The MUD-2G is an extra wide 4" mud ring with square corners for mounting active electronic devices. The MUD-2G was designed to make the installation of the FSR Flex control system and HDBaseT wall plate transmitter easier. The mud ring will fit both formed and stamped 4" square electrical boxes manufactured by the leading electrical part suppliers. The mud ring is available in 1/2" and 5/8" models. Both models feature a unique open frame design that increases the usable area over the standard stamped 2-gang cover.
