the shipping box I receive be not really in good condition , some washer and part be fall apart . its packaging be just average . I do not believe you can assemble this stand in 30 minute . I time myself and it take I good 90 minute with help of my wife once in a while -lrb- hold bar for I to align hole and tighten nut -rrb- . its bar and connect bracket be pretty heavy for one hand to hold while the other hand tighten the hex nut , and if you do not have a third hand , you should use a nut driver or something to lock the Allen wrench stationarily . you should prepare a 9\/16 '' or adjustable wrench , a small nutdriver use for extend the provide Allen wrench , a rubber hammer -lrb- or equivalent tool -rrb- to slightly tap steel bar hole align . bracket be build with very tight tolerance that it be not easy to fit together without tap they in place . you should also arrange supply 16 bolt in 3 different group -lrb- different length but go with same washer and nut -rrb- to prevent mistake of wrong bolt . there be quite a few turn trip and drop but no scratch , no bruise , no blood . finally , it be assemble in good shape , no miss or extra nut and bolt , and with big relief ; I ' m happy . the design be solid with durable hardware and the stand look great and robust . with bf 552 dumbbell on top , they together appear bigger than I expect . do not discourage yourself not to purchase it because of fear of long assembly time and installation difficulty level . the instruction and drawing be very clear , easy to follow and simple . give yourself patience and care , you will enjoy it
