Middle Atlantic NM Power BOX Ivory - PSB1V

Middle Atlantic PSB1V Non-Metallic One-Gang Device Box Fitting

Overview

The Middle Atlantic PSB1V is an ivory, non-metallic one-gang device box fitting engineered specifically for the Eclipse raceway series. At 4-3/4" x 3" x 1-3/4", it provides a clean, finished mounting point wherever a single-gang outlet, keystone jack, or NEMA faceplate needs to surface from a Middle Atlantic PN-series raceway run. If you're wiring structured cabling, low-voltage data drops, or in-wall power along a raceway backbone, this is the box that converts the raceway's channel into a usable device location without cutting into drywall or pulling a separate box rough-in.

The PSB1V fits the PN03, PN05, and PN10 series Eclipse raceways — three of the most widely deployed surface-mount raceway widths in commercial AV and security installations. Matching the ivory color keeps the installation visually consistent on standard office or corridor walls without requiring paint touch-ups.

Key Features

• Single-Gang NEMA Faceplate Acceptance: The box is dimensioned to accept any standard single-gang NEMA faceplate, so you're not locked into proprietary hardware. This means any off-the-shelf keystone faceplate, Decora outlet cover, or blank plate drops straight in — no adapters, no sourcing delays on a job site.
• Keystone Jack Compatibility: Designed to accept keystone jacks directly, this fitting handles Cat5e/Cat6 data terminations, fiber adapters, HDMI keystone inserts, and coax snap-ins without modification. For AV and security integrators terminating multiple media types along the same raceway run, that flexibility matters.
• Four-Side Twistouts: Twistout knockouts on all four sides let you route the raceway entry from whichever direction the run approaches — top, bottom, left, or right. That's a practical advantage when field conditions don't cooperate with a planned layout and you need to adjust on the fly.
• Non-Metallic Construction: The non-metallic body eliminates corrosion risk in environments with humidity or cleaning chemicals, and it won't interfere with nearby low-voltage signaling the way metal boxes can in dense wiring situations. It's also lighter and easier to handle during overhead or tight-corner installs.
• Eclipse Raceway Series Integration: Compatibility with PN03, PN05, and PN10 raceways means the PSB1V spans the full width range of Middle Atlantic's cable management Eclipse line. Whether your run is a narrow 1-3/16" channel or a wider 2" trunk, there's a matching raceway this box supports.
• Ivory Finish: Color-matched to the Eclipse raceway system's standard ivory finish. Consistent aesthetics across the entire run matters on commercial projects where the finished appearance is part of the deliverable — especially in healthcare, hospitality, and corporate environments.
• Compact Profile — 4-3/4" x 3" x 1-3/4": The shallow 1-3/4" depth keeps the box from protruding unnecessarily off the wall surface, which is relevant when installing near door frames, furniture, or other obstructions that a deep box would conflict with.

Integration & Compatibility

The PSB1V is built for the Middle Atlantic Eclipse raceway platform, specifically the PN03, PN05, and PN10 series. Before ordering, confirm which raceway width is installed on your project — the PN03 (1-3/16" wide), PN05 (1-11/16" wide), and PN10 (2" wide) each have different channel dimensions, and this box fitting bridges the gap between the raceway channel and a standard device location. If you're mid-run on a structured power or data distribution layout and need to add a device drop, the PSB1V integrates cleanly without cutting into the wall or interrupting the raceway run continuity.

For integrators specifying full raceway systems, pair the PSB1V with matching Middle Atlantic Eclipse raceway sections, inside/outside corner fittings, and flat elbows to maintain a consistent system throughout. The single-gang NEMA format also ensures compatibility with standard keystone patch panels and low-voltage mounting brackets if a multi-port location is needed — use multiple PSB1V units side by side on wider raceway sections.

Frequently Asked Questions

Q: Which Middle Atlantic raceways is the PSB1V compatible with?

A: The PSB1V is compatible with the PN03, PN05, and PN10 series Eclipse raceways. Verify which raceway width is installed before ordering to confirm the correct fit.

Q: Will the PSB1V accept standard keystone jacks for Cat6 or HDMI terminations?

A: Yes. The PSB1V accepts single-gang NEMA faceplates and keystone jacks, making it suitable for Cat5e/Cat6, fiber, HDMI, and coax keystone inserts without modification.

Q: How many sides have twistout knockouts on the PSB1V?

A: The PSB1V has twistout knockouts on all four sides, allowing raceway entry from the top, bottom, left, or right depending on how the run approaches the device location.

Q: What are the dimensions of the PSB1V?

A: The PSB1V measures 4-3/4" x 3" x 1-3/4" (L x W x D). The shallow 1-3/4" depth keeps wall protrusion minimal.

Q: Is the PSB1V metal or plastic?

A: It is non-metallic (plastic), which resists corrosion and avoids potential interference with adjacent low-voltage signal wiring.

Q: What color is the PSB1V?

A: Ivory, matching the standard Eclipse raceway finish for a consistent appearance across the full raceway installation.

The PSB1V is a straightforward component, but the four-side twistout knockout design is the spec I point integrators to when they're concerned about field flexibility. On a commercial retrofit where the raceway run was planned on paper but the walls have door frames, HVAC drops, and furniture clusters, being able to pop a knockout from any of the four sides means you're not boxed into a single cable entry angle. At 4-3/4" x 3" x 1-3/4", it also sits close to the wall — important when you're dropping a device location near a door casing or under a window sill.

Technical Highlights:

• Four-Side Twistouts: Entry from any of four sides accommodates field deviations from the planned raceway path without requiring a different fitting or cutting additional material.
• NEMA + Keystone Compatibility: Accepts any standard single-gang NEMA faceplate or keystone jack insert — covers power, data, AV, and coax termination in a single box type, reducing the number of fitting SKUs you need to stock.
• Non-Metallic Body: Eliminates galvanic corrosion risk in humid environments (server closets, mechanical rooms) and reduces signal coupling concerns where multiple low-voltage conductors converge at a single device location.

Deployment Considerations:

• Confirm raceway width before ordering — the PSB1V spans PN03, PN05, and PN10, but not all Middle Atlantic Eclipse fittings are cross-compatible across widths. Mismatching raceway width to box fitting is the most common field error on these installations.
• The ivory finish matches the standard Eclipse raceway color. If your project spec calls for white or another color, verify the raceway finish before committing — re-painting non-metallic fittings is possible but adds labor and risks paint adhesion issues over time.

The PSB1V is the right call on corporate, healthcare, or hospitality surface-mount wiring projects where the Eclipse raceway is already specified and you need device locations that terminate cleanly, match the raceway aesthetic, and accept standard off-the-shelf faceplates without sourcing proprietary hardware.
