They fit on both standard and specialty bars. The only downside is they don’t hold very well if they are dropped like from an axle press or oly lift. They’re pretty pricey, but the time you save not having to take them off to load plates makes up for it. If you have a non climate controlled gym, bring them inside during the winter. The rubber will shrink and crack then they are nowhere near as useful as they once were.
