Description
Round tube insert 3" (Ø 88.9 mm), black

The black Round tube insert 3" (Ø 88.9 mm) is a finishing component for closing the open ends of round tubes. It is suitable for tubular structures where tube ends need to be protected and neatly finished.
Push-fit design — the internal part of the insert has ribs that press against the tube wall, while the external flange covers the edge of the tube. The insert is pushed into the open end of the tube without additional fasteners. Inserts of this type are used to close tube ends and finish cut edges.
Selecting the right tube — the insert is designed for tubes with a diameter of 3" (88.9 mm). The tube's outside diameter and wall thickness are key to selection, as they determine how the ribs fit inside the tube; exact values are listed in the tables below. The black finish complements dark profiles and structures.
- Closes the open end of a 3" round tube
- Provides a neat finish for tubular structures, such as balustrades, fences and frames
- Covers the cut edge of the tube
- Push-fit installation

Plastic construction — push-fit inserts of this type are usually made from plastic, which is lightweight and moisture-resistant. This means the component adds little weight to the structure and requires no additional processing before installation.
