Description
Rectangular tube insert 15×25 mm, anthracite
The Rectangular tube insert 15×25 mm in anthracite (RAL 7016) is a finishing component that neatly closes the open end of a hollow section. For installation companies, it is a simple way to give steel or aluminium section structures a neat, uniform appearance.

Applications and selection
- closing the ends of rectangular tubes with nominal dimensions of 15 x 25 mm
- fitting into tubes with wall thicknesses within the range specified for this insert
- finishing balustrades, fences, frames and support structures made from hollow sections
- covering sharp, unfinished edges of cut tubes
- dark anthracite colour to match dark-coloured structures
Design and installation – the insert has a flat outer flange that sits against the end of the tube and covers its edge. The inner part has ribs that provide a secure interference fit when pressed into the tube. Installation simply involves pressing the insert into the open end of the tube.
Material and construction – the insert is made of polyethylene, a plastic commonly used for this type of product because of its flexibility and resistance to moisture. The anthracite (RAL 7016) colour allows it to blend in with dark steel and aluminium structures.
Press-fit inserts are selected according to the tube's cross-section and wall thickness, so it is advisable to check both dimensions before ordering. A correctly sized insert fits securely, with its flange sitting flush against the end of the tube.
