Gardner Spring 905 Extension Spring 204 Lb 1-7/8 in Od

Product Description

The GARDNER SPRING 905 is a heavy-duty galvanized steel extension spring designed to store and release tensile energy in industrial, mechanical, and trade applications. Built with a 1.875-inch outside diameter and a wire diameter of 0.2437 inches, it delivers a spring rate of 50.01 pounds per inch and a maximum work load of 204 pounds. The overall free length is 8.75 inches, with a maximum extended length of 11.54 inches. This part is installed by mechanical technicians, HVAC service professionals, and maintenance trades working on equipment that requires controlled tensile return force.

The GARDNER SPRING 905 is suited for residential and commercial mechanical systems where a high-load extension spring is required. Typical applications include equipment doors, tensioning assemblies, counterbalance mechanisms, and machine linkages that demand consistent, rated pull force. This spring is sold as a set of 3 pieces per package, making it practical for service calls and small-scale installations requiring matched spring sets.

Compatibility

Designed as an OEM-style replacement or service stock extension spring for mechanical assemblies requiring a 1.875-inch OD, 204-pound-rated steel extension spring.

Installation Notes

Installation should be performed by a qualified technician familiar with spring-loaded mechanical assemblies. Relieve all tension from the existing spring system and de-energize connected equipment before removing or installing any spring. Use appropriate hand tools and eye protection, as extension springs under load can release stored energy rapidly if mishandled. Ensure the replacement spring rate and maximum load rating match the equipment manufacturer specifications before installation.
