Description
Square tube insert 50×50 mm, grey (RAL 7024), wall thickness 3.5–5.0 mm

The grey (RAL 7024) Square tube insert 50×50 mm closes the ends of hollow sections and gives them a neat, uniform finish. It is a practical component for installers and contractors who need to quickly protect open tube ends.
The insert is pressed into the open end of the tube. It is made of polyethylene. Ribs on the internal section press against the tube walls and hold the insert in place, while the flat flange covers the tube edge on the outside.
Inserts of this type are used at the ends of support structures, fences, railings, frames and furniture made from square tubes. The closed tube is protected against the ingress of dirt, while sharp cut edges are concealed beneath the flange.
Polyethylene is a material commonly used for inserts and protective caps. The neutral grey RAL 7024 colour complements steel and aluminium sections in anthracite and grey shades.

Typical applications
- Finishing the ends of square tube posts and uprights
- Finishing frames, supports and structural bases
- Railings and fence components
- Metal furniture and shelving made from hollow sections
