This is probably a dumb question but I haven't found a satisfactory
solution...

I have some surface mounted equipment (e.g. heating controller,
security controller) into which I must terminate some low voltage
(50V) cables (e.g. RS485, PIR sensor connections). The equipment
enclosures have knockouts on the underside through which the cables
enter.

The cables are run within dry lining. What is a neat way to bring the
cable out through the plasterboard and up into the equipment? I could
simply drill holes in the plasterboard and thread the cable through but
this wouldn't look nice. I could have some 20mm conduit coming out of
the wall and up into the knockouts which might look a bit better. A
surface-mounted junction box (about 250mm width x 90mm height) with
rear-entry knockouts occurred to me, but I can't find a decent source.

Does anyone have some neat ideas?


Your wall mounted equipment should be fitted to a timber panel which is in
turn fixed to the surface of the plaster board wall. This is especially so
if the equipment houses mains voltage transformers or switch gear, and it
acts as an extra layer of insulator material against the paper surface of
the plaster board.

It's easier to drill neat holes in the timber panel after cutting a large
hole in the plaster board to bring the cables through. The timber panel
should also give space to fix clips on the cabling so they are more
difficult to pull out of the housings for the equipment. The timber panel
allows you drill individual holes for each cable, if you wish, so they are
neatly spaced and clipped along the length of the equipment housings.
