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

The grey 1/2" Round tube insert provides a neat finish for the ends of round tubes with an external diameter of 21.3 mm. Inserts of this type are used to finish tubular structures where the open end of the tube needs to be covered.
The insert has an external flange that covers the edge of the tube when pressed in, and an internal section with ribs that fit inside the tube opening. It is designed for tubes with a wall thickness within the range given in the specification, and its dimensions, as shown in the technical drawing, make it easier to select the right insert for a particular tube.
The grey colour allows the insert to blend in with light-coloured and neutral structural elements. The product is sold individually.

Applications and selection
- closing the ends of 1/2" (21.3 mm) diameter round tubes
- finishing the ends of frames, supports and other structures made from round tubes
- covering the open end of a tube
- selection according to tube diameter and wall thickness
Plastic tube inserts are usually installed by pressing them into the end of the tube, so check the tube's external diameter and wall thickness before purchasing.
