Square Inserts & Glides
Square tube inserts are pushed into the ends of hollow tubes that are used to create furniture, shelves and racks. Our inserts protect the ends of the tubes, covering sharp edges and, depending on the style, act as either an end cap or a load bearing foot. We offer several styles of square tube inserts including low profile, rounded, felt based, steel based, angled and domed.

We also offer square threaded inserts that are designed to accommodate adjustable feet and leveling mounts, including heavy duty inserts suitable for machinery. Ribbed to fit multiple gauges, the HDPE material and zinc-plated steel threaded insert makes them a strong, durable and reliable product.
