RS PRO Stainless Steel Extension Spring, 41.4 x 6 mm


This stainless steel extension spring from RS PRO will keep different objects securely closed or bound together while also allowing them to be pulled apart. The tight coil absorbs and stores potential energy, returning the items to their original position once the pulling forces stop.


This spring is made from stainless steel for high strength and durability, as well as corrosion resistance. This means you can use it in outdoor settings or harsh environments that are subject to moisture or humidity without compromising performance.


For easy installation, simply attach the objects to either of the two closed loops using a hook or clip. You'll find springs like this used in trampolines, garage doors and agricultural machinery.
