Middle Atlantic Sngl Comm/power Alum 3/4 - 830CKTCAL-3/4

Middle Atlantic 830CKTCAL-3/4 Single Comm/Power Aluminum Cover Plate

The Middle Atlantic 830CKTCAL-3/4 (often searched as 830CKTCAL 3/4) is a single-gang aluminum duplex cover plate designed for the OmniBox rectangular concrete floor box series. At 3.25" wide, 0.5" tall, and 4.25" deep, it fits flush into the floor box opening and provides a finished, low-profile termination point for combined communications and power pass-through — the kind of clean infrastructure detail that matters in open-plan offices, conference rooms, and AV/security integration environments where floor boxes handle the last-mile connection.

Key Features

• Aluminum construction (3.25" W × 4.25" D × 0.5" H): aluminum resists corrosion and holds up under foot traffic better than plastic covers — relevant anywhere the floor box sits in a pedestrian path or under rolling equipment.
• Single comm/power configuration: one plate handles both a data/communications port and a power outlet in the same footprint, reducing the number of floor box inserts needed and keeping cable runs consolidated at the source.
• Low-profile 0.5" height: at half an inch tall when seated, the cover sits nearly flush with finished concrete or tile surfaces — no trip hazard, no raised lip that catches cart wheels or chair casters.
• Rectangular OmniBox compatibility: designed specifically for Middle Atlantic's rectangular OmniBox concrete floor box family, ensuring the plate seats squarely and the opening dimensions align without field modification.

Integration & Compatibility

The 830CKTCAL-3/4 is engineered for the Middle Atlantic OmniBox rectangular concrete floor box platform. Verify your floor box model matches the rectangular OmniBox spec before ordering — Middle Atlantic also produces round and square variants with different cover dimensions. For full Middle Atlantic floor box and infrastructure solutions, including compatible inserts and cover accessories within the cable management and floor box category, confirm the base box dimensions match the 3.25" × 4.25" cover footprint.

Frequently Asked Questions

Q: What floor box is the 830CKTCAL-3/4 designed for?

A: The 830CKTCAL-3/4 is designed for Middle Atlantic's OmniBox rectangular concrete floor box series. It is not a universal cover — verify your base box is the rectangular OmniBox variant before ordering.

Q: What are the dimensions of the 830CKTCAL-3/4 cover plate?

A: Width 3.25 in (8.3 cm), height 0.5 in (1.3 cm), depth 4.25 in (10.8 cm).

Q: Is the 830CKTCAL-3/4 made of aluminum or plastic?

A: It is aluminum construction, as indicated in the product name and the Legrand AV product listing for this SKU.

Q: Can the 830CKTCAL-3/4 be used in a round floor box?

A: No. The 830CKTCAL-3/4 is a rectangular cover plate matched to the rectangular OmniBox. Round floor box variants use different covers with different opening geometry.

When I spec floor infrastructure for AV and security integration projects, the cover plate is often the last thing on the BOM and the first thing that causes a field callback — wrong footprint, wrong material, wrong gang count. The 830CKTCAL-3/4 eliminates that call for rectangular OmniBox installs: at 3.25" wide and 4.25" deep with a 0.5" profile, it drops in flush and handles both comm and power in a single aluminum plate that won't flex or crack under a chair base.

Technical Highlights:

• 3.25" × 4.25" footprint: matches the rectangular OmniBox opening exactly — no shimming, no field cutting, no gap at the perimeter edge that collects debris in a concrete floor install.
• 0.5" installed height: low enough to clear standard ADA rolling clearance requirements in most commercial buildouts and low enough that AV cables exiting the box don't create a visible hump under a boardroom table skirt.
• Aluminum body: aluminum over the plastic alternatives holds torque on the insert screws over years of access cycles — relevant in a conference room floor box that gets opened every week for laptop hookups.

Deployment Considerations:

• Confirm the base floor box is specifically the rectangular OmniBox variant before ordering — Middle Atlantic's round and square box families use different cover dimensions and the 830CKTCAL-3/4 will not seat correctly on them.
• Evidence covers physical dimensions only; insert/module compatibility (keystone, Decora, duplex receptacle type) should be verified against the full OmniBox configuration guide from Legrand AV before finalizing the BOM.

The 830CKTCAL-3/4 is the right spec for conference rooms, training centers, and open-plan AV integration environments where a rectangular OmniBox is already in the concrete pour and the finished install needs a durable, low-profile comm/power surface that won't stand out on a polished floor.
