Gardner Spring E58C-SS Extension Spring 0.5in Od 16.33lb

Product Description

The GARDNER SPRING E58C-SS is a close-wound extension spring designed for mechanical assemblies requiring precise tensile force control. With a 0.5 inch outside diameter and a 0.055 inch wire diameter, this spring delivers a spring rate of 4.29 pounds per inch and a maximum working load of 16.33 pounds. The overall length is 2.75 inches. It is suited for use in light industrial equipment, HVAC linkages, door assemblies, and other mechanical systems where controlled extension force is needed. Licensed mechanics and maintenance technicians are the typical installers.

This extension spring is commonly used in residential and light commercial applications wherever a compact, moderate-load tensile spring is required. Typical installations include equipment access panels, tensioning mechanisms, and linkage assemblies across HVAC, plumbing, and general mechanical systems. Each package includes 3 pieces, making it practical for service calls requiring on-hand spares or matched sets.

Compatibility

Designed as an OEM-style replacement extension spring for light mechanical assemblies requiring a 0.5 inch OD, 2.75 inch length, and 4.29 lb per inch spring rate.

Installation Notes

Extension springs should be installed by a qualified mechanic or technician familiar with spring-loaded assemblies. Always de-energize or relieve tension from the system before removing or installing springs. Use appropriate pliers or spring installation tools to avoid overstretching the spring beyond its maximum working load. Inspect mounting hooks and anchor points for wear or deformation before installation.
