Re: 24" vertical poles on a DIY pull up bar?

Yep. I'm sure lag screws up into the board through the flanges would work. But I have been burned too many times trying to take short cuts so I just used the bolts. The washers are on there to give a little more surface area for where the bolts meet the flanges and even the load out on the bolt head.
