Middle Atlantic 817TAL-BZ 1-Gang Flangeless Trim Ring, Bronze

The Middle Atlantic 817TAL-BZ is a 1-gang flangeless trim ring finished in bronze over an aluminum and brass build, made for wall-box and connectivity plate installations where a clean, flush finish matters more than a visible mounting lip. Integrators pulling finish hardware for AV racks, table boxes, and wall plates in conference rooms, lobbies, and control rooms use this trim to close out a 1-gang opening without a border interrupting the wall or furniture surface. The 817TAL-BZ (often searched as 817TAL BZ) measures 4.5'' x 3.5'' (114mm x 89mm), sized for standard single-gang cutouts.

Overview

This trim ring is a finish component, not a functional device — it dresses out a single-gang opening with a flangeless profile, meaning there's no raised lip or border sitting proud of the wall or millwork. That matters on projects where the trim needs to sit flush against a painted wall, a veneer panel, or a conference table insert without drawing a visual line around the opening. The bronze finish is built to read as a neutral, low-profile accent against darker wood tones or bronze-toned hardware runs, rather than the brighter aluminum or white finishes typically stocked for standard drywall installs.

Key Features

• Flangeless design: No raised border around the opening, so the trim sits flush with the mounting surface — the right call when the surrounding wall or table finish needs to stay visually clean instead of framed by a lip.
• 1-gang configuration: Sized to close out a single standard gang opening, matching the majority of table boxes, wall plates, and connectivity cutouts used in conference room and control room builds.
• Bronze finish over aluminum: Gives installers a darker, warmer finish option for projects where brushed aluminum or white plastic trim would clash with wood paneling, bronze door hardware, or other dark-toned architectural finishes.
• Powder-coated aluminum and brass construction: Powder coating resists scuffing and finish wear on a component that gets handled repeatedly during installation and ongoing cable changes — a better long-term look than paint on high-touch trim.
• Compact footprint — 4.5'' x 3.5'' (114mm x 89mm): Confirms fit against a standard single-gang box before ordering, so there's no surprise when the trim reaches the job site.
• TAA compliant: Relevant for integrators bidding government, education, or other public-sector AV contracts that require Trade Agreements Act compliance on hardware line items.
• PEP ecopassport environmental certification: Gives specifiers a documented environmental profile to cite when a project scope requires sustainability or environmental product declarations for finish hardware.

Integration & Compatibility

The 817TAL-BZ is a finish-hardware accessory intended to pair with a 1-gang table box, wall plate, or connectivity enclosure sized for a standard single-gang cutout — confirm your box or plate is rated for a flangeless trim before ordering, since flanged and flangeless trims are not interchangeable. For broader planning on how table boxes, wall plates, and trim rings fit into a room's cable and connectivity plan, a PoE and connectivity planning guide is a useful reference before finalizing hardware counts. This trim belongs alongside other AV racks and mounts hardware on a project BOM, and integrators sourcing the full Middle Atlantic product line can match finishes across trim rings, table boxes, and rack accessories on the same job. If the room also needs surveillance coverage, pair the connectivity buildout with a look at IP cameras for the same space, and round out the rack build with PoE switches sized to the room's device count.

Frequently Asked Questions

Q: Is the 817TAL-BZ TAA compliant?

A: Yes, the 817TAL-BZ is TAA compliant, which matters for integrators bidding government or public-sector AV projects with Trade Agreements Act sourcing requirements.

I get asked why anyone would spec a flangeless trim over a standard flanged one, and the 817TAL-BZ is a good example of why: on a conference table box or a finished wall, that raised flange reads as a visible seam the moment the light hits it. The 817TAL-BZ closes out a 1-gang opening flush, in a bronze finish that's meant to disappear against darker wood and metal finishes instead of standing out like the usual aluminum trim.

Technical Highlights:

• 1-gang, 4.5'' x 3.5'' (114mm x 89mm): confirm this against your box cutout before ordering — flangeless trims don't have the forgiveness a flanged lip gives you if the opening runs slightly oversized.
• Powder-coated aluminum and brass: the powder coat is what keeps the bronze finish from scuffing through to bare metal after repeated cable changes at a table box or wall plate.
• TAA compliant: worth flagging on any public-sector or government BOM where sourcing rules apply to finish hardware, not just active electronics.

Deployment Considerations:

• Flangeless and flanged trims are not interchangeable — verify your table box or wall plate is drilled for a flangeless ring before this ships to the job site.
• Bronze is a finish match play: pull this when the room has dark wood millwork or bronze door hardware, not as a default over Middle Atlantic's standard aluminum finish options.

This is the right trim for a boardroom or executive conference room build where the table box needs to disappear into a walnut or dark veneer table rather than stand out in brushed aluminum — spec the 817TAL-BZ when finish continuity is part of the design brief, not an afterthought.
