This large hex bar is fully "rackable", meaning it will fit in any power rack with the sleeves sitting outside the rack so you can load them without interference.
The included collars fit the 1.91" sleeves, which is a smaller size than typical olympic bars with 2" sleeves. Other collars will not tighten properly on these sleeves. These collars are a specially sized version of the Roepke Aluminum Collars.
