Description

Round tube insert 1/2" (Ø 21.3 mm), black

Round tube insert 1/2" (Ø 21.3 mm) in black is a finishing component that closes the open end of a tube. The push-fit inner part with fins fits into the profile, and the flat outer flange neatly conceals the cut edge of the tube.

Inserts of this type are used to close the ends of steel and aluminium tubes in support structures, frames, balustrades, racks and metal furniture. A closed tube end looks neat, and the insert itself is a simple, quick-to-use finishing solution.

Matching to the profile

  • Designed for round tubes with an outer diameter of 21.3 mm (1/2")
  • Intended for tubes with a wall thickness within the range given in the specification
  • The fins on the inner part hold the insert in the tube opening
  • Sold individually – convenient for ordering the exact number of components needed for a job

Before installation, make sure the end of the tube is free of burrs. Push the insert into the open end of the profile until the flange rests against its edge. When choosing an insert, the key factors are the outer diameter of the tube and its wall thickness.

Round inserts with fins are commonly chosen where the open end of a tube needs to be closed neatly and durably. The black colour works well with profiles that are painted or lacquered in dark shades. Full dimensional data is provided in the specification tables below.
