STEP 5 – Install 4” Octagon Enclosure Mark the center of the 2 x 4 (@12”), and draw a line Notice the screws that stick through the bottom of the box. These screws are for securing the Romex cable that goes into this box. Use a drill to make holes in the 2 x 4 to accommodate these screws. Mount the 4” Octagon Enclosure with the 4 screws.

STEP 6 – Install Plastic Enclosure Measure and mark a line 1” from the right end of the board. Position the plastic box so that the box sticks over the edge of the board by ½”. In a house wiring situation, this will allow for ½” sheet rock to be installed around the box. Nail enclosure in place using the nails provided. Be careful not to drive nails in to farr as the box may break (it is made of plastic).

STEP 7 – Install Cable Clamp Remove ½” knockout from the metal enclosure. Be sure to remove the right one. Install Cable Clamp with the retaining nut inside the box.
