Description
Square tube insert 140×140 mm, grey

The grey 140x140 mm Square tube insert is a finishing component for closing the ends of square hollow-section tubes. It is made of polyethylene, and its flat head neatly conceals the open end of the tube.
The inner section of the insert has ribs that slide into the tube opening. The insert is pushed into place without additional fasteners, while the flat head sits against the end of the tube and closes the opening.
The insert is designed for square tubes with a nominal size of 140 x 140 mm. The tube wall thickness range given in the specification allows it to be used with different tube variants of this size. Plastic inserts are commonly used to finish tube ends in steel structures, fences, shelters, frames and supports.
Polyethylene is a material commonly used to manufacture inserts for hollow-section tubes. When selecting an insert, compare the nominal size and wall thickness of the tube with the specification. The product is sold individually.
