter of 0.0286 inches, this spring delivers a spring rate of 1.91 lb/in and a maximum work load of 2.62 pounds. The overall free length is 1.25 inches, and the maximum extended length is 2.4 inches. The zinc-plated finish provides corrosion resistance for use in light-duty mechanical assemblies. Cross-over style ends allow for straightforward loop attachment in a wide range of fastening and tensioning configurations. HVAC technicians, equipment assemblers, and maintenance professionals commonly specify springs of this type for linkage, latch, and tensioning applications.

The E15C suits residential and light commercial mechanical assemblies where a compact, small-diameter extension spring is needed. Typical uses include HVAC damper linkages, control panel latches, small appliance tensioning mechanisms, and general equipment repair. The cross-over end style supports in-line load transfer and is compatible with standard hook and pin mounting points. Sold in packages of 12, this spring is appropriate for technicians who need a reliable stock quantity for service or production use.

Installation Notes

Installation is performed by qualified technicians familiar with mechanical spring assemblies. De-energize and lock out any equipment before replacing or installing extension springs. Use appropriate pliers or spring hooks to seat the cross-over ends onto mounting pins or hooks without overextending the spring beyond its maximum extended length of 2.4 inches. Exceeding the maximum extended length may permanently deform the spring and reduce load capacity.
