Extron Flex55 100 Mounting Kits install onto Flex55™ enclosures and EU junction boxes. Each kit includes a trim frame and mounting bracket for a one- to four-gang EU junction box or Flex55 enclosure, and each opening holds one full-size or two half-size Flex55 or EU modules. They are compatible with EU modules such as Extron DTP T EU 4K DTP transmitters and EBP eBUS EU button panels. Flex55 112 is a double-size single-opening mounting kit compatible with products that include the Flex55 AC+USB 130 US power module. This model accepts up to four half-size modules or a mix of up to two full-size modules. Flex55 112 is directly mountable into walls or furniture when a Flex55 or EU junction box is not required. Flex55 100 Mounting Kits are available in a black and/or white finish.
