It's made for a home gym, so for it's purpous it fine. But if your going to place a ton of weight on it and stack weight out to the end of the holders, I wouldn't use it. The weight holders are the screw on type. I'd go for one where the holders are all solid.
So a commerical one is what I'd go for. But for a home gym, it's fine.
This item is used to store weight plates for one inch holes weight plates.You take the weight plate off of the weight rack and place them on the barbell equally.Clamp the weight plates down so that they don't slide off.Then you proceed with your workout.
