Description
Rectangular tube insert 25×50 mm, black

The black Rectangular tube insert 25×50 mm is a finishing component for closing the open ends of rectangular tubes. Inserts of this type cover the tube opening and give the end a neat appearance.
The product is made of polyethylene. The external flange covers the edge of the tube, while the ribbed internal section is pressed into the opening. Ribbed inserts are usually fitted by pressing them into the end of the tube, without the need for additional fasteners.
Applications and selection
- Closing the ends of rectangular tubes with nominal dimensions of 25 x 50 mm
- Finishing tube ends in structures, frames and support frames
- Selection based on nominal tube dimensions and wall thickness
- Black version for use with dark-coloured components

When selecting an insert, two tube dimensions are key: the external cross-section and the wall thickness. This model is designed for tubes with a wall thickness of 1.5 to 3.0 mm. The internal section height and rib dimensions are given in the specification alongside the dimensional drawing.
The product is sold individually, allowing you to order the exact number of inserts needed for a particular job. The low weight of each item means it qualifies for small parcel delivery.
