A support hanger system adapted to hang away from a top chord of a truss assembly using the upwardly facing planar surface of the top chord as the support surface for the downwardly extending support hanger. The support hanger assembly utilizes an elongated threaded member extending away from an operatively connected cross member. The cross member is oriented in transverse relation to the axis running along the length of the elongated threaded member. The cross member is adapted to fit through an acceptance slot extending through an upper base plate structure of the top chord such that the operatively connected threaded member extends downwardly from the upper base plate structure between downwardly projecting leg elements on either side of the acceptance slot. A channel support member adapted to reside between the leg elements may be disposed at a position below the cross member.
