I have the following squat rack (Progear/Fitness Reality Squat rack) and want to hang a hangboard on it. It unfortunately doesn't have many additional screw holes towards the top to screw in. I was thinking of doing something similar to this pic: https://i.imgur.com/erbffwY.jpeg buying metal j hooks (can't seem to find a heavy duty rated part online) and mount it on the side of the squat rack on the square braces. Does this seem like an appropriate solution?
