Description
Round tube insert 1 1/4" (Ø 42.4 mm), grey
The grey Round tube insert 1 1/4" (Ø 42.4 mm) is a push-fit finishing component that closes the open end of a tube, giving the structure a neat, finished appearance. It is suitable for finishing frames, railings, support structures and supports made from round tubes with imperial diameters.

The insert consists of a flat head that covers the tube edge once installed, and an inner section with ribs. The ribs press against the inner wall of the tube and hold the insert in place, while the head covers the cut edge.
Applications and selection
- Closing the ends of round tubes with an outside diameter of 42.4 mm (1 1/4")
- Finishing frames, railings, support structures and supports made from round tubes
- Providing a neat finish to a tube end after cutting to size
- The wide range of compatible tube wall thicknesses allows the same insert to be used with different tubes of the same diameter
When selecting an insert, the tube's outside diameter and wall thickness are essential, as they determine how firmly the ribs press against the inside of the tube. Push the insert into the open end of the tube until the head sits flush against the end. The neutral grey colour blends well with typical tubular structures.
Ribbed inserts are a common solution for tubular installations and structures. Push-fit installation requires no additional fasteners, and each piece is sold individually, making it easy to order the quantity needed for the number of tube ends in a project.

Insert dimension labels: C is the height of the outer section (head), H is the height of the inner section pushed into the tube, R is the tube wall thickness, and d1 and d2 are the core and rib dimensions respectively. All these dimensions are specified below.
