iMBAPrice IMBA-LVDR2-1 2-Gang Cut-in Combo Box
The IMBA-LVDR2-1 combines power and low-voltage routing in a single old-work box. The mounting bracket acts as its own template for precise cutouts, simplifying installation in existing walls that range from ¼” to 1-1/2″ thick. As screws are tightened, special wings flip up to secure the box in place. The low-voltage side includes 1/2″ and 3/4″ knockouts for cable raceways, while the power side ships with a pre-installed NM cable connector. Best for retrofit projects that need a neat, unified box rather than separate power and low-voltage boxes.
Who it’s best for: Homeowners upgrading a wall with both a traditional outlet and low-voltage devices in older walls. Builders seeking a single-template solution for precise hole cutting will appreciate the built-in mounting aid.
Why selected: Combines two functions in one box, reducing clutter and ensuring aligned openings with a single cutout process. The dual-domain design supports both power and low-voltage needs in one install.
Caution: Verify wall thickness and ensure offset accommodates both NM cables and low-voltage runs; the kit is optimized for standard retrofit scenarios.
Arlington LVD2 2-Gang Combo Box
Arlington’s LVD2 is a ready-to-install two-gang combo for power and low voltage. It is designed for new construction with nails already parked in place, which can speed up installation when framing is complete. The box accommodates both electrical outlets and low-voltage devices in a single unit, helping to keep wall penetrations minimal and aligned.
Who it’s best for: Builders and electricians working on new construction who want fast, accurate mounting without pre-assembly on site.
Why selected: Simple, efficient installation sequence for new builds, ensuring a clean, finished look with minimal wall modification.
Caution: Primarily marketed for new construction; remodel-friendly options may require compatible mounting hardware or extensions.
Southwire MSB1G One Gang Box With Depth Adjustable
The Southwire MSB1G provides depth-adjustable capabilities in a two-gang context with a focus on flexible mounting. Its design supports horizontal or vertical installation and accommodates deeper cable runs, making it a durable choice for spaces with tighter or more complex wiring pathways.
Who it’s best for: Projects requiring adaptive depth and versatile orientation, especially in retrofit situations where wall cavities vary.
Why selected: The depth-adjustable feature helps avoid overcrowding behind outlets and switches, reducing the risk of binding wires during installation.
Caution: Confirm the unit’s depth range matches the wall cavity and the expected cable count for your specific layout.
SmarToggle Two Gang Retrofit Box
The SmarToggle Two Gang Retrofit Box is designed for stud or no-stud installations, ideal for remodels and smart home upgrades. It uses snap-in 1-1/2″ toggles that lock securely for flush mounting, and provides seven wiring ports plus a 3/4″ knockout for conduit or cable routing.
Who it’s best for: Homeowners upgrading to smart devices or contractors performing remodels where stud access is limited or variable.
Why selected: Its dual-mount capability and sizable wiring ports make it a practical choice for multi-device configurations in limited spaces.
Caution: The complexity of wiring in retrofit scenarios may require careful planning to avoid overcrowding within the box.
MAKERELE 2 Gang Old Work Electrical Box
MAKERELE offers a 2-gang remodel box with 26 cubic inches of capacity and a 4″ depth, including a built-in wire clamp and fixing screws. It carries ETL certification and a 2-hour fire rating, delivering enhanced safety for remodel projects with significant wiring work.
Who it’s best for: Remodelers prioritizing safety credentials and adequate internal space for multiple devices and wires.
Why selected: The combination of built-in features (clamp, screws) and fire-rating contributes to steady, compliant installations in busy wall spaces.
Caution: Ensure the box depth aligns with wall thickness and stud spacing to avoid contact with exterior surfaces or other installed components.
Buying Guide
Key considerations when choosing a 2-gang dual voltage box:
- Wall type and installation: Old work vs. new construction determines whether a template, nails, or studs are required.
- Depth and capacity: Check cubic inches and depth to ensure enough space for multiple devices and wiring runs.
- Voltage and device compatibility: Confirm the box supports both power outlets and low-voltage devices if you plan a combined setup.
- Mounting method: Consider whether the box must be stud-friendly, retrofit-friendly, or adjustable for depth.
- Safety certifications: ETL or other certifications indicate compliance with safety standards, especially in remodels.
- Installation ease: Look for features like built-in clamps, pre-installed connectors, and self-template mounting.
