I'm looking for leg levelers to pair with a 4ftx4ft CNC table I just built. I happen to have two full sets (8 total) of the levelers that have a small (about 1/4 inch) ledge on them that according to hype keep the weight on the leveler, not on the attachment screws. The four legs on my table are 3x3 laminated red oak.

That little ledge that fits under the leg - that puts all the weight on the edge of the leg, not in the center, which seems somehow iffy to me. Am I over-thinking this? Should I put TWO leg levelers on opposite faces of each leg? Total weight including CNC will be about 300 lbs, well within specs of the levelers and the oak legs I would suppose.
