Extron EWB 104 (part number 60-455-02) — black four-gang external wall box from the legacy 60-455 part series, now retired by Extron.

Four gangs of AV connectivity on a wall that cannot be opened up is exactly the problem this enclosure solves. The steel shell fixes to the wall face, spans 8.2 inches of faceplate width and keeps 2.50 inches of depth behind the opening so connector bodies and slack cable are not fighting the plate. Surface raceway enters through the end knockouts; cable from the wall cavity comes in at the rear. A PEM #6-32 insert and grounding screw are supplied with the box.

Key Capabilities

• Steel enclosure at 4.50 in H x 8.2 in W x 2.50 in D (11.4 x 20.8 x 6.4 cm)

Where It Is Used

Auditoriums, studios, dark-finished boardrooms and control rooms where a black enclosure disappears against the wall treatment. Also a like-for-like replacement on older Extron installs predating the 60-1164 part series.
