Middle Atlantic Dup/gfi Alum Cover - 828DPGFITCAL

Middle Atlantic 828DPGFITCAL Aluminum Duplex GFI Floor Box Cover Plate

Overview

The Middle Atlantic 828DPGFITCAL is a rectangular aluminum cover plate engineered for concrete floor box installations requiring a duplex outlet and GFI receptacle cutout in a single, low-profile assembly. At just 0.25 inches tall above the floor surface, this cover sits flush enough to avoid a trip hazard in high-traffic commercial environments — a detail that matters on open office floors, boardrooms, AV staging areas, and security operations centers where cable management runs underfloor. The 828DPGFITCAL is part of Middle Atlantic's floor box and raceway line, a catalog built around infrastructure that stays out of the way and keeps installations looking finished.

This is not a universal fit cover — it is purpose-built for the rectangular concrete floor box series it was designed to cap. Before ordering, verify your floor box model and cutout pattern match the 828DPGFITCAL's 3.13 x 4.13-inch footprint. Pairing a cover to the wrong box wastes a service call.

Key Features

• Aluminum construction (3.13" W x 4.13" D): Aluminum resists corrosion and holds up to cleaning chemicals used on commercial hard floors — concrete, tile, and polished stone environments that would eventually pit or stain a powder-coated steel cover. The 3.13 x 4.13-inch profile fits the targeted rectangular floor box series without modification.
• 0.25-inch above-floor height: At a quarter-inch proud of the floor, the cover presents minimal trip risk in pedestrian-heavy spaces. ADA-accessible floor installations and open-plan commercial areas benefit from the lowest-profile cover that still accommodates standard duplex and GFI receptacles beneath it.
• Duplex + GFI configuration: Supporting both a standard duplex outlet and a ground fault interrupter receptacle in one cover plate means you can bring both standard and GFCI-protected power to a single floor point — useful in wet-rated or code-required zones where a GFI circuit is mandatory alongside utility power.
• Concrete floor box application: Designed specifically for concrete slab installations rather than raised-access or wood-subfloor boxes, the 828DPGFITCAL is the correct finishing component for core-drilled or cast-in-place conduit runs in commercial construction. Using an incompatible cover on a concrete box creates seal and stability problems — this part eliminates that risk when matched to the correct base.
• TAA status — not compliant: The 828DPGFITCAL is not TAA compliant. If your project falls under federal procurement rules (GSA schedules, government facilities, DoD installations) requiring TAA-compliant components throughout, select an alternate cover from Middle Atlantic's floor infrastructure line that carries TAA designation. For commercial, enterprise, and non-government deployments, TAA status is typically not a constraint.
• Aluminum finish: The natural aluminum color blends with commercial flooring hardware and standard electrical device finishes. It coordinates with the broader palette used in AV and security infrastructure closets without requiring paint or special finishing.

Integration and Compatibility

The 828DPGFITCAL is designed as a finishing cover for Middle Atlantic's rectangular concrete floor box series. Compatibility is mechanical — the cover must physically match the floor box base's bolt pattern, receptacle cutout spacing, and overall opening dimensions. If you are building out a structured power distribution and floor infrastructure system, verify the full Middle Atlantic floor box part number before adding this cover to a bill of materials. Mismatched covers result in gaps around receptacles, unstable lid action, and potential code issues at inspection.

For integrators specifying complete floor box assemblies for conference rooms, operations centers, or security command posts, the 828DPGFITCAL pairs with the appropriate Middle Atlantic floor box body and any standard-size duplex and GFI devices that fit within the 3.13 x 4.13-inch footprint. Coordinate with your electrical contractor on device body depth and box depth before finalizing the assembly. Consider also cable management accessories for routing low-voltage cabling alongside the power circuit through the same floor penetration.

Frequently Asked Questions

Q: What are the exact dimensions of the 828DPGFITCAL cover plate?

A: The 828DPGFITCAL measures 3.13 inches wide, 4.13 inches deep, and 0.25 inches in height above the floor surface.

Q: What material is the 828DPGFITCAL made from?

A: It is constructed from aluminum, which provides corrosion resistance suitable for commercial hard-floor environments.

Q: Is the 828DPGFITCAL TAA compliant?

A: No. The 828DPGFITCAL is not TAA compliant. Federal or government procurement projects with TAA requirements should verify an alternate Middle Atlantic part number that carries TAA designation.

Q: What type of floor box does the 828DPGFITCAL fit?

A: It is designed for Middle Atlantic's rectangular concrete floor box series. Confirm the matching floor box model number before ordering — this cover is not a universal fit across all floor box brands or styles.

Q: Can the 828DPGFITCAL be used in raised-floor or wood-subfloor applications?

A: The 828DPGFITCAL is specified for concrete floor box installations. Compatibility with raised-access or wood-subfloor box models should be verified against the specific floor box base part number before use.

Q: Does the 828DPGFITCAL support both duplex and GFI receptacles?

A: Yes. The cover plate is configured to accommodate both a standard duplex outlet and a GFI (ground fault interrupter) receptacle in a single floor box assembly.

Eden Phillips

The detail that gets overlooked on floor box assemblies is cover height, and the 828DPGFITCAL addresses it directly — at 0.25 inches above the finished floor, this aluminum cover sits low enough to avoid flagging during accessibility reviews while still clearing standard duplex and GFI device bodies below. I specify it on commercial AV and security command center builds where the floor box is in a pedestrian path and a taller cover would create a code or liability problem.

Technical Highlights:

• Aluminum construction: Holds up to floor-cleaning chemicals and foot traffic without the surface degradation you'd see on coated steel over a 5-10 year lifecycle in a high-use commercial space.
• 3.13" x 4.13" footprint: Sized precisely for the Middle Atlantic rectangular concrete floor box series — not a nominal fit that requires shimming or trimming at install.
• 0.25" above-floor profile: Keeps the assembly within ADA ramp-slope thresholds for floor obstructions and eliminates the visible lip that catches carts, dollies, and rolling chairs in open-plan spaces.

Deployment Considerations:

• Verify the floor box base part number before ordering — the 828DPGFITCAL is matched to Middle Atlantic's rectangular concrete floor box series specifically, and a bolt-pattern mismatch won't be apparent until you're on-site.
• TAA non-compliance is the one hard stop: any government facility, GSA-schedule project, or DoD installation with TAA requirements on every component needs a different cover part number from the Middle Atlantic line.

Best fit: conference rooms, security operations centers, and open-office AV infrastructure on concrete slab construction where a finished, low-profile power access point is part of the design spec rather than an afterthought.
