Never used a french cleat to hang a cabinet but I am about to do my first one. Because of the size and weight issue I built the unit as two pieces. I was a little concerned about the wife and I being able to lift a 7' length of cabinet over a washer and dryer and hanging on the cleat.
Now I am concerned about getting the two pieces to fit up snug together. I can imagine a lot of reasons that they would not fit perfectly together. Obviously I could screw the sides together once in place but that is sort of last resort. Just curious if any had done this and might have some advice?
Wondered why no one had replied. Seems I was typing this in the shop and never sent it.
OK here is a photo. If you look close you can see the right had side is a separate part. It's held by clamps at the moment to finish the dry fit.
