RE: mounting a european mount - HELP
Check out the selection of hangers at the local hardware store. Get one that will "hang" on to the head of a screw or nail. To make it more secure, slide a washer over the nail or screw before attaching it to the wall. Buy a hanger that will hang over that washer. Attached the hanger as close to the top of the backboard as you can. I hope all that made sense.
