Description
Rectangular tube insert 40×100 mm, grey, wall thickness 1.5–4.0 mm

The grey Rectangular tube insert 40×100 mm is a finishing component that closes the open end of a tube or hollow section. It is made of polyethylene and designed for profiles with a wall thickness of 1.5 to 4.0 mm.
The insert consists of a flat flange that covers the edge of the profile and a ribbed stem that is pushed inside. The ribs on the stem adapt to the profile walls and hold the insert in place once pressed in.
Applications and selection
- closing open ends of rectangular steel and aluminium profiles
- providing a neat finish to structures, fencing, supports and frames
- covering the sharp edge left after cutting a profile
- one piece per profile end
When selecting an insert, check the external dimensions and wall thickness of the profile, as the ribbed stem is designed for a specific range of wall thicknesses. Polyethylene inserts are lightweight and are installed by pressing the stem into the open end of the profile until the flange rests against its edge.

The external part height indicates how far the flange projects beyond the edge of the profile, while the internal part height indicates how deeply the stem sits inside the profile. The full dimensions of the insert are provided in the specifications below.
