Mounts to a wallplate with a BNC cutout. The WZ10102 and WZ10104 are just two of the many wall plates this can be used on, just look for the "01" as the third and fourth characters of a wallplate part number (Wxx01xx). Works on any size of coax cable, but requires a soldering iron (EXC7060 to terminate. The plastic threads prevent continuity between the connector shield and the metal plate or box that this gets mounted to.
