RS PRO Stainless Steel Extension Spring, 27.2 x 4 mm
Looking for a solution to keep different objects together or securely closed when they are pulled apart? This stainless steel extension spring from the RS PRO range absorbs and stores the energy of pulling forces between components.
Two looped hooks on each end of the item allow you to easily attach and connect your objects without having to go through any additional effort to bend or shape the spring. The stainless steel construction makes this product robust and resistant to corrosives so you can confidently use it in harsh indoor and outdoor settings without it rusting or breaking.
This item carries the RoHS (Restriction of Hazardous Substances) certification, meaning it contains only trace amounts of any materials that can harm your health. You can use the spring on garage doors, agricultural machinery and trampolines.
