Shallow trunking not too wide

[ban-all-sheds]

Has anybody ever come across galvanised trunking that's about 90-100mm x ~40mm?

38mm floor trunking is an ideal depth, but can't find any as narrow as 90-100mm....

Sizes are given on the "price list" http://www.unitrunk.co.uk/catalogue/floor-trunking/?expandable=5 not sure if it is what you are looking for but they also do a bespoke service.

Yo - looked at them.

150 x 38.

I only need less than 2m - don't think that custom would be realistic...

If you only need that little, it wouldn't take all that much effort to cut down, say 100 x 50 would it?

Alternatively, have you tried thinking laterally and searching for things other than electrical trunking (albeit I can't think of exactly what off the top of my head!)?

Have you tried asking a local fabricator to fold some for you?

I can think of two ways to cut it down.

One would leave me with just 2 sides, no back, and no way to fix it to the wall.

The other would leave me with a 'U' shaped channel with no lip on the sides for the lid turnbuckles to engage with.

I can't think of a 3rd way which would avoid both of those problems.....

Yes, but not a great deal. (Nor I).

I didn't think about it too deeply, but (in relation to your second option) was envisioning that one could probably devise an alternative way of attaching the lid. Is this going to be buried in a wall?

You could try asking, it would only take an e-mail or phone call.

Sort of.

It's hard to describe, and I don't have time right now to draw it, but the depth is limited because at the top it can go no deeper than a stair riser, and the width is limited because lower down it will be against the end of a stud wall. It will end up with a removable wood panel over it.

That's quite true.

Fair enough, and that also answers what would have been my follow up question!

I still think that, if you can't find any easier solution, you could probably cut down a 100 x 50 and then use your ingenuity to find a way of attaching the lid.

[ban-all-sheds]

I'm sure I could.

Forgive me for feeling I'd rather not have to.

Start with 2 lengths of 100 x 50. cut the 'top' off one, and the 'bottom' off the other. Overlap them to the size you want, drill through both, and pop-rivet them together.

Or just cut the sides down, and fix the lid to the underside of the wooden panel which will cover it.

Or just use wood for the whole thing and claim that the cables are not concealed in the wall, they are in surface mounted wooden trunking.

I'm sure I could. Forgive me for feeling I'd rather not have to.

I can sympathise with that feeling. However, I've learned through plenty of bitter experiences, that it is sometimes arguably more rational to "simply do" the non-ideal thing that one would rather not do than to expend considerable amount of time and energy (and sometimes cost) in searching for a more ideal approach which one would prefer!
