I have a very heavy 7ft screen (motorised). Can anyone recommend suitable fixings (I have the brackets, need advice on wall plugs etc) I have solid breeze block (old style, not thermolite) and a plaster finish. I don't think that standard wall plugs will be enough. Can anyone suggest some UK retaillers who might have something suitable? I'm also thinking about putting a batton behind the brackets (wood) to bring the screen off the wall by 1.5" so I can have a picture / painting on the wall. Any ideas?
