Apparatus and method for retro-fitting a recessed light fixture into an existing ceiling mounted assembly or penetration

An apparatus for securing a recessed light fixture to a substrate, comprising:

• a plurality of fastening assemblies, each of the plurality of fastening assembles comprising
• a clevis bracket, and
• a clevis hook having tabs perpendicular to and at a proximal end thereof,
• wherein the tabs are rotateably attached to a proximal end of the clevis bracket;
• a can, the can comprising
• a tubular shaped wall,
• a flange attached to a proximal end of the tubular shaped wall and substantially perpendicular thereto, and
• slots adapted to allow each of a gripping portion of the clevis hooks to pass therethrough;
• and
• a fastener for each of the clevis brackets, wherein the fasteners slideably couple the clevis brackets to the tubular shaped wall;
• wherein when the can passes through an opening in a substrate
• the clevis hooks are positioned axially to the tubular shaped wall until the clevis hooks clear the substrate,
• then the gripping portions of the clevis hooks pass through the slots in the tubular shaped wall of the can, and
• the clevis brackets are slideably positioned along the tubular shaped wall toward the substrate so that the gripping portions of the clevis hooks engage a back face of the substrate while the flange engages a front face of the substrate, thereby holding the recessed light fixture in the substrate.
