Middle Atlantic 4CTCBK Surface-Style Poke-Thru Cover Assembly

Overview

The Middle Atlantic 4CTCBK is a surface-style cover assembly designed for the 4AT Evolution poke-thru device series. At 5.63" x 5.63" x 5.5" (143.1 x 143.1 x 139.7 mm), this black cover sits proud of the floor surface rather than flush-recessing into it — the right choice when a core-drill or recessed installation isn't feasible or when the floor construction (raised access flooring, concrete slab, existing tile) makes a true flush mount impractical. If you're finishing a conference room, boardroom, or AV presentation space and need a clean cable-access point at the table or floor, the 4CTCBK gives you a finished, professional appearance without a full floor-box rough-in.

The standard receptacle configuration supports typical power and data termination in the 4AT poke-thru family. The all-black finish integrates with dark carpet, dark flooring, and under-table cable management schemes common in corporate AV and security head-end rooms.

For a full view of the Middle Atlantic product line including rack systems, power, and cable management, the brand catalog covers the complete infrastructure stack. This cover pairs directly with cable management accessories and is a common finish component on AV and security integration projects using Middle Atlantic furniture and mounting systems.

Key Features

• Surface-Mount Profile (5.5" height): at 5.5" proud of the surface, this cover is explicitly designed for installations where recessing into the floor isn't an option — saves the cost and labor of core-drilling or subfloor modification while still delivering a permanent, organized cable access point.
• 5.63" x 5.63" footprint: compact enough to fit under most conference table legs or between workstation runs without creating a trip hazard or blocking chair movement — verify clearance before ordering if space is tight.
• Standard receptacle type: accepts standard power and low-voltage terminations in the 4AT Evolution series — confirm your specific receptacle module selections separately, as the cover assembly and inserts are specified independently in the Middle Atlantic poke-thru system.
• Black finish: matches dark commercial carpet and under-table environments; reduces visual prominence in presentation rooms where a chrome or white cover would draw attention away from the display or seating area.
• Middle Atlantic 4AT Evolution platform compatibility: this cover is part of the floor box and poke-thru device category within the 4AT surface-style Evolution line — pairing with the correct base unit is required for a complete assembly.

Integration and Compatibility

The 4CTCBK is the cover component for the Middle Atlantic 4AT surface-style poke-thru system. A complete installation requires the matching base/floor unit and your chosen receptacle inserts (power, data, AV) specified separately. Confirm compatibility with your specific 4AT base model before ordering — cover style (surface vs. flush) and base model must match. This cover does not retrofit onto flush-style or competitive poke-thru bases.

Typical deployment contexts include corporate conference rooms, security operations centers, AV integration head-ends, and training rooms where surface-mount cable access is preferred over a full floor-box rough-in. Pair with Middle Atlantic rack power and cable management for a complete infrastructure finish.

Frequently Asked Questions

Q: What is the overall size of the 4CTCBK cover assembly?

A: The 4CTCBK measures 5.63" x 5.63" x 5.5" (143.1 x 143.1 x 139.7 mm). The 5.5" height reflects the surface-mount profile — it sits above the floor rather than recessing flush.

Q: Is the 4CTCBK a flush or surface-mount cover?

A: Surface-mount. The 4CTCBK uses Middle Atlantic's surface-style cover design, which is appropriate when core-drilling or recessed floor-box installation is not feasible.

Q: What receptacle type does the 4CTCBK support?

A: The 4CTCBK is configured for standard receptacle types within the 4AT Evolution poke-thru system. Specific power and data insert modules are specified and ordered separately.

Q: What color is the 4CTCBK?

A: Black. The all-black finish suits dark commercial carpet and under-table environments in conference and presentation spaces.

Q: Does the 4CTCBK include the base unit and receptacle inserts?

A: No. The 4CTCBK is the cover assembly only. A complete poke-thru installation requires the matching 4AT base unit and separately specified receptacle insert modules.

Jerry Tildsen

The 4CTCBK comes up on almost every corporate AV or SOC finish-out where the floor construction rules out a recessed box — the 5.5" surface profile is the spec that tells you immediately whether this fits your install or not. If you have raised access flooring or a slab you can't core, this is the practical path; if you can go flush, a recessed cover gives you a cleaner trip-hazard profile.

Technical Highlights:

• Surface-mount height (5.5"): at nearly 5.5 inches proud of the floor, confirm clearance under fixed furniture before specifying — the 5.63" x 5.63" footprint is compact, but the height is the variable that trips up installations on low-clearance table bases.
• Standard receptacle configuration: compatible with standard insert modules in the 4AT Evolution poke-thru system — this is the cover only, not a complete assembly; budget for the base unit and inserts as separate line items.
• Black finish: the all-black color reads as nearly invisible against dark commercial carpet — a deliberate choice for presentation rooms where a silver or white cover would compete visually with display surfaces.

Deployment Considerations:

• Verify your base unit model is the 4AT surface-style variant before ordering the 4CTCBK — surface-style covers do not interchange with flush-style bases in the Middle Atlantic poke-thru line.
• The 5.5" height is the most common specification oversight on this part: measure clearance under fixed seating and table aprons before committing, especially in stadium-seating training rooms with fixed furniture runs.

Best fit for corporate conference rooms, boardrooms, and security operations centers on concrete slab or raised-access floors where a surface-mount cable access point is the only practical finish option.
