I look for hour in all the wrong place . I think I need to go to the standard weight-lifting site to find a good dumbbell rack , but I be wrong . prior to this , the best price I find be $ 120 . I decide to look at Amazon for grin , and find what I be really look for . the product be solid , it ship fast , and it be simple to assemble . ignore the ciritial opinion ; they fix all the problem . the nut and bolt be all on a piece of cardboard with shrink-wrap plastic around it . do not waste you time look for a better deal -- this be it !
