These 35x35mm square ribbed tube inserts, from the 'ECO' range, are designed to provide a clean, secure finish for square tubing with a 1–3mm wall thickness.

Tube inserts are sized using the external tube dimensions and wall thickness/gauge size to help ensure a secure fit. If you’re matching an existing insert or are unsure which size you require, the head size is usually the most important measurement to check. For added peace of mind, you can also take advantage of our free sample service to test the fit before placing a larger order.
