ABSTRACT:
An electrical junction box to be used when supporting a relatively heavy hanging load from the underside of a joist/beam at an installation site. In one embodiment a slotted pancake dish internally supports an arcuately displaceable bracket both of which have coincident slots through which to receive fasteners by which the load is to be supported. A removably disposed lead box in which electrical leads are received extends normally upright to the plane of the pancake dish and is adapted to he positioned thereon off center in communication with an opening through the dish. A partially circular shell section can optionally be utilized by being removably secured on the pancake dish opposite the lead box so as to cooperate with the lead box when utilized in forming an externally appearing cylindrical canister-like configuration. A second bracket vertically depending within the sleeve of the shell section is securable at its top portion to a joist/beam and at its lower portion receives the pancake dish and load via bolts secured thereto. The second bracket provides for angular adjustment so as to compensatingly accommodate various beam pitches. Indicia along the exterior of the shell provides guidance in cuttingly removing portions of the shell in correlation to the pitch of the beam in order to receive the beam intervening between the shell and lead box while affording axially vertical orientation of the cylinder. In another embodiment, a pancake dish and electrical lead box are integrally joined as a unit for direct joist mounting or can be utilized with the second bracket as before. An optional horizontal support plate is disclosed for use in combination with the second bracket for supporting the load.
