Round tube insert, domed, 1 1/2", black

The black domed Round tube insert, 1 1/2" is a finishing component for closing the ends of tubes with a nominal dimension of 48.3 mm. The rounded, domed head covers the open end of the profile, providing a neat, attractive finish where tube ends remain visible.

The internal part of the insert is shaped as a ribbed shank with fins. When pressed into the end of the tube, the fins grip the profile wall and hold the insert in place. The design accommodates tubes with different wall thicknesses within the same external diameter, making it easier to select an insert for different profiles.

Applications

Inserts of this type are installed by pressing them into the end of the tube, without additional fasteners. The black colour complements dark profiles and structural components, while the plastic used to make such inserts is commonly used where low weight and easy installation are important.

Design and selection

The insert consists of two parts: an external domed head that remains visible after installation, and an internal part that fits inside the tube. Selection depends on the tube's external diameter and wall thickness, so it is advisable to check both dimensions of the profile to be closed before ordering. Detailed dimensions of the individual parts are given in the table below.
