I need to build a narrow trolley, say 30cm wide and 100cm deep 74cm high. to sit on four trolley casters.
It would sit behind a sideboard and be pulled out to change or examine its contents, probably liquor.
I want it to be affixed to some kind of rail, perghaps two. One near the top and one at the bottom. Something like an alluminium curtain rail I suppose.
I just can't pin down a sensible description to find a source.
