Gardner Spring E48C Extension Spring 8.02 Lb 0.437 in Od

Product Description

The GARDNER SPRING E48C is a steel extension spring designed to store and release energy under tensile load in mechanical assemblies, tooling, and equipment applications. With a maximum work load of 8.02 pounds and a spring rate of 2.06 pounds per inch, it delivers consistent, predictable resistance across its extension range. The outside diameter measures 0.437 inches, wire diameter is 0.0475 inches, and the overall free length is 3.75 inches. A zinc-plated finish provides corrosion resistance in light-duty service environments. Licensed tradespeople and maintenance technicians working on mechanical systems will find this spring suited to applications requiring controlled return force in compact assemblies.

This extension spring is used in residential and commercial mechanical applications where a compact, cross-over end style is required for hook or loop attachment points. The cross-over end configuration allows for straightforward loop attachment to pins, hooks, or anchor points in assemblies with limited clearance. Typical install scenarios include equipment linkages, door assemblies, valve actuators, and general industrial mechanisms where a zinc-plated steel spring of this load class is specified. It is packaged in a quantity of 12 pieces per pack, making it practical for service stock and light production use.

Compatibility

Designed as an OEM-style replacement or service stock extension spring for mechanical assemblies requiring a cross-over end style spring with a 0.437 inch outside diameter and 8.02 pound maximum load rating.

Installation Notes

Installation is performed by mechanical technicians or maintenance professionals familiar with spring-loaded assemblies. Before servicing any spring-loaded mechanism, de-energize or de-tension the assembly fully and follow all applicable lockout and tagout procedures. Use appropriate pliers or spring installation tools to seat the cross-over ends onto anchor points without overextending the spring beyond its rated maximum extended length of 6.85 inches. Never stretch an extension spring beyond its rated travel, as permanent deformation or failure can result.
