Description
Square tube insert 50×50 mm, grey, wall thickness 3.5–5.0 mm

The grey Square tube insert 50×50 mm is a finishing component that closes the open end of a hollow section. It is designed for tubes with a wall thickness of 3.5–5.0 mm, so one size accommodates several wall thicknesses.
The insert consists of an external flange that covers the edge of the tube and an internal section with fins that slides inside the tube. Inserts of this type protect tube ends from dirt and contaminants and provide a neat finish to the structure.
Made from polyethylene, a material commonly used for tube inserts, it is lightweight and resistant to moisture. The neutral grey colour provides a discreet finish that blends in with the structure.
Applications
- Finishing the ends of 50×50 mm square tubes in steel and aluminium structures
- Protecting open tube ends in frames, frameworks and supports
- Neatly closing tube ends in support structures and equipment

Selecting the right insert
Two factors are essential when selecting an insert: the external dimension of the tube and its wall thickness. An insert matched to both dimensions fits securely inside the tube, while the flange covers its edge evenly. Before ordering, measure the tube and compare it with the dimensions in the specification.
