Ø20mm 'ECO' Ribbed Dome Insert, 1-2mm

These 20mm round ECO ribbed dome inserts are designed to provide a clean, protective finish for round tube and pipe applications with a 1–2mm wall thickness. Manufactured from durable LDPE plastic, they are commonly used as tube end caps, protective feet, and decorative finishing inserts across furniture, fabrication, and light industrial applications.

If it's more of an angled foot you're after, then we have full domed and angled options or we also have a range of Tiltserts which may work better for you.

Featuring a domed profile, these inserts help improve product appearance while also protecting tube ends, flooring, and surrounding surfaces from damage. The ribbed shank design ensures a secure push-fit inside round tubing, while the flush-fitting head creates a neat professional finish.

Sizing Information
