About this detail

Suspension and seismic bracing requirements for a continuous luminaire row hung beneath a structural steel beam and metal deck assembly. Back-to-back strut channels run continuously above the luminaire length, attached to structural beams using Unistrut beam clamps on each side of crossed beams. Three-eighths-inch threaded rods spaced at eight feet on center, and at each end of the run, suspend the lower luminaire strut channel using double nuts at both top and bottom. When hanger lengths exceed eighteen inches up to ten feet, intermediate strut channels with cradle clips and bolts are provided at eighteen inches on center. Longitudinal sway bracing is required at each end of the run, with an optional forty-five-degree Unistrut bracing configuration permitted in lieu of aircraft cable.
