The Extron EWB 112 external wall box is an enclosure for US two-gang wallplates. The EWB 112 is designed with sufficient depth to house faceplate wiring and accepts cable runs from a surface-mounted raceway or rear wall space. It mounts two-gang wallplates such as the Extron MLC Plus 100 MediaLink® control panel onto a wall or other flat surface. The EWB 112 is available in a durable white finish.
