We use an IKEA Fridans blind as a projector/projection surface. It is mounted on the ceiling and we can lower it when we have a movie night.
So to get the adjustment rod out of the way when the projector surface is rolled up, we mounted the holder just at the end of the swiveled adjustment rod - clips in and is hold in place.
Needs a 4mm screw to be fastened on the wall or ceiling.
