  • Patent number: 5484076
    Abstract: A saddle shaped mounting bracket straddles a conventional junction box mounting rail of a grid ceiling system and is used as a support location for hanging a lighting fixture from the grid ceiling. The mounting bracket has a straddle slot extending through the bottom portion of the bracket to allow the bracket to straddle the mounting rail. Threaded studs on the bottom of the bracket provide a means for coupling an electrical junction box to the bracket when the mounting bracket is used at an electrical feed location, or for coupling to other connector bracket hardware when the mounting bracket is used at a non-feed location. Load wires anchored to the overhead ceiling structure are attached to wire holes in the sides of the mounting bracket to provide efficient anchoring of the bracket.
