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.
