Gardner Spring V6C Extension Spring 16.71 Lb 0.5 in Od

Product Description

The GARDNER SPRING V6C is a galvanized steel extension spring rated for a maximum work load of 16.71 pounds and a spring rate of 4.75 lb/in. With a 0.5-inch outside diameter and a wire diameter of 0.0625 inches, this spring is built for reliable tension-load applications across a wide range of mechanical and industrial systems. The zinc-plated galvanized finish provides corrosion resistance in demanding environments. At a free length of 4 inches and a maximum extended length of 6.15 inches, it delivers consistent, predictable extension performance. Typically installed by maintenance technicians, machine builders, and mechanical contractors.

The V6C extension spring is suited for residential and light commercial mechanical assemblies where a compact, moderate-load extension spring is required. Typical applications include door hardware, HVAC damper linkages, panel latches, and general tensioning mechanisms. An initial tension of 2.9 pounds means the spring resists opening until that threshold load is exceeded, which is useful in applications requiring a positive return force. This spring is sold in packages of 3 pieces, making it practical for service kits and small-batch installations.

Key Features

• Maximum work load of 16.71 pounds supports moderate-tension mechanical applications
• Spring rate of 4.75 lb/in provides consistent, linear extension force
• Initial tension of 2.9 pounds delivers positive return force without pre-loading
• Galvanized zinc-plated steel finish resists corrosion in exposed or damp environments
• Compact 0.5-inch OD fits tight mechanical clearances
• Sold in a 3-piece package for service and replacement use

Compatibility

Designed as an OEM-style replacement or service extension spring for mechanical assemblies requiring a 0.5-inch OD, 4-inch free-length steel extension spring with a 4.75 lb/in spring rate.

Installation Notes

Extension springs should be installed by qualified mechanical or maintenance technicians familiar with spring-loaded assemblies. Always relieve system tension and de-energize any connected actuators or motors before removing or installing springs. Use appropriate spring hooks or pliers rated for the load to avoid sudden release. Inspect mounting hooks and attachment points for wear before installing a replacement spring.
