Gardner Spring E47C Extension Spring 8.02 Lb 0.437 in Od

Product Description

The GARDNER SPRING E47C is a zinc-plated steel extension spring designed for applications requiring controlled tensile resistance. With a spring rate of 2.2 lb/in and a maximum work load of 8.02 lb, it delivers consistent, repeatable performance across mechanical and industrial assembly applications. The wire diameter is 0.0475 inches, and the outside diameter measures 0.437 inches. It features a cross-over end style, which provides secure loop engagement and even load distribution. HVAC technicians, mechanical contractors, and industrial maintenance professionals will encounter this spring in damper linkages, access panel latches, tension mechanisms, and similar light-duty spring-loaded assemblies.

This extension spring is suited to residential and light commercial mechanical systems where a compact, reliable tension component is needed. Its overall free length of 3.5 inches and maximum extended length of 6.39 inches make it appropriate for installations with limited travel range. The zinc-plated finish provides basic corrosion resistance for indoor or sheltered environments. It is packaged in quantities of 12, making it practical for service shops and contractors maintaining stock for recurring repair and replacement needs.

Key Features

• Cross-over end style for secure, balanced loop engagement
• 2.2 lb/in spring rate for consistent, predictable tensile load response
• Zinc-plated steel construction for corrosion resistance in sheltered applications
• Compact 3.5-inch free length with 6.39-inch maximum extended length
• 0.0475-inch wire diameter for light-duty tensile applications
• Packaged 12 pieces per unit for convenient shop and field stocking

Compatibility

Designed as an OEM-style replacement extension spring for light-duty mechanical assemblies requiring a 0.437-inch OD cross-over end spring with a 2.2 lb/in spring rate.

Installation Notes

Extension springs should be installed by qualified mechanical or HVAC technicians familiar with spring-loaded assemblies. Always de-energize or de-pressurize the associated system and relieve any existing spring tension before removing or installing the spring. Use appropriate hand tools and eye protection, as compressed or tensioned springs can release stored energy suddenly. Do not exceed the rated maximum work load of 8.02 lb during installation or operation.
