The Arlington TVL508-1 is crafted for shallow walls, offering a low-profile solution suitable for half-inch or five-eighths-inch drywall. Its compact 8-by-5 inch box depth of about 1.25 inches makes it ideal when wall depth is limited, especially behind wall-mounted TVs. The unit includes a UL-listed decorator-style receptacle, supporting a neat and integrated look where space is at a premium.
XGGYA Old Work Box For Switches
The XGGYA old work box is designed for retrofitting sockets in existing walls. It uses built-in fixing ears and a rotatable buckle to secure the box, reducing installation effort and avoiding visible holes. Its listed performance supports standard wiring projects while delivering a flush, clean appearance for retrofits in concrete-adjacent walls. The box dimensions and snap-on connections help prevent loosening after installation.
XIUTE 1-Gang PVC Old Work Box
The XIUTE 1-Gang PVC Old Work Box features a 14 cubic inch capacity, with a flange and adjustable installation label to ease installation in existing walls. Its non-conductive PVC construction reduces grounding requirements, while live hinges provide access to sheathed cables and additional cable support. This box is suitable for standard single-gang outlets and is optimized for simple retrofits in concrete-adjacent walls.
Legrand – Wiremold Starter Box
The Legrand Wiremold starter box provides an advanced conduit and raceway option when running internal wiring through concrete walls is impractical. This extra-deep white box supports heavy-duty conduit connections and aligns with on-wall raceways, delivering organized cable management for power and data needs. It’s particularly useful where walls prevent direct in-wall installations or where long raceways are required for clean visibility.
Togalonn Old Work Box 1 Gang
The Togalonn Old Work Box is UL-listed and offers a 14 cubic inch capacity in a sturdy PVC design. It emphasizes safety with fire-resistance properties for up to two hours, making it suitable for retrofits in spaces with potential heat sources. Adjustable mounting tabs ensure a flush, secure fit in existing drywall, which reduces movement and keeps outlets aligned over time.
Buying Guide
- Wall type compatibility: For concrete walls, prioritize in-wall or old-work boxes designed to anchor securely without crumbling the substrate. Look for boxes with robust mounting ears, adjustable tabs, and deeper profiles if needed.
- Cable management: Choose boxes with dedicated cable openings, brush grommets, and enough space to accommodate power, data, HDMI, and low-voltage runs. ENT entrances and built-in clamps help reduce cable clutter.
- Electrical requirements: Confirm box ratings (UL/ETL listed) and ensure compatibility with non-metallic sheathed cables, local electrical codes, and fire ratings for retrofit projects.
- Retrofit vs. new work: Old-work boxes simplify updates in existing walls, while new-work or recessed in-wall designs suit remodels where wall cavities are accessible from behind drywall.
- Depth and coverage: If installing behind a wall-mounted TV, a low-profile or recessed model minimizes protrusion and preserves a clean look. Measure wall thickness and drywall depth before selecting a size.
- Durability and safety: PVC and fire-rated plastics offer corrosion resistance and safer long-term performance in residential environments. Fire-rated options add extra protection in high-heat areas.
- Finish and aesthetics: For visible surfaces or raceways, consider white or gray-on-wall options that blend with existing trim, while ensuring the box’s dimensions don’t clash with décor or furniture layouts.
- Installation complexity: Some boxes require additional accessories (decorator receptacles, floor plates, or finish plates). Factor in the total kit when budgeting for a concrete-wall project.
