Description
Square tube insert 80×80 mm, anthracite, wall thickness 5.0–8.0 mm

The Square tube insert is a practical finishing component for businesses that protect the open ends of steel and aluminium tubes. The anthracite (RAL 7016) version gives tube ends a dark, uniform finish.
The ribbed internal section slides into the tube, while the flat external flange covers the tube edge and gives the end a neat appearance. Inserts of this type are used to close the openings of hollow tubes, protecting their interiors from dirt and covering sharp cut edges.
The dark anthracite colour complements dark-coloured structures. Before ordering, check the wall thickness of the tube, as this determines how well the ribs fit. The supported thickness range is given in the specifications.
- Protects the open ends of square tubes
- Neat finish for structures in anthracite (RAL 7016)
- Ribbed internal section for insertion into the tube
- Covers the cut edge and protects the inside of the tube

The insert dimensions, including the heights of the external and internal sections and the dimensions of the core and ribs, are given in the specifications below to help you check the fit before installation.
