Extron EWB 103 (part number 60-454-03) — white three-gang external wall box, part of Extron's earlier EWB part numbering and now retired.

Use this enclosure when a three-gang Extron plate has to go onto a wall surface rather than into it. The steel box carries the faceplate and gives it 2.50 inches of working depth behind the front opening, so connectors, adapters and a service loop all fit without strain. Cable can arrive through surface raceway via the end knockouts, or through the rear opening from inside the wall. The rear panel includes a PEM #6-32 insert and a grounding screw ships with the box.
