Middle Atlantic 4IN Unwired PT Assembly SN - 4ATCSN

Middle Atlantic 4ATCSN 4-Inch Unwired Poke-Through Floor Assembly, Satin Nickel

Overview

The Middle Atlantic 4ATCSN is a 4-inch unwired poke-through table and floor assembly designed for clean, professional cable routing in conference rooms, command centers, and integrated AV/IT environments. With a satin nickel surface cover and zero pre-installed outlets, the 4ATCSN ships as a blank-slate assembly — you provision it with the specific inserts your project requires rather than paying for capacity you won't use. For integrators managing mixed AV, data, and low-voltage runs in a single floor penetration, this approach keeps the bill of materials tight and the finished installation looking intentional.

Middle Atlantic is part of the Middle Atlantic product line, a Legrand AV brand with deep roots in rack infrastructure and AV integration. The 4ATCSN fits squarely in that lineage: infrastructure hardware built for commercial deployment, not consumer workarounds.

Key Features

• Unwired, Insert-Ready Design: The 4ATCSN ships with zero pre-installed outlets or modules — meaning you configure it for the exact mix of power, data, HDMI, USB, or low-voltage inserts your project calls for. No stripping out unwanted modules, no paying for duplex outlets you'll tape over. For integrators running multiple job types, a single unwired SKU covers far more scenarios than a pre-wired variant.
• Surface Cover Style: The surface-mount cover sits flush against the floor or table surface rather than recessing below grade, simplifying retrofit installations where core drilling depth is constrained. You don't need to hit a precise depth to get a finished look.
• Satin Nickel Finish: The satin nickel color coordinates with standard brushed-metal AV and conferencing hardware — appropriate for boardrooms, huddle spaces, and executive environments where a chrome or black finish would stand out. Finish consistency across a multi-unit installation matters more than it sounds when everything else on the table is also satin nickel.
• TAA Compliant: The 4ATCSN is TAA (Trade Agreements Act) compliant, which matters for federal government projects, GSA schedule procurement, and any public-sector bid that requires domestic or designated-country manufacturing. If your customer is a federal agency, state government, or defense contractor, TAA compliance is often a hard gate — this unit passes it.
• 4-Inch Form Factor: The 4-inch diameter fits standard 4-inch floor core cuts common in commercial construction. Coordinating with a building's existing floor-box knockout pattern is straightforward — no custom core work required in most cases.
• Zero Duplex Outlets: With no duplex outlets pre-installed, there is no electrical load to account for during rough-in. Low-voltage-only configurations (data, HDMI, USB-C) stay out of the electrician's scope entirely, which can simplify permitting on some jobs.

Integration & Compatibility

The 4ATCSN is part of Middle Atlantic's 4AT Evolution poke-through device family. As an unwired assembly, it accepts compatible Middle Atlantic insert modules for power, data, and AV signal — select inserts separately based on the specific port mix your installation requires. Confirm insert compatibility with the 4AT Evolution series before ordering modules.

For broader cable management and structured wiring planning, the 4ATCSN pairs with rack infrastructure, cable trays, and low-voltage pathway components commonly specified in the same bill of materials. If your project also involves surveillance or access control head-end equipment, Middle Atlantic rack and power distribution products integrate directly into that equipment chain.

TAA compliance makes this unit appropriate for government and public-sector security infrastructure projects where country-of-origin documentation is required at bid time.

Frequently Asked Questions

Q: Is the Middle Atlantic 4ATCSN TAA compliant?

A: Yes. The 4ATCSN is TAA (Trade Agreements Act) compliant, making it eligible for federal government, GSA schedule, and other public-sector procurements that require TAA-designated country of origin.

Q: Does the 4ATCSN come with outlets or modules pre-installed?

A: No. The 4ATCSN ships as an unwired assembly with zero duplex outlets and no pre-installed modules. You select and add compatible Middle Atlantic 4AT Evolution inserts separately to match your specific AV, data, or power requirements.

Q: What finish is the 4ATCSN cover?

A: The cover is satin nickel, a brushed-metal finish that coordinates with standard commercial AV and conferencing hardware.

Q: What is the cover style on the 4ATCSN — surface or recessed?

A: Surface. The cover sits at floor or table surface level, which simplifies retrofit installations where drilling to a precise recessed depth is not practical.

Q: What are the shipping dimensions for the 4ATCSN?

A: The 4ATCSN ships in a box measuring 21 inches x 8.25 inches x 8.25 inches (533.4 x 209.6 x 209.6 mm).

Q: Is the 4ATCSN part of a larger Middle Atlantic poke-through family?

A: Yes. The 4ATCSN is part of the Middle Atlantic 4AT Evolution poke-through device series, which includes wired and unwired variants as well as a range of compatible insert modules for power, data, and AV signal.

Jerry Tildsen

The Middle Atlantic 4ATCSN comes up regularly on government and corporate campus jobs specifically because of that TAA compliance designation — once a federal end-user or GSA contracting officer is in the picture, non-TAA floor boxes get pulled from the submittal regardless of price. The unwired format is the right call on mixed-use tables where the AV consultant hasn't finalized the insert layout when rough-in happens; you core the floor, drop the assembly, and make module decisions later without touching the slab again.

Technical Highlights:

• TAA Compliant: Passes the Trade Agreements Act country-of-origin requirement — a hard gate on federal, state, and defense contractor bids that eliminates many competing floor-box options at submittal review.
• Zero Pre-Installed Outlets (Unwired): No duplex outlets means no electrical rough-in coordination for low-voltage-only configurations — data and AV runs stay out of the licensed electrician's scope on jobs where that separation saves schedule time.
• Surface Cover Style: Surface-mount fit avoids the depth-tolerance problem that trips up recessed covers in retrofit cores — particularly relevant in older concrete slabs where you're not guaranteed a clean, consistent depth across multiple penetrations.

Deployment Considerations:

• The 4ATCSN ships as a bare assembly — budget line items for compatible 4AT Evolution insert modules separately; the unit itself contributes zero port capacity until inserts are specified and ordered.
• Satin nickel is a fixed finish on this SKU; if your project specifies black or white table hardware uniformly, verify finish compatibility before committing — Middle Atlantic offers other cover finish options within the 4AT Evolution family.

The 4ATCSN is the right specification for TAA-sensitive government conference rooms and executive boardrooms where the integrator needs finish-neutral, insert-configurable floor access and can't afford a non-compliant component to kill the submittal.
