what a nightmare when I open the box ! the bolt , washer and nut be scatter all over the box . as expect , most of the piece be miss . I be also not able to find any square end Cap . the left and right beam be also scratch and the base of the beam be dent . I be not even sure if I be able to fit in the base end cap . these be just some of the few thing I have notice upon quick inspection . not sure what else be miss or wrong with the rack . I be return the item . what a waste of my time .
