Gardner Spring 36-49-2250 Extension Spring 0.36in Od

Product Description

The GARDNER SPRING 36-49-2250 is a small-diameter extension spring designed for light-load tensioning and return applications across HVAC, electrical, and mechanical assemblies. It measures 0.36 inches in outside diameter with a 0.049 inch wire diameter and a maximum extended length of 1.2 inches. The spring rate is 8.3 pounds per inch, with an initial tension of 1.2 pounds, making it suited for applications requiring consistent, predictable pull force in a compact form factor. Installation is typically performed by HVAC technicians, electricians, or mechanical service technicians during equipment assembly or component replacement.

This extension spring fits compact mechanical linkages and control assemblies commonly found in residential and light commercial HVAC equipment, electrical panels, and related trade equipment. The 2-1/4 inch inside hook length accommodates standard hook-mount configurations. Its small wire diameter and tight coil geometry make it a direct replacement option for original equipment spring components in similar load-range applications. Package quantity is 3 springs per pack with a minimum order quantity of 1 pack.

Installation Notes

Extension springs should be installed with both hooks fully seated before tensioning the assembly. Power down or de-energize any equipment before servicing spring-loaded mechanisms. Use appropriate hook or needle-nose pliers to seat the spring without overstretching the coils beyond the maximum extended length. Follow applicable equipment service documentation and relevant codes when replacing springs in control linkages.
