Receiver Housing and Back Plate
The receiver housing surrounds and protects the base plate and connectors. It contains
knockouts that can be removed to accommodate a raceway, if desired. The metal back
plate is attached to the housing, and contains two knockouts that can be removed as
necessary to accommodate conduits. The housing has tabs that insert into slots in the
dome. A 1/8 clockwise turn secures the housing to the dome.
