Details & FAQs
Castor Accessories
This round expanding tube adaptor lets you fit a single bolt hole castor into the open end of a round tube leg with an internal diameter of 18mm to 19.5mm. Push it into the tube, tighten the stud and the body expands to grip the inside wall firmly. The threaded stud left at the bottom then takes your bolt hole castor, giving a secure internal fixing for castors on trolleys, chairs, tables, racks and tube-framed furniture.
If you are looking for a round tube castor insert, an 18mm to 19.5mm round tube adaptor, an expanding castor fitting for small round tube legs or a simple way to add wheels to round tube furniture, this adaptor is a quick, tidy and reliable solution.

Where It Works Best

Frequently Asked Questions
How does an expanding tube adaptor work?
Push the adaptor into the open end of the tube, then tighten the stud. This pushes the body outwards so it grips the inside of the tube firmly.
What size tube does it fit?
It suits round tube with an internal diameter of 18mm to 19.5mm. Measure across the inside of the tube, not the outside, before ordering. Larger sizes are also available.
Is a castor included?
No, the castor is sold separately. The adaptor is designed to take a single bolt hole castor on its threaded stud.
Can I use it on square tube?
No, this version is shaped for round tube. For square tube legs, choose a square tube adaptor in the matching size.
Do I need to drill or weld the tube?
No. The adaptor grips inside the tube by expansion, so no drilling or welding is needed as long as the tube end is clean and open.
