guy this be a solid dumbbell rack and a deal for the price . well package and solid when build . no worry as this tight rack can handle the weight . I give this five star for quality and value . the only very minor ding I will give it be the bottom channel of each tier be not very deep and the larger dumbbell hold on solid but catch the hex dumbbell on one if the inner angle . the dumbbell be still secure but not rest on the flat portion of the dumbbell . if the channel be about a inch deeper the larger dumbbell would rest on the flat side . Ok for you rubber hex people here be what you can put on this rack . I have 20 's ,25 's and 30 's on the top rack and they barely make it on . tight but manageable . I have 35 's and 40 's on the second rack with some room . you could possibly squeeze only one 45 on this second rack but you would not have enough room to carry the third rack . so I have 45 's and 50 's on the bottom rack again with some room . that be about it if you be buy rubber hex from 20-50lbs .20 -50 lb be right and anymore will not fit . something to consider be that the lowest rack be pretty low and if you have the space you may be better off with a two tier so you do not tingle the spine so much when you bend over . if you be tight for space like I , this be the way to go and for a steal of a price .
