Hello, I have a dilemma! I am going to be creating a floating wall on a wide chimney breast when I get the keys to my new house next friday. I want wall mount 180cm of besta units underneath the telly but the chimney breast is only 61 inches wide. This would leave 4 and a half inches of the besta units hanging over the edge of the chimney breast. Now I don't necessarily have a problem with this aesthetically, it may even work quite well for my front speakers. My questions are: 1. Is this safe to do? 2. Are there any additional things I would need to do to ensure the safety, or would it be enough to just leave it hanging over? I could always just have 120cm / 2 besta units instead of 3 but it doesn't look as good... Thanks!
