Model OH601S Surface Backbox Shown Right
They are among our most popular surface mounting boxes, and are used with a variety of intercom entry lobby panels, and remote intercom stations, to allow they to be surface mounted on the finish of a wall. Typically, wire access is from the large opening in the rear of each box, but the installer can drill or punch knockouts as needed, in the field.
Theses boxes are finished on top, bottom and both sides, and are partially open in the back to allow for wire access. They have inside mounting holes to allow for mounting right to the finished wall surface.
They are typically used with the ES612, AM612 and AM642 series lobby entry panel stations, but can be used with other stations as well. The OH600S can also be used with the IR150SS area of rescue assistance remote station(s), when mounted horizontally.
