Description
Rectangular tube insert 20×70 mm, black
The black Rectangular tube insert 20×70 mm is a finishing component for closing the open ends of steel and aluminium tubes. Made of polyethylene, it has ribs on the inner section that press against the tube walls and hold the insert in place.
The insert is designed for tubes with a nominal size of 20 × 70 mm. Its compatible wall thickness range covers typical hollow sections used in structures. The flat flange covers the edge of the tube and gives its end a neat, finished appearance.
Applications and installation
- protecting tube ends in frames, frameworks and support structures
- finishing open ends of hollow sections in metal components
- installation by pressing the insert into the open end of the tube, without additional fasteners
- protecting the inside of the tube from dirt and covering the sharp cut edge
Plastic inserts are commonly used to close tubes because polyethylene is lightweight and easy to work with, while the ribs hold the insert in place by friction. When selecting an insert, check the nominal tube size and wall thickness, as these determine whether it fits correctly.
The insert consists of a flat outer flange and an inner section with a core and ribs. The flange rests on and covers the tube edge, while the ribs flex during insertion to accommodate different tube wall thicknesses.
