RS PRO Square Nylon Tube Insert

Inserting the threaded tube gives you an attachment point that's easy to install – all you need to do is tap it into place. The threaded grip holds the self-levelling castors or feet firmly in place once it's in the tube.

The reinforced black nylon outer body of the tube is durable and long-lasting, while the nickel-plated brass bush offers good resistance to corrosion. This makes the tube insert a good choice for heavy-duty use under weighty, bulky machinery without the risk of buckling.
