Description
Rectangular tube insert 30×80 mm, anthracite

The Rectangular tube insert 30×80 mm in anthracite (RAL 7016) is a practical finishing component for closing the open ends of hollow sections. It is made of polyethylene, and the push-fit internal section with ribs sits inside the tube and holds the insert in place.
Applications and selection
- Closing the open ends of rectangular tubes
- Providing an attractive finish to steel structures, frames and supports in a dark, neutral colour
- Protecting the inside of the tube against the ingress of dirt
- Providing a uniform, neat appearance at visible tube ends in the finished structure
Inserts of this type are used where the open end of a tube would be visible or exposed to dirt. The outer flange covers the edge of the tube, giving the closed end a neat appearance. To select the correct insert, match the nominal dimensions and wall thickness of the tube to the specification below.
Installation
Push the insert into the tube opening until the flange rests against its edge. The ribs on the internal section grip the tube walls and hold the insert in place. Polyethylene is a material commonly used for this type of cover.

The insert consists of a flat outer flange and a hollow internal section with ribs that grip the tube walls. This design allows the tube end to be closed quickly without additional fasteners or tools.
