The Hamilton should be ok mounted at the 112 mark. Do the maths.Thanks for the suggestions.
The hamilton would be too short for a 2x12 vertical cabinet.
I was trying to stay away from carrying yet another thing in my backpack but the wedge may be the only solution although not one that may work for all applications.
I'm thinking that for it to be a universal tool with some safety margin, it would have to hold up to a 150lb cabinet and head.
There would be less force on the angled front but On Stage Stands doesn't publish any max weight specifications.
I'll send them as email; but the ones that bolted to the bottom front of the cabinet are still my first choice!
Edit: I could just fab one in my shop but there are at least a half dozen projects that need to be finished first. I guess that there wasn't that much demand for this product.
