I have to cover about 2-3m of cabling going into a wall mounted rack. There
are about 18 cat5e cables. I'm looking at just some basic trunking, and
from what I can see, mini trunking, is the most common. However, I cannot
work out the correct dimensions. I often see them described as: 10mm x 8mm
x 3m, 18mm x 9mm x 3m, 16mm x 16mm x 3m, 25mm x 16mm x 3m, 40mm x 16mm x 3m,
40mm x 25mm x 3m. Maxi trunking is larger, but less common.

Which is the width and which is the depth? I've seen some trunking (slotted
edge, which can bend) which is very deep but very thin - that's not what I'm
after. I'd like a nice wide bit of trunking. If necessary, I'd use 2 bits
next to each other if I can't fit all cables in it.

Any idea of the size trunking I would need to put in about 18 cables? Any
where online that would do these sizes, and can delivery next day (I need to
do it on Satuday). So far B&Q don't have maxi trunking, Screwfix don't
either, BES have the sizes above (mini) but no maxi, TLC-Direct do maxi, but
don't appear to have any of the corners (I need one or two corners).
Anywhere else to try?

Also, can anyone explain how the corners etc works in trunking? Do they
just go over the cover, or are they mounted to the wall? If they go over
the cover, how do they stay there?

Thanks

Trunking is cut so that the inner parts of the corner meet. The corners
are clipped onto the trunking or for an external corner onto the cover.
The cover will have to be short of the end of the trunking - see the
corners for how much. It may be helpful to use short (15mm or so)
pieces of cover every 18 inches to hold the cable in the trunking while
feeding it in before finally putting the cover on.
