Gardner Spring E3C Extension Spring 0.187in Od 2.33lb

Product Description

The GARDNER SPRING E3C is a small-diameter extension spring designed for light-duty tensioning applications across mechanical assemblies, equipment, and industrial components. It features a 0.187-inch outside diameter, a 0.023-inch wire diameter, and a spring rate of 1.56 pounds per inch. The E3C measures 1.75 inches in overall free length and extends to a maximum of 2.91 inches under a peak load of 2.33 pounds. This spring is typically installed by mechanical technicians, maintenance professionals, and assemblers working on precision equipment or light mechanical linkages where consistent tension and return force are required.

The E3C suits applications requiring a compact, low-force extension spring in tight spaces. Common use cases include door latches, light machinery, control linkages, and equipment panels in residential and commercial service environments. Its small wire diameter and modest load rating make it appropriate for applications where fine tension control is needed without excessive force. Sold in a package quantity of 12, it suits both single-unit repairs and small-batch production or maintenance kits.

Compatibility

Designed as a standard-form extension spring suitable for light mechanical assemblies, control linkages, latches, and similar tensioning applications where a 0.187-inch OD, 1.75-inch free-length spring meets design requirements.

Installation Notes

Extension springs should be installed by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. De-energize or lock out any powered equipment before removing or installing springs to prevent unexpected movement. Use appropriate hook or loop engagement tools to avoid overstretching the spring beyond its maximum extended length of 2.91 inches, which can cause permanent deformation. Inspect hook ends for proper seating after installation to confirm secure retention.
