Description
Rectangular tube insert 50×100 mm, grey, wall thickness 2.0–4.0 mm

The grey Rectangular tube insert 50×100 mm is a simple finishing component that closes the open end of a hollow section. It is designed for tubes with wall thicknesses within the range given in the specification, allowing it to be used with several tube variants of the same nominal size.
The body is made of polyethylene. Once pressed in, the flat flange covers the edge of the tube and gives the end a neat, closed appearance. The ribbed shank with fins sits inside the tube, and the insert is secured by pressing it in, without additional fasteners.
Applications
- protecting the open ends of rectangular hollow sections against dirt and the ingress of contaminants
- finishing support structures, frames and stands made from rectangular tubes
- neatly closing tube ends visible in the finished structure
- neutral grey colour that is easy to match to most structures
Inserts of this type are used with steel, aluminium and other hollow sections. Before purchasing, measure the internal dimensions of the tube and its wall thickness and compare them with the specification, as these dimensions determine whether the insert will fit correctly.

When selecting an insert for a particular tube, the heights of the flange and shank and the dimensions of the core and fins are important. These determine how the component sits in the tube, allowing the installer to quickly check whether the insert fits the section.
