This RS PRO steel extension spring can attach two objects or components while allowing them a limited range of movement away from each other. It absorbs and stores the pulling forces between items so they will come back together once the force is released.


Installing this spring is easy thanks to the two looped hooks at either end. The spring itself is made from high-tensile carbon-steel piano wire, so it's extremely strong and able to support heavy loads.


As part of our RS PRO range, this product has been tested by engineers to ensure quality and durability. You'll often find springs like this used on trampolines and garage doors.
