This is one of those "does it exist & if so, what's it called?" posts.

I want to stick a cupboard up on a hollow wall (plasterboard on one
side of the studs, lath & plaster on the other, I think), make a hole
through the wall, & pass some power leads (with plugs) and network
cables through it. Ideally, I'd like to cut a circular or square
hole, something like 75 to 100 cm wide, on both sides of the wall and
stick a two-part thing in it to neaten it. I imagine something ought
to exist that comes in two halves that overlap/nest in the middle for
this purpose.

Does it exist & if so, what's it called?
;-)

Thanks,
Adam

2 x 80mm diameter desk tidy /cable access ports glued in place might do it. If the wall is very thick a short length of plastic pipe to bridge the gap might be necessary

That's a very big hole. I hope you meant mm.

If you make a suitable hole right through the wall you don't need a tube in
two halves; just use one piece cut to the right length. A short piece of
plastic drainpipe would work. Or the duct meant for use when people put
extractor fans through walls.

When I needed to do that, I used a bit of kitchen extractor ducting
through the wall, with a couple of wall plates from the same range to
finish the ends.

If you did not want to push the plugs through, could you not make do
with a much smaller hole? Use an extension lead, and plug into that?

Good gravy, yes.

Hmm, extractor fan parts might be good.

I did exactly this with a bit of 40mm wastepipe, same sized holesaw and
a tube of caulk. Takes IEC/kettle connectors quite happily. If the ends
had been visible I'd have stuck a brush plate over each (

Where are we going and why am I in this handbasket?

Yes but its the way the plaster splits and crumbes at the edges. There used
to be a gadget that shop fitters and those office partition builders used to
use like this, but like others, I have no idea what it was called, but as
most interior walls of this sort were very thin, I'd imagine itt would be
too short.

Would it not be much neater to fit a socket in the wall?

On further consideration, I think I'm only going to put one thing (the
WAP) there, so I just need a small hole to pass a network cable and
the small DC plug coming from the wall wart through the wall. I might
use one of those "brush" faceplates, probably with a back box, a short
piece of flexible conduit, & some kind of caulk around the conduit on
the other side (which will be inside a wardrobe).
