This is an piece of curtain hardware that is hung from a batten and a drape leg is hung from it. It has a central pivot point that allows the leg to rotate (other than hanging in line with the batten) and be positioned at an angle for better masking.
The photo shows a rotodraper intended for use on a traveller track, so the leg can be moved on-offtage as well as pivoted.
