Square Angled Tube Inserts
Square Angled Tube Inserts are designed to provide a secure, durable, and professional finish to square tubes, pipes, and box sections. Manufactured from high-quality LDPE plastic (Low-Density Polyethylene), these inserts offer a reliable push-fit solution for sealing open tube ends while also serving as replacement chair feet for furniture with angled legs.
The unique angled base allows furniture legs to make full contact with the ground, increasing stability and weight distribution. This makes them particularly useful for school chairs, office seating, workbenches, and industrial furniture. Additionally, by sealing the tube ends, these inserts prevent moisture, dust, and debris ingress, reducing the risk of internal corrosion and prolonging the lifespan of your equipment.
Choosing the Right Size
To ensure a perfect fit, selecting the correct size of Square Angled Tube Inserts is essential. Follow these steps:
- Measure the outside diameter of your square tube.
- Determine the wall thickness of your tube.
- Subtract the wall thickness from the outside diameter to find the correct ‘To Fit Tube' size.
Our inserts are available in sizes from 12mm to 23mm, covering a wide range of applications. If you are unsure which size to choose, our expert team is available to assist. Business customers can also request a free sample to test the fit before placing a bulk order.
