This screen is a screen that is mounted on tripods and placed somewhere. It is not primarily intended to be hung on a ceiling/wall.

Is that somehow feasible? It certainly is.
Whether it makes sense? Probably not necessarily.

Presumably this idea comes about because of the price difference to "proper" wall/ceiling-mounted screens. :-)

The necessary dowels and screws depend on the wall (concrete/wood/stone/gypsum/...) to which the whole thing is to be attached somehow and on the weight that is then suspended from it.
