Middle Atlantic 525G In-Floor Pedestal Service Fitting with Duplex Receptacle Opening

Overview

The Middle Atlantic 525G is a four-piece in-floor pedestal service fitting designed for controlled furniture and office workspace environments where clean power and signal access needs to surface at the desk or workstation level — without exposed conduit runs or surface-mounted raceway compromising the floor plan. The 525G expands service range to include audio/video devices, making it a practical choice for conference rooms, executive suites, and training spaces where A/V integration sits alongside standard power delivery.

In-floor service fittings solve a specific architectural problem: how do you bring a 20A duplex receptacle and communications pathways up through the floor slab in a way that looks intentional, accommodates furniture repositioning, and survives day-to-day workplace use? The 525G answers that with a modular four-piece assembly that mounts in-floor, supports a duplex receptacle opening on both sides, and integrates cleanly into cable management workflows for commercial interiors.

Key Features

• Four-Piece In-Floor Construction: The modular assembly approach means individual components can be staged, adjusted, and finished on-site without having to spec a single-cast fitting that may not align precisely with slab cutouts or raised-floor grid intersections. For integrators coordinating with GCs on floor core placements, this matters — field adjustability reduces rework.
• Duplex Receptacle Opening on Both Sides: Access from both sides of the fitting means you can service the receptacle or route cables without fully removing the fitting from the floor. In active office environments where downtime for moves/adds/changes is a real cost, bilateral access shortens the service window.
• 20A Duplex Receptacle Support: The 20A rating gives you headroom for workstation loads that include monitors, docking stations, and powered A/V equipment — not just phone chargers. That extra ampacity margin matters in conference rooms running projectors, displays, or audio DSP gear simultaneously on the same circuit.
• Audio/Video Device Integration: The 525G is explicitly designed to include A/V device servicing in its coverage scope, not just standard power. For rooms where HDMI, USB-C, or low-voltage signal connections need a floor-level access point, this fitting provides the opening; you supply the keystone or insert appropriate to your signal type.
• In-Floor Mounting: Flush in-floor installation eliminates the trip-hazard profile of surface-mounted solutions and supports formal ADA-compliant or high-traffic space designs. Once installed, the fitting is essentially invisible until accessed — appropriate for boardrooms, training centers, or any space where aesthetics are part of the specification.
• Controlled Workspace Fit: Targeted at controlled furniture and office workspace installations, this fitting is not a rough-service or industrial product — it is matched to finished commercial interiors where the floor system, furniture layout, and cable management are coordinated from the start. That positioning also means finish quality and dimensional tolerances are appropriate for visible commercial environments, not just utility spaces.

Integration & Compatibility

The 525G sits within the broader Middle Atlantic cable management and workspace infrastructure line, making it a natural companion to rack systems, furniture raceways, and structured cabling pathways deployed in the same commercial project. It is compatible with standard in-floor poke-through installation practices and should be coordinated with the floor system type — whether poured concrete slab with a core bore, or raised-access flooring with a pre-formed tile opening.

For A/V integrators specifying this alongside A/V furniture and conference room infrastructure, the duplex opening accommodates standard decora-style receptacles and keystone modules depending on how the fitting is populated, giving flexibility in how power and signal are brought to the surface. Confirm rough-in dimensions and floor system depth with the project GC before committing to the cutout location — in-floor service fittings are significantly harder to relocate post-pour than surface systems.

When planning power distribution for multi-device conference or huddle rooms, pair this fitting with appropriate power distribution units to ensure the upstream circuit matches the 20A rating this fitting is designed to support.

Frequently Asked Questions

Q: What type of installation does the Middle Atlantic 525G require?

A: The 525G is an in-floor service fitting. It requires an in-floor mounting location — either a cored opening in a concrete slab or a compatible cutout in a raised-access floor panel. It is not a surface-mount or wall-mount product.

Q: Does the 525G include a receptacle, or is the receptacle purchased separately?

A: The 525G provides a duplex receptacle opening — it is designed to accept a 20A duplex receptacle. The receptacle itself and any keystone signal modules are typically specified and purchased separately to match the electrical and A/V requirements of the installation.

Q: Can the 525G accommodate audio/video connections, or is it power-only?

A: Yes. The 525G is specifically designed to expand service range to include audio/video devices, not just power. The opening and construction support A/V signal connectivity alongside the 20A duplex power function.

Q: Is the 525G suitable for high-traffic commercial spaces?

A: The 525G is targeted at controlled furniture and office workspace installations — conference rooms, executive offices, training spaces, and similar finished commercial interiors. It is not rated as a rough-service or industrial fitting, so it is best specified for environments with coordinated furniture layouts rather than open warehouse or industrial floors.

Q: How does the four-piece construction benefit installation?

A: The modular four-piece design allows for field adjustment during installation, which simplifies alignment with slab cutouts or raised-floor openings. Individual components can be staged and finished on-site, reducing the rework risk that comes with single-piece fittings that must align perfectly at rough-in.

Q: What is the advantage of duplex openings on both sides of the fitting?

A: Bilateral access means you can service or modify the receptacle and cabling from either side of the fitting without fully removing it from the floor — shortening the service window for moves, adds, and changes in active office environments.

Eden Phillips

The Middle Atlantic 525G comes up regularly on commercial office A/V projects where the architect has specified in-floor power and signal access and the integrator needs a fitting that can handle both a 20A duplex receptacle and A/V connectivity in the same floor core. The bilateral duplex opening is the detail that makes this fitting worth specifying over a basic single-access poke-through — it means your low-voltage technician can get at the signal side without disturbing the electrical termination on the other side of the fitting.

Technical Highlights:

• Four-Piece Modular Assembly: Field-adjustable construction reduces the alignment risk at rough-in — critical when coordinating floor core placement with a GC on poured-slab projects where repositioning post-pour is not an option.
• 20A Duplex Receptacle Opening: The 20A rating supports real conference room loads — dual displays, a DSP processor, and a laptop docking station can run on a single 20A circuit without nuisance tripping, which matters in rooms where the electrical panel is not nearby.
• Audio/Video Device Scope: The 525G is explicitly designed to service A/V devices, not just power outlets — this is the spec that distinguishes it from basic power-only floor boxes when you are coordinating with an AV design that includes in-floor signal drops.

Deployment Considerations:

• Confirm slab or raised-floor depth and cutout dimensions before committing to the rough-in location — in-floor fittings are difficult to relocate post-installation, and the four-piece assembly still requires a precise floor opening to seat correctly.
• The 525G is designed for controlled office and furniture environments, not industrial or high-traffic open floor installations — if the project involves frequent heavy-cart or forklift traffic over the fitting location, this is not the right product for that zone.

This fitting is a solid specification for corporate conference rooms, executive boardrooms, and training centers where the furniture layout is fixed, the floor system is finished, and the A/V design calls for flush in-floor power and signal access points that disappear when not in use.
