In-Wall TV Box With Flange For Clean TV Install

The Dremica in-wall TV box with flange is designed to hide behind a wall-mounted TV while offering two duplex outlets and a separate path for HDMI, Ethernet, and other low-voltage cables. The recessed design helps maintain a flat wall appearance, which is especially helpful in media rooms and conference spaces. The box also includes a 1-1/2″ ENT entrance for clean cable management. This option is ideal when you need both power and data pathways in an integrated wall assembly for a concrete-wall retrofit or new build.
Low Profile TV Box For Shallow Walls

The Arlington TVL508-1 is a shallow-wall solution designed for 1/2-inch or 5/8-inch drywall depths. With a compact depth of 1.25 inches, it accommodates wall-mounted TV installations without protruding, reducing bulk behind the screen. The package includes a decorator-style receptacle and is well-suited for retrofit projects where wall thickness and finish are critical concerns. Its lightweight, low-profile design helps preserve clean lines in living rooms or home theaters against concrete walls.
Extra Deep On-Wall Raceway Starter Box

Legrand Wiremold’s extra deep starter box is a robust on-wall conduit connector that provides cable management for heavy-duty applications. It is designed for use when wall-internal routing is not possible, such as concrete walls, brick, or tile surfaces. This box works with the wider Wiremold raceway system and helps interconnect raceway segments while keeping power and data paths neatly organized behind walls or along surfaces. It’s a strong choice for projects requiring extensive in-wall or on-wall wiring solutions on concrete structures.
2-Gang Concrete Floor Box System

The Leviton FBBOX-GY 2-Gang Concrete Floor Box System is designed for concrete installations, providing power and data conduit reducers to adapt to a wide range of devices. With a 6.25″ height and two-gang capacity, this box is ideal for rooms that require floor-level outlets with inputs for both electrical and data needs. A separate finish plate can be added to ensure a seamless look once installed in concrete floors or slabs. This option expands the utility of concrete spaces, such as home theaters or conference rooms, where floor-level access is preferred.
Recessed Single-Gang Box For Wall Mount TV And More

The Magaliyo recessed single-gang box is crafted to hide outlets and keep wall sockets flush with the surface for a cleaner look. It supports GFCI and standard outlets and ships with compatibility for wall-mounted TVs, antennas, and cable services. The recessed design helps align the box with the wall thickness and is suitable for both new construction and retrofit projects on concrete walls. The product emphasizes a flatter finish and color-matching flexibility for a cohesive room aesthetic.
In Wall Cable Management Kit With USB Ports

The ZEXMTE in-wall cable management kit includes two standard AC outlets, two USB-A ports, and low-voltage pass-through, designed to power a TV or media devices while concealing cords behind the wall. Installation is simplified with mounting hardware and templates, plus clips that secure the recessed outlet kit to concrete or drywall. The kit emphasizes space-saving and tidy wall aesthetics, making it a practical choice for modern living rooms where minimal cord visibility matters.
Buying Guide: Key Purchase Considerations
When choosing the right outlet box for a concrete wall or floor, consider depth, mounting method, and the type of connections you need. In-wall solutions are ideal for TVs and media centers where a flat wall look is essential, while floor boxes suit rooms where devices or outlets must be accessed from the floor level. If you’re routing through concrete, ensure the product supports through-walls, data pass-through, and low-voltage management. Look for UL listings and compatibility with your existing raceway or conduit system. For retrofits, ensure the unit fits the wall’s thickness and can be installed with standard tools and minimal demolition.
Compared to standard wall boxes, concrete-oriented options often require:
– Greater depth or special mounting flanges to anchor into solid substrates
– Dedicated connectors for power, data, HDMI, Ethernet, and USB
– Proper grommets or ENT entries to seal against dust and moisture
– A clean finish plate or wall plate to match your room’s décor
Bottom line: Match the box to the installation surface (concrete wall vs. concrete floor), the intended devices, and the preferred finish. If you need both power and data in a single, discreet setup, a recessed in-wall kit or a floor box with data reducers provides the most cohesive result for modern interiors and home theaters.
