Floor Boxes

Floor boxes provide floor-level locations for power, communication, and cable connections in commercial electrical installations. This category includes floor boxes and compatible components for raised, wood, tile, open-space, and poke-through floor applications, helping electrical installers and facility teams configure accessible service points and organize routed cables.

Helpful Buying Guide

Choose floor box components for the installation you are building

Floor-level electrical and communication installations can require more than a box alone. Compare the floor construction, system format, gang size, device connection needs, cable-access features, and compatibility details before selecting a floor box, plate, flange, housing, or retrofit component.

Use Cases

Bring connections to floor level

Use floor boxes and related components to create accessible locations for power, communication, audio/video devices, receptacles, and cable routing through the floor.

How to Choose

Match the system and opening

Confirm whether the project uses a compatible floor box series, poke-through system, cellular raceway system, 3/4-inch conduit, or an 8-inch core-hole system. Also compare gang configuration and listed dimensions.

Applications

Consider the floor environment

Available options support raised and wood floors, tile-floor applications, open-space installations, and qualifying air-handling spaces. Some components also support floors rated up to 2 hours.

Additional Information

Plan for access and protection

Some components include flip-top coverage, recessed self-closing handles, auto-closing egress doors, lock-open positions, scrub water protection, or the listed protection feature for installed assemblies.

Planning Guide

Plan the right fit before choosing

Start with the floor box format

Choose a box or component that fits the installation approach

Floor box options in this category include a two-gang tile flange box and a white floor box with a communication flange and slide holder for raised or wood floors. Poke-through components include conduit housings, activate plates, flanges, slide holder assemblies, retrofit kits, and device plates.

  • Choose two-gang capacity where a two-gang floor box format is required.
  • For raised or wood floors, consider a floor box with a communication flange, slide holder, and flip-top cover plate.
  • For tile applications, select a tile flange configuration.
  • For poke-through work, verify the required housing, activate plate, flange, device plate, or retrofit component.
Configure services and cable access

Match plates and access features to the connections being installed

Device and communication plates help configure compatible floor boxes for receptacles, decorator-style devices, AAP devices, and audio/video devices. Cable-access components with egress doors can close around installed cables and lock open during cable positioning.

  • Select a single-receptacle device plate when a defined 1.6-inch receptacle opening is needed.
  • Choose a six-port communication plate for multiple communication-device connection positions.
  • Consider a device plate with independent compartments when organized power and communication routing is needed.
  • Use auto-closing egress doors when routing cables through a poke-through opening.
Confirm compatibility and project conditions

Review dimensions, ratings, and installation details before purchase

Several components are made for specific compatible floor box series or systems. Listed sizes, conduit compatibility, core-hole requirements, cover compatibility, and floor conditions help determine the appropriate selection. Certain poke-through assemblies and retrofit kits are suitable for qualifying air-handling spaces in accordance with NEC Section 300.22(C) and support floors rated up to 2 hours.

  • Compare listed dimensions with the planned floor box or project opening.
  • Verify 3/4-inch conduit compatibility where applicable.
  • Match an 8-inch core-hole system when selecting the applicable poke-through AAP plate.
  • Check whether existing covers, round covers, or mounting brackets are compatible with the selected configuration.
