Middle Atlantic NM Data BOX FOR ONE CM MO - PDB1CMFW

Middle Atlantic PDB1CMFW Surface Mount Data Box for One CM Module

Overview

The Middle Atlantic PDB1CMFW is a surface mount data box engineered specifically to house a single front-loaded, downward-facing Pass and Seymour module — the kind of low-profile connectivity solution that keeps AV and data terminations clean inside rack rooms, behind panels, and along Eclipse Raceway runs. If you're managing cable terminations in a structured installation where loose keystones or exposed jacks aren't acceptable, this box is the right fitting approach. It drops cleanly into rack accessories and raceway-based installations without requiring custom fabrication or adapter hardware.

The PDB1CMFW is designed for either standalone surface mounting or direct integration into the Middle Atlantic Eclipse Raceway system — giving installers two valid deployment paths depending on the wall or surface topology at the job site. The 1/2-inch trade-size knockout accommodates standard conduit connections, making it straightforward to pull structured cabling through in a code-compliant way. For integrators working the Middle Atlantic catalog across enterprise AV and security infrastructure projects, this box closes the loop on module termination without improvised solutions.

Key Features

• Single CM Module Capacity: Accepts exactly one front-loaded, downward-facing Pass and Seymour module — so you're selecting a termination point, not a multi-port panel. Right for discrete connection locations in clean cable management plans where one port per station is the spec.
• Surface Mount Form Factor: Mounts directly to walls, columns, or raceway surfaces without requiring a flush cut or back-box rough-in. Reduces installation time on finished surfaces and retrofit jobs where cutting isn't an option.
• Eclipse Raceway Compatibility: Designed to pair with Middle Atlantic's Eclipse Raceway system, meaning the box integrates into a pre-existing raceway run without brackets or adapters. If your project already uses Eclipse Raceway for cable management, this box slots into that ecosystem directly.
• Standalone Application Support: When Eclipse Raceway isn't in play, the PDB1CMFW functions as a self-contained surface box — useful for isolated data outlet locations in server rooms, equipment closets, or facility perimeters where running full raceway is overkill.
• 1/2-Inch Trade Size Knockout: The industry-standard 1/2-inch knockout accepts EMT and flexible conduit fittings you already stock. No special fittings, no substitution — keeps the install code-compliant and the conduit run continuous.
• Front-Loaded Module Orientation: The downward-facing front-load design means you can seat and replace the Pass and Seymour module without removing the box from the wall. On live installations or moves/adds/changes, that's faster and less disruptive than rear-access or full-disassembly designs.
• Rack Accessory Classification: Categorized as a rack accessory within structured cable management systems, which means procurement teams can pull this against the same line items as other raceway and termination hardware — simplifies BOM management on larger installations.

Integration & Compatibility

The PDB1CMFW is built around the Pass and Seymour CM module form factor — specifically the front-loaded, downward-facing variant. If your termination plan calls for a different module orientation or a different manufacturer's keystone insert, verify dimensional compatibility before ordering. This box is not a universal keystone plate; it's optimized for the CM module spec.

For Eclipse Raceway installations, the PDB1CMFW attaches directly to the raceway channel, maintaining the clean surface-mounted aesthetic that defines the Middle Atlantic system. For standalone applications, standard surface-mount fastener patterns apply — consult the installation sheet for hole spacing before pre-drilling. Pairs naturally with rack enclosures and cable management systems on enterprise AV, security, and structured cabling deployments where module-based data outlets are part of the design.

If your project requires multi-port data terminations at a single location, Middle Atlantic offers multi-module raceway boxes in the same product family — the PDB1CMFW is the right call only when a single-port station is the spec. For projects requiring a broader rack accessories solution including power distribution, cable managers, and blanks, the Middle Atlantic line covers those adjacencies as well.

Frequently Asked Questions

Q: What module does the PDB1CMFW accept?

A: The PDB1CMFW accepts one front-loaded, downward-facing Pass and Seymour CM module. It is not designed for other module formats or generic keystone inserts.

Q: Can the PDB1CMFW be used without Eclipse Raceway?

A: Yes. The PDB1CMFW supports standalone surface mount applications independent of Eclipse Raceway — it can be mounted directly to a wall, column, or any flat surface using standard fasteners.

Q: What conduit size does the knockout on the PDB1CMFW support?

A: The PDB1CMFW has a 1/2-inch trade size knockout, compatible with standard EMT and flexible conduit fittings used in commercial structured cabling installations.

Q: Is the PDB1CMFW flush-mount or surface-mount?

A: Surface mount only. The PDB1CMFW is designed to sit on the surface of a wall or raceway — it does not require a flush rough-in cut. This makes it well-suited for finished surfaces and retrofit applications.

Q: Can the Pass and Seymour module be replaced without removing the PDB1CMFW from the wall?

A: Yes. The front-loaded design allows the module to be seated and removed from the front face of the box, so moves, adds, and changes can be made without unmounting the box.

James Everett

The PDB1CMFW is a focused solution — it does one thing, a single front-loaded downward-facing Pass and Seymour CM module termination in a surface-mount box, and it does it in a way that fits cleanly into both Eclipse Raceway runs and standalone station deployments. On jobs where the cable management spec is already built around Middle Atlantic raceway, this box eliminates the improvised solutions that create callbacks down the line.

Technical Highlights:

• Surface Mount Design: No rough-in required — the box mounts directly to finished surfaces, which matters on retrofit and tenant improvement projects where cutting into walls adds scope and schedule risk.
• 1/2-Inch Trade Size Knockout: Standard conduit sizing means no special fittings — your existing EMT stock fits, conduit runs stay continuous, and the installation stays NEC-compliant without sourcing custom hardware.
• Front-Load Module Access: Module replacement from the front face means MAC work on a live installation doesn't require unbolting the box — a real time saver when managing data outlet changes in occupied facilities.

Deployment Considerations:

• Verify that your termination spec calls for the Pass and Seymour CM module in the downward-facing front-load orientation — the PDB1CMFW is not a universal keystone box, and ordering against a different module format means a return trip.
• For multi-port data stations, this is not the right box — the PDB1CMFW is a single-module enclosure. Multi-port requirements in the same Middle Atlantic family will need a different model from that line.

The PDB1CMFW fits best on enterprise AV and security installations where Eclipse Raceway is already spec'd and data outlet stations are single-port by design — conference rooms, corridor stations, and equipment room patch points where clean cable management is a deliverable, not an afterthought.
