The FL-200 Series consists of 2 box designs. The 3" back box has 2 single gang compartments of different volumes and is a perfect 2 trade box. The compartments are independent of one another so that the smaller compartment can be used for high voltage while the larger one is used for low voltage connections.
The 4" back box has a single Decora opening for data or power connections on one side and on the other side there are two different internal brackets available. It ships with a bracket that mounts standard size electrical plates that accommodate a 2 gang plate or can be split into 2 single gang openings with isolation. The second bracket, the MMS-FL200-4, ordered separately, has a 2 gang opening for mounting modified digital media devices that require more room behind the plate.
The covers meet UL scrub water requirements for tile and carpet installations and feature easy tool free access as well as a fold down cable exit door which allows the cover to be closed with cables exiting the box.
