Gardner Spring E30C Extension Spring 0.375 in Od 3.8 Lb

Product Description

The GARDNER SPRING E30C is a steel extension spring designed to store and release energy under tensile load in mechanical assemblies and industrial equipment. It features a 0.375-inch outside diameter, a wire diameter of 0.0348 inches, and a maximum work load of 3.8 pounds. The spring rate is 1.88 pounds per inch, allowing predictable deflection characteristics for consistent performance. The zinc-plated finish provides corrosion resistance suitable for general-purpose applications. Cross-over ends allow for straightforward loop attachment and secure hook engagement. Licensed tradespeople and mechanical technicians install this spring in a wide range of equipment requiring controlled tension return force.

This extension spring is suited for residential and light commercial mechanical applications where controlled return tension is needed. Typical installations include HVAC linkage assemblies, damper actuators, enclosure latches, industrial machinery, and general mechanical equipment requiring a compact, low-profile tension spring. The 1.75-inch overall free length and 3.44-inch maximum extended length make it a practical fit for space-constrained assemblies. It is sold in packages of 12 units, making it appropriate for service stock or multi-unit repair jobs.

Compatibility

Designed as a general-purpose extension spring for mechanical assemblies requiring a 0.375-inch OD cross-over end configuration with a 1.88 lb/in spring rate and up to 3.8 pounds maximum work load.

Installation Notes

Installation is typically performed by mechanical technicians or trained service professionals working on equipment with active tension-loaded assemblies. Relieve all stored tension and de-energize any powered components before removing or installing springs. Use appropriate spring installation tools to avoid overextending the spring beyond its 3.44-inch maximum extended length, which can cause permanent deformation. Inspect mounting hooks and anchor points for wear or damage before installing a replacement spring.
