Washer, do you mean something like a reducer?

No, I meant similar to like a penny washer but with a hole in middle that a bush could go through. This would then pull down onto the box when the bush is tightened.

Are you allowed to add a clamp to the conduit with an earth cable attached to it?

Don’t know but it doesn’t sound the best way off doing it.

There’s a type of conduit system (Conlock) that uses push on boxes and couplers with a grub screw to use to tighten.
Apparaently it exceeds the current standard for earth continuity?
They do an adapter (looks like a coupler) which is push fit with grub screw one side and threaded the other side for brass bushes.
They’re using it at THFC.

Got a link?

Below is picture of one of the boxes that is metal that I came across after first post. As you can see, a 19mm bush probably won’t pull conduit tight to the box.

Get a bit of metal and make your own washer.

Can anyone link me up to where I can buy these old bushes? Just so I can show my wholesaler exactly what I need. Have had 3 ordered & none were what I’m after!

do you need 20mm -3/4 adaptors?

do you need 20mm -3/4 adaptors?

Mmm, possibly. That mean I would just have to take couple of & thread this onto the conduit?
