These 50x50mm 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. Manufactured from durable LDPE plastic, they are commonly used as protective end caps, tube feet, and finishing plugs across furniture, fabrication, and light industrial applications.

The flexible ribbed shank allows the insert to achieve a firm push-fit inside square tube sections, while the flush-fit head creates a neat, finished appearance.

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.
