This steel extension spring from RS PRO allows you to link two heavy objects together. Its coil construction absorbs and stores potential energy, so when you pull the objects apart, they return to their original position as soon as the pulling force is released.


Attaching the spring is easy, as it has one closed loop at either end. Simply link the objects to the loop using a hook or carabiner clip for a secure connection that's quick to apply.


This spring is made from high-strength piano wire, so it's suitable for heavy-duty applications and powerful pulling forces. The carbon-steel material is resistant to corrosion and won't rust if exposed to moisture or humid conditions, making this a durable, long-lasting product.
