I just get this dumbbell rack and put it together myself , within one hour . Ok , so my hubby have to make a little adjustment to it because I build it a little crooked , lol . I be absolutely please with this rack . it hold all my dumbbell , 20 's , 15 ' 2 , 12 's , 10 's , 8 's , 5 's -lrb- 2 pair of 3 's -rrb- , 2 's and 1 's . I would just like to say to the reviewer that say they can not store they smaller neoprene or vinyl weight on this rack , I lay mine across the rear top rail . this work great for now , since I have available space . if I ever fill it to capacity , then I 'll have to find another home for the smaller weight , but for now , it work , and it be a idea for everyone else .
