Gardner Spring E27C Extension Spring 4.67 Lb 0.312 in Od

Product Description

The GARDNER SPRING E27C is a zinc-plated steel extension spring designed for light-duty mechanical and industrial applications where consistent, repeatable tension is required. It features a 0.312 inch outside diameter, a 0.0348 inch wire diameter, and a spring rate of 1.82 pounds per inch. The cross-over hook end style provides reliable engagement with standard anchor points without the stress concentration common in side-hook configurations. At a maximum work load of 4.67 pounds and a maximum extended length of 4.53 inches, this spring suits applications demanding precise load control within a compact envelope. Installation is typically performed by mechanical technicians, maintenance professionals, or trade contractors during equipment assembly or repair.

The E27C is suited for residential and commercial mechanical assemblies, HVAC damper linkages, door or panel return mechanisms, and general equipment maintenance applications where a small-diameter extension spring with controlled rate is required. The cross-over end style simplifies hook-to-hook or hook-to-pin installation in confined spaces. It ships in a package quantity of 12, making it practical for stocking on a service van or in a parts room for recurring maintenance work.

Key Features

• Cross-over hook ends for balanced load transfer and reduced stress at the hook
• 0.312 inch outside diameter fits compact mounting configurations
• 1.82 lb/in spring rate provides predictable, linear extension force
• Zinc-plated steel construction resists corrosion in typical indoor mechanical environments
• Maximum extended length of 4.53 inches with an overall free length of 2.5 inches
• Packaged in quantities of 12 for efficient stocking and repeated service calls

Compatibility

Designed as a standard-dimension replacement or stocking extension spring for light-duty mechanical assemblies, HVAC equipment linkages, and general industrial equipment requiring a 0.312 inch OD cross-over hook extension spring.

Installation Notes

De-energize and lock out any equipment before removing or installing tension springs. Wear eye protection when handling extension springs under load, as sudden release can cause injury. Use appropriate hook or pin anchors rated for the spring load. Verify the anchor points and hook geometry match the cross-over end style before applying tension.
