Description
Square tube insert 70×70 mm, black

The black Square tube insert 70×70 mm is a practical finishing component for businesses sealing the open ends of steel and aluminium profiles. Once fitted, it covers the profile opening, giving the structure a neat, uniform appearance and reducing the ingress of dirt.
The internal section of the insert has ribs that press against the profile walls and hold it in place. The insert is designed for profiles with a range of wall thicknesses, while the flat external flange covers and conceals the profile edge.
Applications
- sealing the ends of square profiles in load-bearing and support structures
- finishing frames, supports, railings and fences made from hollow sections
- protecting profile edges against dirt and moisture ingress
- providing a neat finish to visible structural components
The insert is made of polyethylene, a material commonly used for finishing components because it is resistant to moisture and does not corrode. The black colour complements structures in dark shades.

Selection and installation
When selecting an insert, check the external dimensions of the profile and its wall thickness. Push the insert into the open end of the profile until the external flange rests against the edge and the ribs grip the internal walls.
