On a couple of occasions when I’ve been doing kitchen islands that others designed there would be a situation arise where the sink would of course be centered, but due to DW and trash bins not being the same size, we might end up with a 4” door with drawer over. I usually suggest a knife drawer where it’s a big block with slits for the blade. If I knew all this on the front end I’d mount hardware before assembling the boxes. Plus some changes call for drastic measures. By mounting a drill extension or two between an impact driver and the bottom end of this thing, I’ve been able to reach in at arms length to drill and drive screws where there wasn’t enough room to work my wrist.
I’ve used it to work deep on my truck engine As well.
