I'm trying to find the manufacturer of 'heavy duty' round plastic conduit-
ideally about 20 mm in diameter.

As far as I can tell, there is no real standard for this stuff- other that
the outside diameter- and I've seen stuff with very thin walls, some
thickish, but only one really thick type. This makes the stuff quite rigid-
which is what I need for this application. It is 'pure white' like the more
common stuff and the walls must be almost 3mm thick.

I know the stuff exists (I had a bit in my hand the other day but foolishly
didn't follow it up at the time).

Applicaiton is DIY but not 'normal' electrics- the normal stuff from the DIY
sheds and even the local electrical factor isn't rigid enough.

Anyone know the product?
