Recessed electrical boxes position power plugs, low-voltage cables, and connectors inside the wall cavity, helping TVs and other wall-mounted equipment sit closer to the wall with less visible wiring. Many configurations include a voltage separator and a trim plate, supporting organized power and signal connections with a finished appearance for retrofit or new-construction installations.

Choose a single-gang box for a compact installation with one device, a double-gang box when you need room for multiple connections or components, and a larger configuration for several devices or combined power and low-voltage wiring. Also consider the wall space, retrofit or new-construction method, cable volume, and whether a recessed design or voltage separator can help keep plugs and connectors behind the finished wall.

Retrofit electrical boxes are designed to install in finished walls, using mounting wings, clips, or dogs that secure the box to the wall surface without direct stud access. New-construction boxes typically mount to a stud or framing member before drywall is installed, while some Arlington electrical boxes support either installation method.

Choose a box that matches the wall thickness and construction method, noting that some retrofit models adjust from 1/4 to 1-1/2 inches, while others use mounting wings, dogs, spring clips, or stud-mounting holes. For new or retrofit work, also consider the gang size, metal or nonmetallic construction, available space for connectors, and whether a voltage separator is needed to keep power and low-voltage wiring in separate sections.
