Will 3 - 16" on center 2"x4" wall studs support 600 pounds when anchored 32" apart. I want to set up a pull up bar in my garage strong enough to support 2 people simultaneously. The plan is to anchor 3 steel rectangles, which will have the pull-up bar 30" of the wall, with the load spread between every other stud. I plan to use 3 lag bolts per vertical support.
There are other variables needed in order to know. Do you have a picture of the area? how far from the support wall will this pull up bar be located? The vertical force is important but so is the distance away from your support wall Torque = force x moment arm.
