I got a power rack this weekend and I dont know who made it. I want to know if there are any options I could get for it. It has spring trigger j-cups and the ends of the safety bars are spring loaded also. Its pretty big, 8 feet tall and 4-1/2 feet deep. It seems a little older but very heavy duty. Its the same rack that John Meadows used in the videos in his "bigger triceps" live spill, if that helps at all. Any info would be great, thanks.
