Description
Rectangular tube insert 15×40 mm, grey

The Rectangular tube insert 15×40 mm is a practical finishing component for closing the open ends of hollow sections. The insert fits inside the section, limiting the entry of dirt and giving the edge a neat, even finish.
The internal section of the insert has ribs that fit inside the section and press against its walls. The external flange covers the edge of the section and conceals the cut surface. The insert is designed for sections with a range of wall thicknesses, as specified in the product specifications.
Applications
- Closing the ends of 15×40 mm rectangular sections
- Finishing support structures, frames and frameworks made from hollow sections
- Protecting the open end from dirt
- Neatly concealing cut surfaces on visible section edges
Material and construction
The insert is made from polyethylene, a lightweight, moisture-resistant plastic commonly used for this type of product. Its neutral colour suits a wide range of metal structures and remains unobtrusive on the finished product.

Before ordering, measure the external dimensions and wall thickness of the section and compare them with the values in the product specifications. Matching the insert to the internal dimensions of the section ensures that the ribs are securely seated and the flange sits evenly against the edge.
