Product Information

Square Threaded Inserts from Sinclair & Rush.

Our Square Threaded Inserts offer a simple way to add height adjustable feet or castors to tubular furniture and frames. They fit flush to the outside dimensions of the tube, are easy to fit and can then not be removed without the use of tools. Made from durable LDPE, this injection moulded item can be manufactured in a large variety of colours. We stock a standard range and run bespoke versions at our factory in Kent.

Match the outside dimensions of your tube to the outside dimensions of the Tube Insert, then allow for the correct wall thickness option (the thickness of the metal wall). We stock Threaded Adjustable Feet to use with our Threaded Inserts.

Product Uses

Tube Inserts are used as a low-cost alternative to welding or finishing open tubes. With multiple colour and finish options, as well as the ability to customise with embossed logo's or printed instructions, Tube Inserts are a way of adding a high-quality feel to your product. Once fitted, any sharp ends are protected and the tube is closed off from dirt and debris. When fitted to the tubes used as furniture or frames, the Threaded Tube Inserts allow for the simple fitting of Adjustable Levelling Feet.
