Here is a custom pull up bar we modified for Andreas. His ceilings are shorter than 8 ft which made drilling another set of holes at 12″ the perfect bar height for Andreas. Here is what Andreas wrote:
“The 12” setting is perfect! Plenty of room for my head, and my feet just clear the ground in a dead hang.
Also real nice that the bar is wide enough to slide the hangers for our Primal 7 off to the side when doing pull-ups.”
