It supports charging laptops, smartphones, cameras, audio devices, game consoles, lamps, and shavers simultaneously. Its compact dimensions (about 3.35 by 1.37 by 1.5 inches) make it ideal for narrow spaces behind furniture or in tight corners, reducing visible cords and clutter. The design accommodates three bulky plugs at once without them blocking each other, maximizing use of limited wall space.
LENCENT 2 to 3 Prong Outlet Adapter (2 Pack)

This adapter set is designed for older or non-grounded outlets, converting a 2-prong setup into a 3-prong outlet to support modern devices. It creates a six-outlet power station and is suitable for high-demand appliances such as TVs, refrigerators, coffee makers, microwaves, and toasters. The side-by-side configuration ensures access behind furniture or TVs without blocking other outlets, with generous spacing to minimize plug crowding.
ARLINGTON FLBC4580 Round Floor Box

Available in brass or nickel finishes, it includes a 15-amp Decora-style power outlet. It offers an economical, clean installation path for floor power and data access in both new builds and renovations, with a focus on durability in concrete settings.
Sleek Socket Ultra-Thin Outlet Concealer

This patented, ultra-thin outlet concealer kit hides outlets and cords, providing a flat extension cord with six outlets and surge protection. It’s ideal for home offices, entertainment spaces, and behind TVs. The design emphasizes aesthetics by blending with walls while offering practical power access. Installation involves attaching to the duplex receptacle without tools, delivering a quick, tool-free setup for a clutter-free look.
SELECT Lighting Floor Box With Flip Lid

The SELECT Lighting SLFB-TR20-NI floor box combines a 20A receptacle with a tamper-resistant design and a nickel-plated bronze cover. The flip-lid mechanism keeps outlets protected when not in use while maintaining easy access when power is needed. This solution suits kitchens, countertops, and floors in both residential and commercial spaces, balancing safety with accessible power in elevated or high-traffic areas.
Buying Guide
Key purchase considerations help ensure you choose floor or in-floor sockets that fit your space and safety needs.
- Installation environment: Determine whether you’re wiring into new concrete pours or upgrading an existing slab. Some products are designed for retrofit in existing floor boxes, while others target above-floor or surface-mounted setups.
- Power requirements: Match amperage and voltage to anticipated devices. For kitchens and workshops, look for 15A or 20A outlets and consider surge protection where high-powered equipment is used.
- Safety features: Tamper-resistant outlets, weatherproof sealing, and child-safety designs help prevent accidents. Consider covers or lids that close flush when not in use to minimize tripping hazards.
- Aesthetics and space: Recessed, low-profile, or ultra-thin designs reduce visual impact and keep floors smoother for foot traffic or furniture movement.
- Outlets vs adapters: Outlets integrated into the floor box provide clean, permanent access, while adapters can expand existing outlets but may affect spacing and grounding requirements.
- Durability and materials: Choose corrosion-resistant finishes (brass, nickel) and rugged housings if the floor area experiences moisture, humidity, or heavy foot traffic.
- Compatibility: Check that the product accommodates your plug types (2-prong, 3-prong, or more complex configurations) and aligns with your floor type (concrete, tile, or wood overlays).
- Maintenance: Look for products with simple access for repairs or replacements and consider ease of cleaning around recessed components to avoid debris buildup.
