RS PRO Stainless Steel Extension Spring, 38.5mm x 7.5mm, Пружина растяжения

RS PRO Stainless Steel Extension Spring, 38.5 x 7.5 mm

If you're looking for a way to keep heavy objects together while still allowing them to be pulled apart for a limited distance, use this stainless steel extension spring from RS PRO. It has a tight coil that absorbs and stores potential energy, so the items snap back together once you release the pulling forces.


Installing this spring is easy, as you can simply attach objects to the closed loops using a carabiner clip or a hook. The stainless steel provides high strength and corrosion resistance, making this a durable product that's suitable for heavy-duty applications.


As part of our trusted RS PRO range, this product has been tested for consistency and reliability. Springs like this are useful in vise grips, automotive and garage doors and agricultural machinery.
