Good point on the slip over style, I a see your point: Not all racks have thru-holes on top.
Re hole alignment, an oval or slot on the pull bar could mitigate hole alignment issues.

In reply to Jeff Popoff.

If it’s a rack where the top frame has holes, and the holes are spaced just right so you can get both bolts in (you don’t want it to rotate), and the pull up bar is too short rather than too long, I can see how it could be retrofitted. But many racks are going to not meet at least one of those specs. I’m thinking if it can slip right over the top of the rack and uses no holes at all, it ought to fit just about every rack.

Why brackets at all?
A 47″ pull-up bar can be affixed using different width bushings and 6″ bolts to fit larger width racks.
The bushings would carry very little lateral load, and would properly keep the bolts in shear (their strong axis) and out of bending moment (their weaker axis).
