Bren I have it holding from 5-75lb dumbbells and it holds them just fine.

Damon B. So far I have 3-35lbs and 75 and 90lbs dumbbells on this rack. The rack is rock solid, and all of the weights are easy to access. I do think I'm going to order the 3rd tier in preparation for more dumbbells. I have no complaints about this rack, it does everything it was meant to.
