Description
Square tube insert 70×70 mm, grey

The grey Square tube insert 70×70 mm is a finishing component for closing the open ends of hollow tubes. Made of polyethylene, it is used wherever an open tube end needs a neat and safe closure.
The insert's shank has fins that press against the inner walls of the tube, while the flat head covers its edge. One variant is suitable for tubes with different wall thicknesses, making it easy to fit to standard square tubes of this nominal size.
Applications
- Closing the ends of square tubes in steel and aluminium structures
- Finishing components of support structures, frames and bases
- Protecting the inside of the tube from dirt and its edges from damage
Polyethylene is a lightweight thermoplastic widely used for finishing products. The insert is sold individually and is lightweight, so it is shipped as a small parcel.

Choosing the right tube
The external section height indicates how far the head projects above the edge of the tube, while the internal section height indicates how deeply the insert's shank enters the tube. The core and fin dimensions describe the section fitted inside the tube. Before purchasing, measure the tube's internal dimension and wall thickness.
