Description
Rectangular tube insert 80×100 mm, black, 3.0–4.0 mm wall thickness

The black Rectangular tube insert 80×100 mm provides a neat and durable closure for the open ends of hollow sections. It is suitable for finishing steel structures, frames, supports and frameworks, as well as any application where the exposed end of a section requires protection.
The insert is made of polyethylene, a material commonly used for finishing products of this type. The external flange covers and conceals the edge of the section, while the ribs on the internal section press against its walls, allowing the insert to be push-fitted into the end.
Applications
- Closing the ends of rectangular sections in steel structures, frames and frameworks
- Finishing supports and load-bearing components where the section remains visible
- Protecting the open end of a section from dirt entering
- Neatly concealing the cut edge of a section

Choosing the right insert
When ordering an insert, match it to the nominal dimensions and wall thickness of the section, as both determine whether the ribs fit correctly. An insert that is too loose in the opening will not be held securely, while one that is too tight will be difficult to push in. The exact dimensions are listed in the specification below.
