RS PRO Stainless Steel Extension Spring, 37.7mm x 5.5mm

From the trusted brand RS PRO, a range of high-quality stainless-steel extension springs when extended create a resistance to a pulling force, absorb and store energy. Our extension springs are quick and easy to install, commonly used on garage door assemblies, automotive interiors and exteriors, and much more.

Extension springs are coils attached by two components from both ends of the spring. When pulled apart the extension springs pull them back together again. The springs' tension can be adapted depending on the application load requirements.

Extension springs are often the least expensive part of your assemblies, failure can mean costly machine downtime and product rejects. To ensure quality and longer reliability RS PRO offer a range of stainless steel extension springs with various spring rates and length to suit your application.

Extension springs should not be exposed to the same stress levels as a compression springs.
