Description
Square tube insert 25×25 mm, anthracite

The Square tube insert 25×25 mm in anthracite (RAL 7016) closes the open end of a tube or hollow section. It provides a neat finish to the structure and protects the inside of the profile from dirt and debris.
The internal section of the insert has fins that press against the profile walls and hold it in place. The flat external flange covers the edge of the profile for an even, clean finish. The wall thickness range stated in the specification allows the same model to be used in profiles with different wall thicknesses.
Applications
- Closing the ends of square profiles in support structures, frames and frameworks
- Finishing visible profile ends in anthracite (RAL 7016)
- Protecting open sections from dirt and debris
The insert is made of polyethylene, a material commonly used for push-in profile inserts that retains the flexibility needed for the fins to grip inside the profile.

Selecting the right profile
When selecting an insert, the nominal profile size and wall thickness are important. The external flange remains outside the profile, while the finned section fits inside it. Before ordering, compare the internal dimensions of the profile with the insert specifications.
