Middle Atlantic 4IN Cover Assembly Surface SB - 4CTCSB

Middle Atlantic 4CTCSB Surface Cover Assembly — Satin Brass

Overview

The Middle Atlantic 4CTCSB is a surface-style cover assembly designed for the 4AT Evolution poke-through device family. If you're finishing a conference room, training space, or collaboration area where floor boxes or in-floor poke-throughs are part of the infrastructure, the cover is what your end users actually see and interact with — and the satin brass finish on the 4CTCSB is built to complement upscale commercial interiors where chrome or black would read as too industrial. This is the component that closes out the installation cleanly and presents a polished, professional surface at the floor level.

The 4CTCSB ships with surface cover style geometry, meaning it sits at or just above the finished floor plane rather than recessing flush. For installations where the floor composition or tile thickness makes a fully flush fit impractical, the surface mount approach gives you a reliable seal without precision substrate work — a real advantage when retrofitting existing floors rather than pouring new concrete around a conduit stub.

Key Features

• Satin Brass Finish: The warm metallic tone integrates naturally into executive boardrooms, hospitality venues, and high-end office environments. Where a standard black or chrome cover would draw attention, satin brass reads as intentional detail work — appropriate when the AV or network infrastructure is meant to be invisible to the room occupant.
• Surface Cover Style: Designed for above-floor-plane installation, this cover style accommodates varying substrate thicknesses without requiring precision core depth matching. Useful in retrofit scenarios on existing tile, hardwood, or raised-access flooring where a fully recessed fit is not achievable.
• Standard Receptacle Type: The standard receptacle configuration means you're working with a common outlet geometry — no specialty inserts, no proprietary tooling required. Field techs familiar with the 4AT family can terminate and dress this cover without a learning curve.
• TAA Compliant: The 4CTCSB is TAA (Trade Agreements Act) compliant, which matters directly for government, federal contractor, GSA schedule, and DOD-adjacent deployments where country-of-origin requirements govern procurement. If your project has TAA language in the spec, this cover clears that gate — verify your full bill of materials, but the cover itself won't be the item that fails compliance review.
• Compact Shipping Profile: The 4CTCSB ships in a 5.63" × 5.63" × 5.5" (143.1 × 143.1 × 139.7 mm) package — easy to stage in quantity on larger flooring projects without consuming significant storage space at the job site.

Integration & Compatibility

The 4CTCSB is part of Middle Atlantic's broader Middle Atlantic poke-through and cable management line, specifically matched to the 4AT Surface Style Evolution poke-through device. When specifying floor boxes and poke-through devices for commercial AV or structured cabling projects, confirm the cover model matches the base device family — surface covers are not interchangeable with flush-mount variants across all configurations. For projects requiring AV infrastructure accessories beyond the cover assembly, Middle Atlantic's portfolio extends to rack systems, power, and cable management. If your deployment is TAA-sensitive, cross-reference this 4CTCSB against your full TAA-compliant products list to confirm every component in the poke-through assembly meets the same standard.

Frequently Asked Questions

Q: Is the 4CTCSB TAA compliant?

A: Yes. The 4CTCSB is confirmed TAA (Trade Agreements Act) compliant, making it suitable for government, GSA schedule, and federal contractor projects where country-of-origin compliance is required.

Q: What finish color is the 4CTCSB?

A: The 4CTCSB is finished in satin brass — a warm metallic tone suited to executive, hospitality, and upscale commercial interiors.

Q: What cover style does the 4CTCSB use — surface or flush?

A: The 4CTCSB uses a surface cover style, meaning it installs at or just above the finished floor plane. This is distinct from fully flush-recessed covers and is appropriate for retrofit applications or substrates where precise core depth matching is not practical.

Q: What receptacle type does the 4CTCSB accommodate?

A: The 4CTCSB uses a standard receptacle type — no specialty inserts or proprietary tooling required.

Q: Which poke-through device family is the 4CTCSB designed for?

A: The 4CTCSB is designed for the Middle Atlantic 4AT Surface Style Evolution poke-through device family. Confirm compatibility with your specific base unit before ordering.

The detail that gets overlooked on poke-through installs is the cover — and the 4CTCSB in satin brass is the kind of finish specification that gets called out explicitly in interior design packages for boardrooms and hospitality spaces. If your project spec says satin brass and you order the wrong finish, you're going back to the site. The surface cover style on the 4CTCSB also gives you some tolerance on retrofit jobs where you can't guarantee the floor build-up matches what the flush-mount variant wants.

Technical Highlights:

• TAA Compliance: Confirmed for this SKU — directly relevant on any government or GSA-schedule project where the full poke-through assembly needs to clear country-of-origin review, not just the active electronics.
• Surface Cover Geometry: Installs above the floor plane, removing the precision depth-matching requirement that flush covers impose — a practical win on tile or hardwood retrofits.
• Satin Brass Finish: A specified aesthetic choice, not a stock default — match it deliberately to the hardware schedule in the room's finish plan.

Deployment Considerations:

• Verify the 4CTCSB is matched to the correct 4AT base device in your poke-through assembly before ordering — surface covers are not cross-compatible with all base configurations in the family.
• Shipping dimensions are 5.63" × 5.63" × 5.5" — plan staging accordingly on large multi-floor projects where you're ordering covers in volume alongside base units.

The 4CTCSB is the right call for upscale conference room, boardroom, or hotel meeting space deployments where the finish schedule specifies satin brass and the floor substrate makes a surface-mount approach more practical than a precision flush fit.
