Need an easy-to-use solution for attaching castors or feet to heavy equipment? These threaded tube inserts from our trusted RS PRO range are made to support heavy-duty adjustable feet and to fit into square-shaped tubing.


When you insert the threaded tubes, you'll get an attachment point that's simple to install. All you'll need to do is tap them into place. Once you've inserted them into the tubes, the threaded grip will firmly hold the self-levelling feet or castors in position.


The reinforced black nylon outer bodies of these tubes are durable and long-lasting, while the nickel-plated brass bushes offer excellent resistance to corrosion. This means that the tubes' inserts are suitable for use under bulky or heavy machinery and won't buckle when subjected to heavy-duty use.
