I was asked by my customer to design a "floating shelf" that would be quite large; 82" long x 12" deep by 3" thick. I made it from 3/4" birch ply so it had a lot of weight to it. It was also going to support stemware over a bar and mugs on top. Needless to say the hardware needed had to confidently support that. This bit of hardware did the job perfectly and I would recommend it 100%. I excised the drywall from the wall exposing the 2 x 4s so my screws were properly anchored. The holes drilled into the hardware were perfectly spaced so I could grab all four of the studs and could just about hang my 200 body on that metal. All in all it was a very successful project primarily due to this piece of hidden hardware.
