Middle Atlantic Recessed Alum Cover - 828COMTCAL

Middle Atlantic 828COMTCAL Recessed Aluminum Communications Cover Plate

Overview

The Middle Atlantic 828COMTCAL is a recessed aluminum communications cover plate designed for use with OmniBox rectangular concrete floor box installations. At 3.25 inches wide, 2.75 inches high, and 4.25 inches deep, it provides a flush, professional finish for in-floor connectivity points in commercial environments — conference rooms, trading floors, open office deployments, or AV integration projects where surface-mount cable management is not an option. If you're spec'ing floor boxes for a Middle Atlantic infrastructure build or closing out a concrete floor communications rough-in, the 828COMTCAL is the cover plate that completes the assembly.

The aluminum construction gives it durability appropriate for high-traffic flooring environments without the visual bulk of heavier steel alternatives. The natural aluminum color finish integrates cleanly into commercial floor aesthetics and pairs with standard OmniBox rectangular floor box configurations. This is a purpose-built component — it's not a universal fit, so confirm your floor box model before ordering.

Key Features

• Recessed Profile (4.25 in depth): The 4.25-inch depth accommodates the recess needed for a fully flush installation in concrete floors — critical for meeting ADA and trip-hazard compliance in pedestrian traffic areas. A shallow cover that sits proud of the floor surface creates a liability; this depth spec is the one to verify against your slab pour before rough-in.
• Compact Footprint (3.25 in W × 2.75 in H): The 3.25 × 2.75-inch face keeps the floor penetration area minimal, which matters when you're coordinating with flooring contractors on tile or polished concrete layouts. Smaller cutouts preserve more structural integrity in thin-slab applications.
• Aluminum Construction: Aluminum offers a practical middle ground between weight and durability for floor box covers — lighter than steel for easier field handling during installation, resistant to the corrosion concerns that come with concrete moisture environments over time. The aluminum finish also avoids the paint-chip degradation common on powder-coated steel covers in high-foot-traffic zones.
• OmniBox Rectangular Platform Compatibility: This cover is engineered specifically for the OmniBox rectangular concrete floor box family from floor box and in-floor connectivity systems. That specificity means it fits correctly and seals as designed — no field modification, no gap between cover and box flange. Verify your existing floor box series matches before ordering.
• TAA Non-Compliant: The 828COMTCAL is confirmed TAA non-compliant. For federal government projects, GSA schedule work, or any contract requiring TAA compliance, this unit will not qualify. Identify TAA-compliant alternatives in the Middle Atlantic floor box line before specifying on government or federally funded projects.

Integration & Compatibility

The 828COMTCAL is designed as a component within the Middle Atlantic OmniBox rectangular concrete floor box ecosystem. It is not a standalone product — it completes an in-floor rough-in assembly. Integrators working on AV and communications infrastructure projects should confirm the specific OmniBox box model in use to ensure this cover plate matches the flange geometry and recess depth of the installed box. Consult the Middle Atlantic OmniBox product family documentation for full compatibility matrix and compatible inserts or modules that pair with this cover.

For projects requiring structured cabling and connectivity planning, pairing the correct cover plate with the right insert modules (communications, power, or combination) at the floor box stage avoids costly rework after concrete is poured and finished. The 828COMTCAL covers the communications configuration — if you need power or combination covers, confirm the appropriate variant from the same OmniBox family.

Frequently Asked Questions

Q: Is the Middle Atlantic 828COMTCAL TAA compliant?

A: No. The 828COMTCAL is confirmed TAA non-compliant. It should not be specified on federal government contracts, GSA schedule projects, or any project with a TAA compliance requirement.

Q: What are the dimensions of the 828COMTCAL cover plate?

A: The 828COMTCAL measures 3.25 inches wide, 2.75 inches high, and 4.25 inches deep (8.3 cm × 7 cm × 10.8 cm).

Q: What floor box system is the 828COMTCAL designed for?

A: The 828COMTCAL is designed for use with Middle Atlantic's OmniBox rectangular concrete floor box system. It is not a universal cover — verify your installed floor box model before ordering.

Q: What material is the 828COMTCAL made from?

A: The cover plate is aluminum, with a natural aluminum color finish. This makes it suitable for commercial flooring environments where corrosion resistance and a clean finish are required.

Q: Can the 828COMTCAL be used in outdoor concrete applications?

A: The evidence does not specify an environmental or ingress protection rating for the 828COMTCAL. For outdoor or wet-area floor box applications, confirm appropriate IP or NEMA ratings with Middle Atlantic before specifying this cover plate.

The 828COMTCAL comes up on jobs where the floor box rough-in is already committed and the finishing stage is where things go sideways. At 4.25 inches of recess depth with a 3.25 × 2.75-inch face, this aluminum cover plate is dimensionally specific to the OmniBox rectangular concrete floor box line — and that specificity is both its strength and the thing integrators most often overlook when ordering.

Technical Highlights:

• 4.25-inch recess depth: Matches the OmniBox rectangular box geometry for a flush, trip-safe finish — the depth spec is set to put the cover face level with the finished floor surface, not proud of it.
• 3.25 in × 2.75 in face dimensions: A compact footprint that minimizes the floor cutout area, which matters when coordinating with tile or polished concrete flooring contractors who need to know the exact opening size before finishing work begins.
• Aluminum construction: Resists the surface corrosion and paint degradation you see on powder-coated steel covers in high-foot-traffic or light-moisture concrete environments over a multi-year install lifespan.

Deployment Considerations:

• Confirm the installed OmniBox floor box model matches this cover's flange spec before ordering — the OmniBox line includes multiple configurations and this plate is not cross-compatible with all of them.
• TAA non-compliant: flag this early on any government, municipal, or federally funded project. Substituting a TAA-compliant cover after concrete is poured and finished is an expensive problem.

The 828COMTCAL is the right finish component for commercial AV and communications infrastructure builds using the Middle Atlantic OmniBox rectangular concrete floor box system — conference centers, higher-ed lecture halls, or corporate trading floors where in-floor connectivity needs a clean, durable, professional close-out.
