James, I'm sure of the configuration you're interested in, but we do carry, in stock at Lowes a metal pegboard that measured 16"x16". $9.98.

Interesting... When I built my hanger that wasn't an option. My bases are 6 to 14 lbs and I currently cluster them together
I have the supports at 16" centers into wood studs with 3" drywall screws. I should be able to do chin ups on it... the masonite is a weak link.
