Middle Atlantic PDB4TJFW 4-Port TracJack Large DA Surface Mount Box
The Middle Atlantic PDB4TJFW is a non-metallic, four-port surface mount enclosure designed to terminate TracJack connectors at the edge of structured cable runs in rack and raceway installations. At 3.75" H x 5" W x 1.44" D, it fits flush against walls, equipment frames, or within cable management raceway runs without adding unnecessary bulk. If you're deploying Eclipse Raceway systems or consolidating multi-port terminations at a work area or equipment station, this box is the clean finish line for that run.
Key Features
- Four Front-Loaded TracJack Ports: accepts up to four TracJack inserts loaded from the front, so you can terminate Cat6, fiber, AV, or mixed-media connections in a single enclosure — useful when a single drop point needs to serve multiple device types simultaneously.
- Eclipse Raceway Compatibility: engineered to mate directly with Middle Atlantic's Eclipse Raceway system, which means rack accessories and raceway components connect without adapters or custom fabrication — keeps the installation clean and code-compliant.
- Non-Metallic Construction: the fog-white polymer body eliminates ground loop risk at termination points and resists corrosion in humid or coastal environments — relevant in server rooms with condensation risk or outdoor-adjacent pathways.
- Surface Mount and Rack Mount Flexibility: the dual-mount design lets you attach the PDB4TJFW directly to a wall stud, back-box, or rack surface — no single-mode constraint means one SKU covers multiple termination scenarios in the same project.
- Two 1/2" Trade Size Knockouts: pre-scored knockouts accept standard 1/2" conduit or raceway fittings, so field routing into the box follows the same hardware already on the truck — no special entry fittings needed.
- Compact Footprint (3.75" x 5" x 1.44"): shallow 1.44" depth keeps the box from protruding into walkways or equipment clearances — important in tight server rooms, AV closets, or finished wall surfaces where projection is a concern.
- Fog White Finish: matches standard commercial wall plates and raceway finish colors, which matters in customer-facing spaces like lobbies, conference rooms, and retail environments where exposed infrastructure needs to look intentional.
Integration & Compatibility
The PDB4TJFW is part of the broader Middle Atlantic cable management ecosystem. TracJack inserts are sold separately and support a wide range of termination types — data, voice, coax, fiber, and AV formats — allowing the same box to serve different infrastructure roles depending on which inserts are loaded. Eclipse Raceway compatibility means the box integrates directly into surface-mounted raceway runs without transition fittings. For projects using PoE switches and structured cabling, this enclosure works as the termination point for drops feeding IP cameras, access control readers, or VoIP phones at the work area. Pair with a patch panel at the head end for a fully documented, traceable horizontal run.
Frequently Asked Questions
Q: What type of connectors does the PDB4TJFW accept?
A: The PDB4TJFW accepts four TracJack connectors, loaded from the front. TracJack inserts are available in various media types including data, voice, coax, and AV formats — inserts are purchased separately.
Q: Is the PDB4TJFW compatible with Eclipse Raceway systems?
A: Yes. The PDB4TJFW is specifically designed for Eclipse Raceway compatibility, allowing direct integration into Middle Atlantic surface-mounted raceway runs without additional adapters.
Q: Can the PDB4TJFW be wall-mounted or is it rack-only?
A: Both. The PDB4TJFW supports surface mount and rack mount installation, giving installers flexibility across different termination environments in the same project.
Q: What conduit size do the knockouts on the PDB4TJFW accept?
A: The box includes two 1/2" trade size knockouts, compatible with standard 1/2" conduit fittings and raceway connectors.
Q: What are the physical dimensions of the PDB4TJFW?
A: The PDB4TJFW measures 3.75" H x 5" W x 1.44" D. The shallow 1.44" depth is intentional for flush surface installations where protrusion depth is a constraint.
The detail I keep coming back to on the PDB4TJFW is the 1.44" depth. That number matters the moment you're installing in a finished office corridor or conference room where anything deeper than 1.5" starts catching shoulders and triggering facilities complaints. This box is purpose-built to disappear into a surface run cleanly.
Technical Highlights:
- Front-Loaded 4-Port Design: all four TracJack inserts load from the front face, which means the box can be fully mounted and wired before inserts are populated — useful when AV and data inserts arrive on different schedules or when the media mix changes during the project.
- Eclipse Raceway Direct Fit: no transition fittings between the raceway run and the termination box — this is a real labor savings on multi-drop installations where every fitting is another connection point to troubleshoot.
- Non-Metallic Body: eliminates ground loop risk at the termination point, which matters in mixed-signal AV environments where a metallic box tied to building ground can introduce hum into audio or interference into low-voltage data runs.
Deployment Considerations:
- TracJack inserts are not included — confirm insert media types (Cat6, coax, fiber, AV) before ordering to avoid a return trip to the site.
- The two 1/2" knockouts cover most raceway entry scenarios, but if your run uses larger conduit, plan for a reducer fitting — the box has no larger knockout options based on the spec evidence available.
Best fit for conference room and lobby AV/data termination points on Eclipse Raceway deployments where a clean fog-white finish, mixed-media flexibility, and shallow projection are all required simultaneously — not a general-purpose single-media drop box.
