What size conduit would *likely* fit this?

Ordered some metal sockets for the garage from TLC;

Is there a single "standard" size of conduit that is typically used with these? 20mm or 25mm?

If the answer is "it could be either", that's fine and I'll wait till they pitch up, measure them then order the conduit...

The knockouts are 20mm. You can drill them out to 25mm if you have many cables to run to them.

Perfect - cheers, mate. Off to the TLC website for me
