Middle Atlantic 8IN Stem Assembly - 8STC

Middle Atlantic 8STC 8-Inch Stem Assembly for Recessed Poke-Thru Devices

Overview

The Middle Atlantic 8STC is an 8-inch stem assembly designed for use with Middle Atlantic's 8AT Evolution recessed poke-thru device family. If you're finishing a conference room, huddle space, or AV-integrated work surface and need the correct stem depth to position a poke-thru flush and stable within your table substrate, this is the component to spec. The 8STC ships in silver and is not prewired, giving integrators full control over cable routing and connector population at installation time.

At 9 in × 9 in × 16.25 in (22.9 cm × 22.9 cm × 41.3 cm), the assembly provides the vertical reach needed for thicker table surfaces or raised-floor applications where standard shorter stems fall short. TAA compliance makes the Middle Atlantic 8STC a viable procurement option for federal, state, and local government projects subject to Trade Agreements Act sourcing requirements — an often-overlooked detail that can stall a government AV deployment at the last mile.

Key Features

• 9 × 9 × 16.25-inch form factor: The 16.25-inch depth accommodates thicker conference table substrates or applications where a standard stem would leave the poke-thru proud of the surface. Verify your table cutout depth before ordering — undersizing the stem is a common field error on AV infrastructure projects.
• Not prewired: Blank stem means your team specifies and populates exactly the connectors and cables the end user needs — HDMI, USB-C, power, or combinations — without paying for pre-terminated configurations you'll rewire anyway.
• Silver finish: Coordinates with standard conference furniture and Middle Atlantic's broader poke-thru ecosystem; specify at time of order since finish options on surface-mounted AV components are rarely field-swappable.
• TAA compliant: Sourced to meet Trade Agreements Act requirements, making the 8STC eligible for GSA schedule and government contract procurement without a country-of-origin exception. Confirm TAA requirements with your contracting officer — compliance status applies to the stem assembly itself.

Integration & Compatibility

The 8STC is engineered as a component of Middle Atlantic's 8AT Evolution poke-thru device platform. Before ordering, confirm that your target poke-thru base unit accepts this stem depth, and verify table substrate thickness against the 16.25-inch assembled depth. If your installation uses a thinner table or requires a shorter reach, check Middle Atlantic's stem assembly lineup for the correct depth variant. Pairing the correct stem with the appropriate insert modules (sold separately) completes the assembly for final surface installation.

Frequently Asked Questions

A: The 8STC measures 9 inches wide × 9 inches tall × 16.25 inches deep (22.9 cm × 22.9 cm × 41.3 cm).

Q: What color is the 8STC?

A: The 8STC ships in silver finish.

Q: Which poke-thru device family is the 8STC designed for?

A: The 8STC is part of Middle Atlantic's 8AT Evolution recessed poke-thru device platform. Confirm compatibility with your specific base unit before ordering.

The Middle Atlantic 8STC comes up in government and corporate AV bids specifically because of two things: its 16.25-inch stem depth and TAA compliance. Most conference table installations run into trouble when the integrator specs a stem that's 2–3 inches short for a 2-inch-thick solid-wood or composite table — the poke-thru sits proud, the surface ring gaps, and you're back on-site for a swap. The 8STC's depth covers the scenarios where standard shorter stems don't reach.

Technical Highlights:

• 16.25-inch depth: Handles thicker table substrates that standard stems can't reach flush — measure the table cutout before finalizing the stem SKU.
• Not prewired: Blank configuration gives the integrator full connector choice; no rework cost from pre-terminated SKUs that don't match the end user's actual port mix.
• TAA compliance: Qualifies for GSA and government contract procurement without country-of-origin exceptions — a procurement gate that catches many AV components late in the bid cycle.

Deployment Considerations:

• The 9 × 9-inch footprint requires a matching cutout in the table surface — coordinate with the furniture vendor or fabricator early; field-cutting a finished conference table is a high-risk last resort.
• The 8STC is a stem assembly only — insert modules, power, and connectivity components are sourced separately. Budget and schedule for those line items; the stem alone does not complete the installation.

The 8STC is the right spec for government conference rooms and corporate boardrooms where table substrate depth and TAA sourcing requirements rule out standard-depth stems — not a universal fit, but exactly right when those two constraints apply.
