Description
Rectangular tube insert 15×25 mm, black

The black Rectangular tube insert 15×25 mm is a finishing component that closes the open end of a hollow tube. Made of polyethylene, it consists of a flat external flange and a ribbed internal section that fits inside the tube.
Inserts of this type are used to close the ends of steel and aluminium tubes in load-bearing structures, frames, supports and equipment. The flange covers the cut edge of the tube, providing a neat and uniform finish.
Applications and selection
- Closing open ends of rectangular tubes in structures and frames
- Covering the sharp edge left after cutting the tube
- Finishing frames, bases and equipment made from hollow tubes
- Selection according to the nominal tube size and wall thickness

The insert size is defined by the dimensions of its external and internal sections, as well as its core and ribs. When selecting an insert, check the nominal tube size and wall thickness, as these determine whether it will fit correctly.
The ribs on the internal section hold the insert in the tube, while the flange, with the height specified in the specifications, provides a neat finish. Polyethylene is a material commonly used for finishing products of this kind. The black colour gives the end a cohesive, understated appearance.
