Extron EWB 104 (part number 60-1164-03) — the white four-gang external wall box in Extron's EWB Series, sized for dense wallplate assemblies.

Where a room needs four gangs of AV connectivity but the wall cannot be cut, this enclosure carries the plate instead. It fastens flat to the wall, spans 8.2 inches across the opening and holds 2.50 inches of depth behind it — enough that connector bodies, adapters and a service loop all sit comfortably once the faceplate is screwed home. Cable enters through raceway knockouts on the ends or from the wall cavity through the rear. A grounding screw and PEM #6-32 insert are part of the kit.
