Extron EWB 101 (part number 60-452-02) — the black one-gang external wall box under Extron's earlier EWB order code.

Extron has since moved the black one-gang box to a newer part number, but 60-452-02 remains the code on a great many drawings, asset registers and as-built schedules. Ordering against the original code avoids the small but real risk of a mismatch when an existing wall of boxes has to be extended. The box itself is the familiar EWB design: pressed steel, surface-fixed, 2.50 in deep so a one-gang faceplate has room for its wiring, with knockouts for raceway cable entry and an open rear for cavity runs.

Where It Is Used

Established AV estates being extended or repaired — university buildings, hospital departments, corporate campuses and government facilities where documentation still calls out this code and a like-for-like box is required.
