The deadweight comprises several support members and support frames which define a general cubic shape. A plate is positioned on each face of the cube, with cement filling the center of the deadweight to provide additional weight, stability, and support. Fork lift sleeves are provided to allow easy positioning of the deadweight. Each plate comprises a plurality of apertures for fitting a 12'' or 20.5'' box truss. A large rectangular aperture is positioned on each side plate, permitting users to reach into an enclosure to bolt the box truss to the desired plate. The bolt apertures are adapted to mount a box truss flush to each plate. A leveling mechanism is provided to ensure the deadweight and box truss will be stable even on uneven ground.
