I have to feed some cables through a 1" (or thereabouts) hole in a cabinet. In normal use only one side of the hole will be visible and I'd like to make it look as neat as possible, so I need something tubular with body that fits through the hole and a lip that hides its cut edge.
The annoying thing is that I've done this before, but it was years ago and I can't remember what I used, though I think I bodged it up from a plastic waste pipe fitting (I recall having to drill a hole in the "lip" part, which was solid).
Searches online and rummaging in DIY shops haven't turned up anything suitable, so any suggestions will be very welcome, Thanks.
