RS PRO Steel Extension Spring, 34.4mm x 12mm

If you need to keep two different items together but still allow them to be pulled apart a limited distance, choose this steel extension spring from RS PRO. Its coiled construction absorbs and holds energy, allowing objects to spring back together once the pulling force is released.


The spring features two closed loops that are easy to attach with carabiner clips or simple hooks. This allows you to make a quick but secure connection. The spring itself is made from carbon-steel piano wire, so it can hold a lot of weight and endure high tensile force. This makes it suitable for heavy-duty applications.


This type of extension spring is common on trampolines and garage doors and is also suitable for commercial and industrial machinery. It complies with the Restriction of Hazardous Substances (RoHS) requirements, so it contains no more than trace amounts of any potentially harmful materials.
