If you need to keep heavy items attached while allowing them limited movement away from each other, choose this steel extension spring from RS PRO. It links items together and absorbs the forces when you pull them apart. When the pulling force is released, the objects return to their original position.


This sturdy spring is made from carbon-steel piano wire, so it has the high tensile strength necessary to handle heavy-duty applications. It has a closed loop at both ends, making it easy to install. Simply attach a hook or carabiner clip for a quick and secure connection.

The spring complies with the Restriction of Hazardous Substances (RoHS) standards, meaning it contains only minimal amounts of any potentially harmful materials. Springs like this are ideal for trampolines, garage doors and commercial machinery.
