RS PRO Steel Extension Spring, 82.8 x 12 mm
You can use this steel extension spring from RS PRO to keep two different items together while allowing them to be temporarily pulled apart at times. It's made from sturdy piano wire, so it has a high tensile strength that's suitable for heavy-duty applications.
The spring's coil construction resists pulling and absorbs and holds energy. That means that when the linked objects are pulled in opposite directions, the spring holds them together and returns them to their original position once the pulling force is released.
The carbon-steel spring material is resistant to corrosion, meaning you can use this product in harsh industrial or outdoor environments. You'll find springs like this used for commercial machinery, domestic garage doors and securing the bounce mat to the steel frame of a trampoline.
