    High Quality & Fits Rogue

    I have a Rogue Monster rack. Wanted to upgrade my standard Rogue J cups to something nicer without breaking the bank. Rogue’s Ghost rollers are too expensive for my budget and I don’t trust Titan’s quality. These hit the sweet spot. The quality is perfect, they aren’t overly heavy, the rollers work great, the protective padding feels solid, and the magnetic pins are the cherry on top. First B.O.S. product. I’ll definitely check out more of your guys’ stuff in the future.

    BOS jcup roller, awesome!

    One of the best purchase. I always lift heavy and aways wanted a perfect middle alignment of the bar. i can easily move the bar with over 300 pounds of weight on it.

You nailed it—being able to easily move the bar with perfect middle alignment, even with over 300 pounds loaded up, is what these are all about.

    Great quality and value

    I did my research. These roller j cups are great value while not compromising quality. I wish that they some kind of pin like 1 inch ones so they don’t move at all. Ones for 5/8 holes don’t have the safety pin.
