Doorbird 423860735 Flush Mount Back Box Intercom

Product Description

The DOORBIRD 423860735 is a flush mount back box designed for use with the D21DKH video door station. Constructed in stainless steel, this back box provides a clean, recessed installation profile by housing the door station unit within the wall surface. It is a purpose-built accessory intended for intercom system installations in residential and light commercial settings. Electrical or low-voltage systems technicians and security integrators are the typical trade professionals who work with this component during rough-in or retrofit projects.

This back box is applicable to flush mount intercom installations where surface-mounted hardware is not desired or permitted by the design specification. It is suited for new construction or renovation projects where wall cavity access allows for recessed fitting of the D21DKH door station. The stainless steel construction makes it appropriate for both interior vestibule installations and covered exterior entry points where corrosion resistance is a priority.

Verify wall cavity depth is sufficient to accept the back box before cutting the rough-in opening. Follow the manufacturer data sheet for precise dimensional requirements and mounting fastener placement.
