These extension springs are designed to expand, elongate and resist pulling force. They can be installed easily on a mounted hook or loop. The finish will offer corrosion resistance. GL Metal offers a variety of treatment and finishing options for custom springs made from standard or special materials.
The long bending springs can be applied for copper pipes, aluminum pipes, thin-walled steel pipes, etc. You should use one bender over the tube and another bender inside the tube for a better result.
