The ones I'm after are essentially just a metal bar sticking out at right angles from the wall (or the mounting bar to which they're fixed) with the end just turned up a little. The total length would be, say, 5cm with 3cm straight out from the wall and 2cm sloping upwards slightly.
Do these have a special name? Has anyone seen a supplier who sells them? Individual hooks or a mounting bar with 6 to 10 hooks would both be OK.
