This electrical box is usually called a 1900 Box because that was the original part number from Bossert almost a hundred years ago. It is the most common box used when a simple SwitchBox is not large enough. The part number shown below is only one of many configurations and you need to ask for the size of the knockout (determined by the conduit size) and if the user wants a small (1-1/4"), a standard (1-1/2") or a deep (2 1/8") box. The user also has to specify how it will be mounted: stud ears, etc.
"Put a 1900 Box at the end of the run and install a duplex RS cover."
