Doorbird 423867529 Surface Mount Back Box D21DKH-V Ss

Product Description

The DOORBIRD 423867529 is a surface mount back box designed for use with the D21DKH-V video door station. Constructed from stainless steel, this back box provides a secure and weather-resistant housing solution for flush-free wall installations. It serves as a structural mounting enclosure that supports proper positioning and protection of the intercom unit. Licensed security and low-voltage installation professionals typically specify this accessory when a recessed or in-wall mounting configuration is not available or practical at the job site.

This back box is intended for use in residential and light commercial intercom installations where the D21DKH-V door station requires a surface-mounted deployment. It is suited for exterior entry points, gate stations, and building access locations. The stainless steel construction makes it appropriate for covered outdoor environments where corrosion resistance and structural integrity are priorities.

Key Features

• Surface mount design for installations where in-wall recessing is not feasible
• Stainless steel construction for corrosion resistance in exterior applications
• Matched enclosure geometry for the D21DKH-V video door station
• Single-unit packaging for individual installation projects

Compatibility

Designed for use with the DOORBIRD D21DKH-V video door station as a surface mount back box accessory.

Installation Notes

Installation is typically performed by a licensed low-voltage or security systems technician. Power down the door station system completely before mounting or wiring any components. Ensure the mounting surface is structurally sound and that all conduit or cable routing complies with local low-voltage wiring codes. Do not overtighten fasteners against the stainless steel enclosure to avoid distortion of the mounting interface.
