Standoffs are a barrel that has internal threads. They can either be threaded the entire length or from each end depending on the part’s overall length. This allows you to use a fastener to mount the standoff on one end and a puck to mount your panel on the other end. You can then hang or change panels without having to take the whole assembly down.
Our Standoffs are made of stainless steel. Unlike cheap imitations, they will not corrode or oxidize.
