Description
Rectangular tube insert 30×50 mm, grey

The grey Rectangular tube insert 30x50 mm is used to close the open ends of rectangular tubes. It is made of polyethylene, a plastic commonly used for finishing components in structures, frames and supports.
The internal section of the insert has ribs that press against the tube walls and hold it in the opening. The external flange covers the edge of the tube and closes its end. The insert is designed for tubes with a nominal size of 30 x 50 mm; the compatible wall thickness range is given in the dimensions table below.
Applications and selection
- Closing the ends of rectangular tubes in frames, supports and structural bases
- Covering the open end of a tube
- Selection according to the nominal tube size and wall thickness
- Finishing steel and aluminium tubes in a uniform grey colour

Installation
Press the insert into the open end of the tube until the flange rests against the edge. The ribs enter the tube and grip its internal walls. Before installation, check that the nominal size and wall thickness of the tube match the values given in the specification, as these determine how securely the insert fits.
