I must say that I be quite impressed with the build quality of this rack . it surpass some of the stuff that I have see in the gym over a number of year . right now , I use it to support dumbbell from 5lb to 20lb in 2.5lb-increment . also , the rubber footing edge make it a good choice for tile or equivalent hard surface without cause damage . I really like this rack and it be highly recommend on my part !
