Description
Rectangular tube insert 15×50 mm, black

The black Rectangular tube insert 15x50 mm is a practical finishing component that closes the open end of a hollow tube. Its neat external flange covers the cut edge, giving the structure a tidy, uniform appearance.
The insert is made of polyethylene. The ribbed internal section is pushed into the tube and held in place by friction. Inserts of this type are commonly used in steel and aluminium structures, frames, racks and support components where the open end of a tube needs finishing.
Applications
- Closing the ends of rectangular tubes in support structures and racks
- Neatly finishing visible tube ends in frames and bases
- Providing a uniform black finish to structural components
- Covering cut tube edges

Selecting the correct tube size
Select the insert according to the nominal tube dimensions and wall thickness. Before purchasing, measure the tube's external dimensions and wall thickness to ensure the ribs enter the tube with consistent, firm resistance. The dimensions of the internal section, core and ribs are given in the specifications below.
Installation
Push the insert into the open end of the tube until the flange rests against the end face. Before insertion, the tube end should be clean and free of cutting burrs to make it easier to seat the ribs. The product is sold individually, making it easy to match the number of inserts to the number of tube ends being closed in a given project.
