I receive this stand and like another reviewer , have some difficulty with the installation . the instruction be brief and the explode diagram be not clearly marked or number . many of the screw be 2.75 inch , but four of they be only 2.5 inch - make sure when you install , that you put the correct one where they belong ! once you have some of the piece together , you get a idea of how the assembly will go . the part themselves all seem like a very durable steel . the build quality seem good and once install , this make a excellent companion for the dumbbell . the stand weigh about 55 pound without the dumbell and stay rigid when the dumbell be install . you may use the plastic wheel for a move stand or choose adjusable stationary caster . the plastic wheel feel cheap and have a lock mechanism which will break if you be not careful . overall , this appear to be a solid product which be a great place to keep you selecttech 552 dumbbell . if you can accept the cheap wheel , poor instruction , and the expense -lrb- $ 135 + -rrb- , this be a very good stand .
