Our extensive range of high quality plastic tube inserts are designed to give a finished appearance to any furniture item or product which incorporates plastic and steel tubing. Tube inserts look smart as well as allowing items of furniture to be moved more smoothly across a surface without a dragging effect. High quality inserts will also help to minimise indentation marks in flooring, with weight distributed more evenly.

At Cotel we manufacture tube inserts in a wide range of shapes and sizes, and can offer customisation for high quantity orders. The majority of our inserts are made from various types of polyethylene. Download our catalogue to see our full range.

Square tube inserts

Standard square tube inserts and end caps range in size from 10mm to 150mm. We manufacture flat, domed and angled inserts in plastic and rubber.

Round tube inserts

Round tube inserts are available in a wide variety of diameters. We offer round inserts in lightweight or heavy duty options. A choice of colours is available as standard on some of our round inserts.

Rectangular tube inserts

Rectangular inserts and box section endcaps are available in a variety of styles, including domed, angled and a curved base. Whether you need rectangular, round or square inserts, you can choose from ribbed or plain shanks. Ribbed shanks combine ease of fitting with a neat finish. We supply threaded inserts for furniture requiring castors, and we offer a choice of plastic or metal threading.

Metal inserts

In addition to our plastic inserts, we offer a comprehensive range of metal tube inserts, in a variety of materials including aluminium alloy and steel tube inserts. Chrome capped ribbed products combine the smart look of a metal finish with the optimum fitting of a ribbed shank.
