A utility floor box includes a body having a horizontal base, first and second longitudinally extending side walls extending from first and second opposed edges of the horizontal base, and first and second laterally extending end walls extending from third and fourth opposed edges of the horizontal base. At least one of the first and second side walls defines a branch opening, and at least one of the first and second end walls defines a duct opening. First and second horizontal support bars extend through aligned first and second support openings in the first and second side walls. First and second vertical support legs are secured to the first support bar, and third and fourth vertical support legs secured to the second support bar. The first, second, third and fourth support legs are vertically adjustable with respect to the corresponding first and second support bars. |
