Middle Atlantic Floor BOX Dupl REC Comm - 863DPCOMAL

Middle Atlantic 863DPCOMAL Dual-Service Commercial Floor Box

Overview

The Middle Atlantic 863DPCOMAL is a dual-receptacle commercial floor box designed for structured installations where surface raceway or overhead drops aren't an option. At 5.75 in × 5.75 in × 4 in deep, it fits into a compact floor cutout while providing enough internal volume to land and dress two service connections cleanly — critical in AV equipment rooms, conference centers, open-plan offices, and any hardened commercial space where cable management has to be flush and professional.

Middle Atlantic's floor box line targets integrators who need Middle Atlantic infrastructure products that install once and stay put. The 863DPCOMAL is the commercial-grade dual-service variant in this family — built for the daily wear of foot traffic and repeated connection cycles that lighter-duty boxes can't sustain.

Key Features

• Dual-Service Configuration: Two receptacle positions in a single box reduce the number of floor penetrations required in a space. Fewer cutouts means a cleaner floor plane and less coordination with flooring contractors — relevant on retrofit jobs where minimizing disruption is as important as the final install.
• 5.75 in × 5.75 in Footprint: The square footprint fits standard commercial floor box rough-in cutouts. At under 6 inches on each side, it can be positioned in tighter tile grids or near furniture without conflicting with adjacent flooring elements. Confirm your subfloor depth accommodates the 4 in body before specifying on thin-slab concrete pours.
• 4 in Depth: The 4 in (10.2 cm) body depth provides working room for conductor terminations and service loop without forcing a sharp bend radius on heavier cable. On power distribution runs with 12 AWG or 10 AWG conductors, that slack matters for long-term connection integrity.
• Commercial-Grade Construction: Specified as commercial, not residential — the box is built to handle the mechanical stress of commercial floor environments including cleaning equipment, chair casters, and repeated lid open/close cycles that residential-spec products aren't rated for.
• Compact Square Profile: Matching width and depth (5.75 in on both axes) simplify rough-in layout calculations and template alignment, reducing layout errors during installation in grid-flooring systems.
• Non-TAA: The 863DPCOMAL is not TAA compliant. If your project has a federal or GSA procurement requirement for Trade Agreements Act compliance, this unit is not the correct specification — verify your procurement requirements before ordering.

Integration & Compatibility

The 863DPCOMAL is a floor infrastructure accessory intended for permanent installation in commercial environments. Integration considerations center on rough-in compatibility: confirm the subfloor construction (concrete slab, raised access floor, wood subfloor) supports the required cutout dimensions and that the 4 in body depth clears any conduit or structural elements beneath the floor plane.

For AV and security integration projects, floor boxes like the 863DPCOMAL are typically specified alongside cable management systems and rack infrastructure. Coordinate with the electrical contractor on conduit entry points — the box must be positioned before finish flooring is installed, and relocating after the fact is a significant cost. In raised-access floor environments, verify that the floor tile grid and tile size are compatible with the box's 5.75 in footprint before finalizing layout.

This unit is designed for the commercial segment of Middle Atlantic's floor box series. If your project requires data or AV ports integrated into the same floor box assembly alongside power, confirm whether a multi-service variant with data inserts is the better specification for your scope.

Frequently Asked Questions

Q: What are the dimensions of the 863DPCOMAL?

A: The 863DPCOMAL measures 5.75 in wide × 5.75 in deep × 4 in tall (14.6 cm × 14.6 cm × 10.2 cm).

Q: Is the 863DPCOMAL TAA compliant?

A: No. The 863DPCOMAL is not TAA compliant. Federal and GSA procurement projects with TAA requirements should specify a different unit.

Q: What type of floor construction is the 863DPCOMAL designed for?

A: The 863DPCOMAL is a commercial floor box suitable for concrete slab, wood subfloor, and raised-access floor environments, subject to confirming the 4 in body depth clears sub-floor obstructions and that the rough-in cutout matches the 5.75 in × 5.75 in footprint.

Q: How many service positions does the 863DPCOMAL provide?

A: The 863DPCOMAL is a dual-service (duplex receptacle) floor box, providing two service positions in a single floor cutout.

Q: Can the 863DPCOMAL be used in a raised-access floor system?

A: Yes, provided the raised-access floor tile grid accommodates the 5.75 in × 5.75 in cutout footprint and the tile thickness plus plenum depth are sufficient for the 4 in body. Verify tile compatibility with your floor system supplier before specifying.

James Everett

The 863DPCOMAL is a product I get asked about most often on AV and security integration projects where the architect has specified a clean floor plane — no surface raceways, no visible cable drops. The 5.75 in square footprint is the key spec here: it fits into standard commercial floor box rough-in templates without requiring a custom cutout, which keeps your coordination with the flooring sub simple and your schedule intact.

Technical Highlights:

• 5.75 in × 5.75 in footprint: Matches standard commercial rough-in dimensions, reducing layout coordination time and the risk of a mis-sized cutout that requires remediation before finish flooring goes down.
• 4 in body depth: Provides adequate termination room for commercial conductors without forcing tight bend radii — relevant when you're pulling 12 AWG or heavier from conduit stubs beneath the slab.
• Dual-service design: Two receptacle positions from one floor penetration keeps the floor grid cleaner and reduces the number of conduit stubs required from the electrical contractor — a real cost lever on larger open-plan deployments.

Deployment Considerations:

• Measure subfloor depth before specifying: the 4 in body must clear any conduit, rebar, or structural elements below the cutout. On thin-slab pours or shallow raised-access systems, this is a common fit issue that surfaces late if not checked early.
• The 863DPCOMAL is not TAA compliant — flag this immediately on any federal, state, or GSA-funded project. Substituting after rough-in is an expensive change order.

This unit fits best in commercial AV integration and enterprise security infrastructure projects — conference centers, open-plan offices, and equipment rooms where a flush, professional floor finish is part of the design intent and the dual-service footprint keeps penetrations to a minimum.
