Hoping this is ok to post here (as it’s technically a ceiling and not a wall question!).
I have four 5mm metal plugs in my plasterboard ceiling which used to hold a 10kg projector screen (two plugs on each side which are around 40mm from each other, with around 2m between each side). The screen broke and the manufacturer sent me a replacement which has a hook on each side for ceiling mounting, rather than the traditional bracket which was on the older model (which could attach to screws).
I have bought a 5mm screw hook for each side, but how safe do you think it would be to spread the 10kg weight across these two screw hooks, as opposed across four screws which I previously used? Asking as I’d really like to avoid remounting in new plugs or reinforcing the ceiling.
