Has anyone ever mounted a hangboard on a structure like this one? I found some hardware online that would clamp onto the square beam, but I’m worried that bolting the hangboard onto one horizontal axis wouldn’t be stable. I was thinking of building a larger frame out of 2x4s bolted in a vertical position to mimic studs in the standard over-the-door scenario. I don’t like the idea of drilling holes in the beam so that makes it a bit more complicated. If anyone has experience with a similar situation I’d love to see what solutions you came up with.
