Description
Square tube insert 16×16 mm, grey
Square tube insert 16×16 mm in grey, made of polyethylene. It provides a neat finish to the open end of a hollow profile and is sold individually.

The insert consists of a flat flange that covers the edge of the profile and a ribbed section that is pressed into the profile. The ribs hold the insert in place inside the profile opening.
Applications and selection
- Closing the ends of square profiles with a nominal size of 16×16 mm in steel and aluminium structures
- Finishing frames, supports, bases and equipment components made from square tubes
- Providing a neat finish to open profile ends visible in the finished structure
- Easy selection: choose the insert according to the nominal profile size and wall thickness
Material and construction Polyethylene is a lightweight, moisture-resistant material commonly used to manufacture profile inserts. The neutral grey colour complements steel and aluminium components, while the smooth flange gives the profile end a neat appearance.
Installation Press the insert into the open end of the profile until the flange rests against its edge. Before installation, check that the profile dimensions match those in the specifications and that the profile end is clean and free of burrs.
For installation companies Inserts of this type are commonly used to finish structures made from hollow profiles, such as supports, stands and auxiliary frames. Individual sales allow you to purchase exactly the number of inserts needed for each project.
