Description
Round tube insert Ø 38 mm, anthracite

The Round tube insert Ø 38 mm in anthracite (RAL 7016) is a finishing component for closing the open ends of tubes. Once pressed into the tube, it covers the opening and closes off the interior.
Applications and selection
- Closing the ends of round tubes with a nominal diameter of 38 mm
- Finishing round tube structures such as frames, supports and handrails
- Use in tubes with a wall thickness within the range stated in the specification
- Anthracite colour (RAL 7016) for dark-toned structures
The internal section of the insert has ribs that press against the tube walls when inserted, holding the component in place. The insert is pushed into the end of the tube until the external flange rests against the tube edge.
Round tube inserts are usually fitted as the final stage of assembling tubular structures. The nominal tube diameter and wall thickness are important when selecting an insert, as they determine whether the ribs fit correctly inside the tube.
The product is sold individually, allowing you to order exactly the number of inserts required for your project.

The insert consists of an external flange that remains outside the tube and an internal section with a core and ribs that fit inside the tube. This design is typical of push-in inserts for round tubes.
