Keypad and Thin-Metal Doorphone Faceplates are the same size for a perfect match. They both use single-gang boxes. They will be mounted side-to-side or otherwise as might be convenient. Shown here Doorphone plates in colors and finishes that match keypad finish: stainless steel, black and white.

Thin-Metal Faceplate Doorphones as well as Access Keypads can be mounted in standard-size Backboxes on a post or a goose neck (as shown above). Very convenient in gated driveways used by both visitors and homeowners, and the like. Paint your Backbox and post or gooseneck in matching color: aluminum, black or white.
