Middle Atlantic NM ONE Series II Small DA - PDB1S2FW

Middle Atlantic PDB1S2FW NM One Series II Small DA Surface Mount Box

Overview

The Middle Atlantic PDB1S2FW is a small direction adapter (DA) surface mount box designed as part of the NM One Series II cable management ecosystem. As an elbow box connector fitting within the coupler connector category, the PDB1S2FW gives integrators a clean, code-compliant way to transition cable runs at corners and direction changes — whether you're routing signal or power cables through an Eclipse Raceway system or running it as a standalone surface-mount enclosure independent of a larger raceway infrastructure.

This is the kind of fitting that separates a professional installation from a field improvisation. Rather than bending cables around a sharp corner or leaving an exposed elbow in a finished space, the PDB1S2FW provides a purpose-built enclosure that keeps the transition contained, protected, and visually consistent with the rest of the raceway run. For integrators working in commercial environments where appearance and cable integrity both matter, that distinction is worth calling out.

Key Features

• Elbow Box Form Factor: The direction-adapter geometry handles 90-degree and directional transitions in a single fitting — no field-fabricated elbows, no exposed bends. This keeps cable bend radius within acceptable limits and eliminates stress points that can degrade signal or damage jacket insulation over time.
• Surface Mount Design: Mounts directly to walls, columns, or structural surfaces without requiring raceway track to be continuous through the corner. This gives you flexibility on runs that hit structural interruptions or need to change plane from horizontal to vertical.
• NM One Series II Compatibility: Engineered to integrate with Middle Atlantic's NM One Series II cable management line, so the PDB1S2FW matches the dimensional and aesthetic profile of other fittings in the series — important in finished commercial spaces where mismatched raceway components stand out.
• Eclipse Raceway or Standalone Use: Works within a full Eclipse Raceway deployment or independently as a standalone surface-mount box. That dual-mode compatibility means you can use it to anchor a run that starts or terminates at a wall box, not just mid-run transitions.
• Coupler Connector Category: Classified as a coupler connector fitting, so it's designed to join and redirect raceway sections — not just cap or terminate them. This matters when specifying fittings on a raceway BOM: the PDB1S2FW is a transition component, not an end piece.
• Commercial-Grade Construction: Built to Middle Atlantic's commercial infrastructure standards, consistent with the NM One Series II line's use in AV, security, and IT cable management applications where fittings need to hold up through installation handling and long-term environmental exposure in interior commercial spaces.

Integration & Compatibility

The PDB1S2FW is specified for use with the Eclipse Raceway system or as a standalone surface-mount fitting. It is part of the NM One Series II family from Middle Atlantic, which means it shares dimensional compatibility with other Series II fittings, couplers, and covers. When building out a raceway layout, this fitting slots in at directional change points — corners, offsets, and plane transitions — where a straight section cannot continue.

For system integrators specifying Middle Atlantic cable management on commercial security or AV jobs, the PDB1S2FW is the correct fitting to call out on drawings wherever a small elbow box is needed at a surface-mount transition point. Confirm raceway channel width compatibility with your specific Eclipse Raceway run before ordering — the Series II line includes multiple channel sizes, and direction adapters are size-specific.

Frequently Asked Questions

Q: What is the PDB1S2FW used for?

A: The PDB1S2FW is a small direction adapter (DA) surface mount elbow box connector fitting. It is used to transition cable runs at directional changes in the NM One Series II cable management system, either as part of an Eclipse Raceway installation or as a standalone surface-mount enclosure.

Q: Is the PDB1S2FW compatible with Eclipse Raceway?

A: Yes. The PDB1S2FW is designed for use with Eclipse Raceway or as a standalone surface-mount application, per manufacturer documentation.

Q: Does the PDB1S2FW work as a standalone fitting, or does it require a full raceway system?

A: It works both ways. The PDB1S2FW can be integrated into a full Eclipse Raceway run or mounted independently as a standalone surface-mount box where no continuous raceway is required.

Q: What series does the PDB1S2FW belong to?

A: The PDB1S2FW is part of the Middle Atlantic NM One Series II cable management line, designed to match the dimensional and aesthetic profile of other Series II fittings and couplers.

Q: What type of fitting is the PDB1S2FW — is it a termination or a transition component?

A: The PDB1S2FW is a coupler connector (transition component), specifically an elbow box direction adapter. It joins and redirects raceway sections at directional change points rather than capping or terminating a run.

As someone who has spec'd a lot of raceway runs for commercial security installs, the detail I keep coming back to on the PDB1S2FW is its dual-mode compatibility — it fits into an Eclipse Raceway system or mounts standalone. That sounds minor until you're on a job where your raceway run terminates at a camera rough-in box that doesn't have continuous track behind it. The PDB1S2FW covers that scenario without a field workaround.

Technical Highlights:

• Elbow Box Form Factor: Purpose-built directional transition means cable bend radius is controlled by the fitting geometry, not by how much force the installer used at the corner — a real factor on Cat6 and coax runs where tight bends cause measurable signal degradation.
• NM One Series II Series Membership: Dimensional compatibility with the Series II line means fittings, covers, and couplers from the same family will align and close properly — no gaps, no mismatched profiles in finished commercial spaces.
• Surface Mount Construction: Designed for direct wall or column mounting, so it works on runs that need to change plane or navigate structural interruptions without requiring continuous raceway track through the transition point.

Deployment Considerations:

• Confirm that the PDB1S2FW channel width matches your specific Eclipse Raceway run before ordering — the NM One Series II line includes multiple channel sizes and direction adapters are size-specific, not universal across the family.
• This is a coupler connector fitting (transition component), not an end cap or termination box — make sure your raceway BOM distinguishes between the two if you are also specifying end pieces on the same run.

The PDB1S2FW is best suited for commercial security and AV cable management runs in finished interior spaces — offices, lobbies, and corridors — where both cable protection and visual consistency with the surrounding raceway system are part of the installation standard.
