Hubbell CFB2G25RCRE Recessed 2-Gang Concrete Floorbox with Round Cover

Overview

The Hubbell CFB2G25RCRE is a recessed 2-gang concrete floorbox built for slab-poured commercial installations where power and data devices need to sit flush with a finished floor. It's sized for a 2.5-inch depth of pour and finished in a corrosion-resistant metallic/green epoxy coating over galvanized stamped steel — the combination you want when the box goes into a slab before flooring is finalized and stays there for the life of the building. With a round cover plate and screw-mount device mounting plates, CFB2G25RCRE is set up to accept standard device plates for outlets, data jacks, or a mix of both in a single recessed footprint.

Key Features

\n
• 2.5in Minimum Depth of Pour: matches standard raised-access and slab-on-grade pour depths on commercial floors, so the box sits flush without requiring a non-standard slab thickness — check this against your architect's floor plan before ordering.
\n
• 2-Gang Configuration: two device positions in one recessed box, enough room to combine a duplex power outlet with a data/voice jack without running a second floorbox for the same workstation.
\n
• 10 Knockouts: gives the electrician multiple conduit entry points to choose from depending on which direction the underground or in-slab conduit run approaches the box, cutting down on field modifications during rough-in.
\n
• Galvanized Stamped Steel Body: a stamped (not cast) steel construction that holds up under the concrete pour and the foot traffic load above it once the slab cures.
• Corrosion-Resistant Metallic/Green Epoxy Paint: the epoxy coating is the difference between a floorbox that lasts through decades of embedded slab moisture and one that starts rusting from the outside in — relevant because this box isn't accessible for touch-up once it's poured over.
\n
• Round Cover Plate: a round-style finish plate for the floor-level opening, matched to the 2-gang device layout underneath.
\n
• Screw Mount Device Mounting Plates: devices anchor to the box with mounting plates rather than snap-fit clips, giving a more secure hold for hardware that will see repeated plug-in/plug-out cycles at a floor-level workstation.
\n
• 16.27in x 7.32in x 3.25in Body Dimensions: confirms the box footprint and height before you cut the slab opening or set the pour form — get this wrong and you're coring concrete after the fact.
\n
• 9.9lb Product Weight: steel-bodied floorboxes carry real mass; factor this into how the box is staged and set in the form before concrete goes in, since it isn't held in place by adhesive alone.

Integration & Compatibility

CFB2G25RCRE is built around a 2-gang device layout, so it accepts standard 2-gang power and low-voltage device plates — a practical pairing point if you're also speccing IP cameras or access control readers that terminate at a floor-level workstation rather than a wall. For facilities running structured cabling to floor-mounted workstations, this floorbox sits alongside your broader network video recorder and switch closet planning — the floorbox handles the device termination point, not the head-end. If you're laying out a new build with multiple recessed boxes across an open floor plan, review a PoE planning guide before finalizing conduit runs, since power and data pathways both route through boxes like this one. For the broader family of Hubbell wiring devices and floor/wall boxes used on the same job, see the Hubbell product catalog. Buyers speccing floor-level device locations for camera controllers or workstation power in a larger surveillance build should also check mounting accessories for above-floor hardware that pairs with this box's device plates.

Frequently Asked Questions

Q: What depth of concrete pour does the CFB2G25RCRE require?

A: CFB2G25RCRE has a minimum depth of pour of 2.5 inches, matching its box height of 3.25 inches for a flush recessed installation.

Q: How many devices fit in the CFB2G25RCRE?

A: It's a 2-gang floorbox, accepting two device positions — commonly a power outlet paired with a data or voice jack.

Q: How many conduit knockouts does this floorbox have?

A: CFB2G25RCRE includes 10 knockouts for conduit entry from multiple directions.

Q: Is the CFB2G25RCRE corrosion resistant?

A: Yes. It's finished in a metallic/green epoxy paint over galvanized stamped steel construction for corrosion resistance in embedded slab applications.

Q: How are devices mounted inside the CFB2G25RCRE?

A: Devices attach using screw-mount device mounting plates rather than snap-in clips.

Q: What are the overall dimensions of the CFB2G25RCRE?

A: The box measures 16.27 inches by 7.32 inches with a height of 3.25 inches, and weighs 9.9 lbs.

When I spec a floorbox for a slab pour, the depth-of-pour number is the first thing I check against the architect's drawings, and CFB2G25RCRE's 2.5-inch minimum lines up with a lot of standard commercial slab designs. This is a 2-gang recessed box, so it's meant for locations where you're combining a power drop with a data or voice line at a single floor-level workstation.

\n

Technical Highlights:

\n

\n
• 2.5in Minimum Depth of Pour: aligns with common slab-on-grade thicknesses — confirm against your specific floor plan before the pour, since this isn't adjustable after concrete goes in.
\n
• 10 Knockouts: gives the electrician flexibility on conduit entry angle, which matters more than people expect when the in-slab conduit run doesn't approach the box dead-on.
\n
• Galvanized Stamped Steel with Epoxy Coating: the corrosion-resistant finish matters specifically because this box is inaccessible once poured — there's no repainting a floorbox embedded in concrete.
\n

\n

Deployment Considerations:

\n

\n
• At 9.9 lbs and 16.27in x 7.32in, this box needs to be staged and leveled in the form before the pour — it's not a lightweight fixture you set and forget.
\n
• The round cover and 2-gang layout are fixed — if the workstation needs more than two device positions, this isn't the box; look at a larger-gang model in the same Hubbell floorbox line.
\n

\n

This is the right call for a commercial open-office or conference room build where a single floor-level workstation needs both power and low-voltage device termination in one recessed, corrosion-resistant box rated for direct concrete embedment.
