ARLINGTON FSC405R Shallow Sconce Box
The ARLINGTON FSC405R is a shallow flexible sconce box designed for compact installations. It measures 4 inches in width and 0.5 inches in depth, offering a cubic capacity of 5 cubic inches. The box comes in black and is suitable for surface-mounted or recessed applications where a slim profile is required. Its shallow depth helps minimize wall intrusion while providing a defined junction space for wiring connections and light fixtures in low-clearance areas.
Key features include a compact footprint and a basic, non-metallic construction. This makes it a practical choice for sconce-type fixtures or small lighting retrofits where depth is at a premium. Installation is straightforward for standard old-work situations, though cabinets or beams may affect fit in already tight walls. Ideal for decorative lighting needs in hallways or bedrooms where a slim electrical box is preferred.
AIRTAK Round 18 Cu.in. Old Work Box
The AIRTAK round old-work box provides 18 cubic inches of interior space with a 4.25-inch diameter and 2.75-inch depth. It features flanges and adjustable clips, plus jacketed cable jacks, designed to simplify wall and ceiling installations. Grounding is supported, and the thermoplastic construction is resistant to rust and impact while remaining non-conductive. The package includes a single box for straightforward retrofits, making it a solid choice for upgrading old wiring inplace.
With an ETL-listed, fire-rated context, this box aims to meet safety standards in residential projects where spaces are constrained. Installation benefits from a robust mounting system and a spacious interior to accommodate multiple conductors, though users should verify fit in their wall cavity before proceeding with wiring tasks.
Carlon B618R-UPC 4-1/4″ Round Old Work Box
The Carlion B618R-UPC is a non-metallic old-work round box with a 4-1/4 inch diameter and 18 cubic inches of capacity. Made from phenolic material, it’s designed for durability and easy installation in retrofit projects. Its round shape fits standard ceiling or wall mounting scenarios, and the non-metallic construction reduces surface conduction and simplifies wiring in typical American homes. The B618R-UPC is suitable for light fixtures, switches, and other low-to-mid wattage electrical devices where space is limited.
Consider compatibility with existing electrical boxes and ensure the surrounding drywall thickness aligns with the box depth to avoid over-compression of cables. This option balances durability, ease of installation, and capacity for moderate wiring needs in old-work renovations.
XIUTE 1 Gang PVC Round Ceiling Box
The XIUTE 1 Gang round old-work box is a 4.25-inch diameter PVC unit with an 18 cubic inch capacity. It includes a grounding strap and screws, and is ETL listed, offering reliable compliance for residential wiring installations. The product is designed for easy, one-person installation with a live hinge and adjustable labels, making it practical for retrofits involving ceiling or wall-mounted fixtures that require a simple, sturdy box with adequate space for conductors. Its blue color helps with visibility in some installations.
Material choice (PVC) provides corrosion resistance and dielectric properties that suit many modern wiring environments. While installation is straightforward, verify that the box will fit behind drywall and consider future access in case of updates or maintenance needs.
XGGYA 4” Old Work Round Box
The XGGYA 4” old-work round electrical box is a 4-inch diameter, 18 cubic inch capacity PVC unit, ETL listed for reliability in old-work installations. The box is designed for single-gang applications and is suitable for close connections in ceilings or walls where adding a fixture or junction point is necessary. Its blue color marks its PVC construction, which contributes to durability and ease of handling during retrofits. The package promises straightforward one-person installation with a focus on keeping conduit and cable paths organized in tight spaces.
Consider the project’s required conductor count and ensure that the box depth aligns with the surrounding wall thickness. PVC materials provide safe insulation and resistance to environmental factors common in interior retrofit work.
Buying Guide: Key Purchase Considerations
Depth and capacity: Shallow boxes should fit the available cavity without causing drywall bowing or fixture misalignment. Check both the diameter and the internal cubic inch capacity to ensure enough room for conductors, connectors, and any connectors or clamps required by local code.
Material and durability: PVC and phenolic boxes are common for old-work installations due to lightweight durability and ease of mounting. Plastic boxes typically resist corrosion and are non-conductive, while phenolic or other composites may offer higher rigidity in some scenarios.
Installation features: Look for flanges, adjustable clips, grounding provisions, and built-in mounting wings or tabs. These features simplify retrofits and help secure the box against movement, particularly in ceilings where vibrations or thermal changes occur.
Fire safety and codes: Many boxes are ETL listed or rated for fire-rated walls (2-hour walls). Confirm local code compliance to ensure safe integration with switches, outlets, or lighting fixtures.
Ease of use: Consider live hinges, ground connections, and screw placements that facilitate one-person installation. A clearly labeled box can save time and reduce risk during retrofit projects.
Suitability for fixtures: If you plan to install lighting fixtures or ceiling fans, select a box with enough space and appropriate support to handle anticipated loads. Ensure the mounting method matches fixture requirements for safe operation.
