About this detail

An overhead Unistrut framing assembly bypasses a ductwork or mechanical obstruction using slotted Unistrut channels secured to the structure above. Unistrut P1000SL channels attach directly to the upper structure, supporting a horizontal Unistrut frame joined by P1325 ninety-degree angle fittings at each interior corner. P1001 vertical channels extend downward from the framing, spaced at forty-eight inches on center maximum, and are stabilized by P2458-18 tubular knee brace supports. A finished ceiling and trim plate interface with the vertical drops per architectural specifications. Field coordination is required to route uprights and diagonal bracing clear of piping, ductwork, and lighting.
