Description
Rectangular tube insert 40×120 mm, black, wall thickness 1.7–3.0 mm

The black Rectangular tube insert 40×120 mm is a finishing component for closing the open ends of hollow sections. It is designed for tubes with a wall thickness of 1.7–3.0 mm, so one model fits the entire thickness range.
The internal section of the insert has ribs that press against the tube wall and hold it in the opening. The flat external flange covers the cut edge of the tube and gives the end a neat, uniform appearance. The insert is made of black polyethylene.
Applications and selection
- Closing the ends of rectangular tubes with nominal dimensions of 40×120 mm
- Covering the sharp cut edge and finishing tube ends visible in the completed structure
- Closing tube openings in support structures, frames and equipment components
- Available individually — one piece per tube end

When selecting an insert, compare the tube's external dimensions and wall thickness with the dimensions of the internal section. A wall thickness within the specified range allows the ribs to seat correctly and hold the insert securely in the tube. Plastic inserts are commonly used to protect the ends of hollow sections in various types of structures.
