5. Concealed Conduit Mounting.
Refer to the introduction, warning message to installers, and basic installation instructions
The concealed conduit mounting method may be useful when an existing junction box will not
accommodate the basic installation. This installation configuration requires the use of a Model NB
Knockout Box and a Model CC Adapter Plate. Use the pair of 6-32 or 8-32 flat head screws to
mount the plate on the existing box. Install the insulated bushing in the rear of the knockout box
before attaching the box to the adapter plate with two 10-32 x 1/4" round head screws. The
insulated bushing protects the power leads that pass through the center hole in the CC Adapter
Plate and the center knockout of the WB box to the horn. (Diagram G).

holes of the projector. If it is desired to use either of the projectors when the horn is flush
mounted, it is necessary to install the Model SF Plate instead of the FG Grille. (Diagram H).
