Description
Square tube insert 25×25 mm, white

The white square tube insert for 25×25 mm profiles is a practical finishing component that closes the open end of a tube or hollow section. Inserts of this type give the profile edge a neat, uniform finish and are commonly used in frame structures.
The insert consists of a flat head that covers the edge of the profile and a ribbed stem that is pushed inside. The ribs on the stem press against the profile wall and hold the insert in place. The wall thickness range given in the specification allows it to fit different versions of 25×25 mm profiles.
Material and construction
Made from polyethylene, it is suitable for finishing structures made from steel and aluminium profiles, such as frames, railings and support structures. The white colour complements light-coloured structures and painted profiles.
Selection
When selecting an insert, check the external dimension of the profile and its wall thickness, and compare them with the specification below. A correctly sized insert fits snugly inside the profile, with the head sitting against its edge.

Applications
- closing the ends of 25×25 mm square profiles in steel and aluminium structures
- finishing frames, supporting frames and railings
- covering the open end of a hollow section
