Description
Rectangular tube insert 20×100 mm, brown, wall thickness 1.5–3.0 mm

The brown Rectangular tube insert is used to close the open ends of hollow sections. It provides a neat finish and protects the inside of the tube from dirt and moisture. Its brown colour blends visually with tubes of a similar shade.
The insert is made of polyethylene, a plastic commonly used to manufacture inserts and caps. Inserts of this type consist of a smooth external flange that covers the edge of the tube and a ribbed internal section that is pressed into the tube opening. The flange conceals the sharp cut edge, while the ribs adapt to the inside of the tube.
Applications
- Closing the ends of rectangular tubes in structures where cut edges are visible
- Protecting the inside of the tube against the ingress of dust, dirt and water
- Providing a neat finish to frames, railings, stands and similar structures made from hollow sections
- Preventing snagging on the sharp edges of an open tube

Selecting the right insert
The nominal tube size and wall thickness are key when selecting an insert, as they determine how the internal section fits inside the tube. Press the insert into the tube opening until the flange rests against its edge. The dimension labels in the drawing (C, H, R, a x b, a1 x b1) correspond to the parameters in the specification tables below and make it easier to check compatibility with the tube before ordering.
