I would like to run some speaker cable up the corner of the room.

Ideally I would like triangular section or "quarter circle" (that is a

My Google skills don't seem to be up to finding any, and Wickes and
Screwfix don't seem to stock any.

Is the answer to use square/oblong profile (which won't look quite as
neat) or is there a supplier hiding from me?

Quadrant trunking.
As manufactured by D-Line, for one.
