A powerlifting bar that holds the weight closer to your center of gravity allowing for heavier squatting variation. I have a 2x2 squat rack and it fits perfectly fine so your power rack more than likely will accommodate this specialty bar.
It's stands 16 inches tall and 7ft in total length, see pics.
Fits standard Olympic plates
REGULAR BARBELL CLIPS WILL NOT WORK
Aggressive knurling
No bends
It's been used so don't expect a shiny bar
