Middle Atlantic 6IN Setm Assembly - 6STC

Middle Atlantic 6STC 6-Inch Stem Assembly for Poke-Thru Devices

Overview

The Middle Atlantic 6STC is a 6-inch stem assembly designed for use with the 6AT Evolution Poke-Thru recessed floor device family. At 7 inches square and 16.25 inches deep, this stem component provides the structural extension that positions the poke-thru housing at the correct floor-surface elevation — a detail that separates a clean, professional installation from one that sits proud of the floor or recesses too far to function properly. If you are specifying or replacing stem components for a Middle Atlantic poke-thru system, the 6STC is the part that bridges the floor cutout depth to the device housing above it.

TAA compliance is confirmed for the 6STC, which matters for government facilities, federal integrators, and any project governed by the Trade Agreements Act. Silver finish matches standard poke-thru trim aesthetics in commercial and conference environments.

Key Features

• 16.25-Inch Installation Depth: The 16.25-inch (41.3 cm) depth accommodates typical commercial concrete and raised-floor construction scenarios. Before ordering, verify your floor assembly depth — this stem is sized for a specific installation range, and using the wrong depth will result in a housing that sits incorrectly at the floor surface.
• 7 × 7-Inch Footprint: The 7-inch square (17.8 × 17.8 cm) cross-section is matched to the 6AT Evolution Poke-Thru housing family. This is not a universal stem — confirm your housing model before specifying.
• TAA Compliant: Verified TAA compliance on the 6STC means this component qualifies for GSA schedules and federally funded projects where Trade Agreements Act sourcing is required. One less compliance checkbox for your submittal package.
• Silver Finish: Factory silver color coordinates with standard commercial poke-thru trim rings and cover plates, keeping the floor installation visually consistent without field finishing.
• Not Prewired: The 6STC ships as a mechanical assembly only — no pre-installed wiring harness. Field wiring is handled during installation, which is standard practice for stem assemblies of this type and gives the installer full control over cable routing and termination.
• Zero Duplex Outlets: This is a stem/structural component, not a power module. Outlet modules, data inserts, and cover plates are specified and ordered separately as part of the complete poke-thru device assembly.

Integration & Compatibility

The 6STC is designed for the Middle Atlantic 6AT Evolution Poke-Thru recessed device family. When specifying a complete poke-thru system for a conference room, boardroom, or open-plan workspace, the stem assembly is one component in a modular stack that includes the housing, insert modules (power, data, AV), and trim cover. Consult the 6AT Evolution product family documentation to confirm which stem depth matches your floor construction. For projects involving AV infrastructure rough-in, coordinate stem selection with your floor thickness measurements before the concrete pour or raised-floor panel installation — correcting a stem depth error after the floor is finished is a significant rework item. If your project includes network switching to support AV or security endpoints at the floor level, review compatible network switches for the data insert modules in the same assembly.

Frequently Asked Questions

Q: Is the Middle Atlantic 6STC TAA compliant?

A: Yes. The 6STC is confirmed TAA compliant, making it suitable for GSA schedules and federally funded projects governed by the Trade Agreements Act.

Q: What are the dimensions of the 6STC?

A: The 6STC measures 7 inches wide × 7 inches tall × 16.25 inches deep (17.8 × 17.8 × 41.3 cm).

Q: Does the 6STC come prewired?

A: No. The 6STC ships as a mechanical stem assembly without pre-installed wiring. All wiring is completed in the field during installation.

Q: Does the 6STC include power outlets?

A: No. The 6STC is a structural stem component with zero duplex outlets. Power and data modules are specified separately as part of the complete poke-thru device assembly.

Q: What color is the 6STC?

A: The 6STC has a silver finish, consistent with standard commercial poke-thru trim aesthetics.

Q: Which poke-thru device family does the 6STC work with?

A: The 6STC is designed for the Middle Atlantic 6AT Evolution Poke-Thru recessed device family. Confirm your floor depth and housing model before ordering to ensure the stem depth is correct for your installation.

Ted Perry

The Middle Atlantic 6STC is a detail-level component, but getting the stem depth wrong on a poke-thru installation is the kind of mistake that costs real money to fix after the floor is finished. The 16.25-inch depth on the 6STC is the critical number — that is the spec you match to your floor construction thickness before you specify this part.

Technical Highlights:

• 16.25-Inch Depth: Sized for specific floor assemblies — verify your floor construction depth against this number before ordering. A stem that is too long or too short will prevent the housing from sitting flush at the finished floor surface.
• TAA Compliance: Confirmed for the 6STC, which clears the sourcing requirement for government and federally funded facilities without needing a separate compliance review for this component.
• 7 × 7-Inch Cross-Section: Matched to the 6AT Evolution housing family — this is not a universal part. Cross-reference the housing model in your bill of materials before placing the order.

Deployment Considerations:

• Coordinate stem selection with your floor thickness measurement before concrete pour or raised-floor panel installation — correcting the wrong stem depth after the fact is a significant field rework item that affects both schedule and cost.
• The 6STC ships with no prewired harness and no outlet modules — budget for separate power and data insert modules when building your complete poke-thru assembly BOM.

The 6STC is the right specification for 6AT Evolution poke-thru deployments in conference rooms, boardrooms, and open-plan commercial spaces where the floor construction depth matches the 16.25-inch stem and TAA sourcing compliance is a project requirement.
