Middle Atlantic NM Four Tracjack Large DA - PDB4TJWH

Middle Atlantic PDB4TJWH Four-Port TracJack Surface Mount Connector Box

Overview

The Middle Atlantic PDB4TJWH is a four-port TracJack connector box built for structured cabling installations where clean, front-accessible terminations matter. Designed as an elbow box connector fitting, the PDB4TJWH mounts directly to a surface or integrates with Eclipse Raceway, giving installers a tidy transition point between in-wall or raceway runs and patch field connections — without improvised wall plates or exposed slack bundled behind rack gear.

This is the kind of component that separates a professional install from a field-expedient one. Four downward-facing, front-loaded TracJack connectors keep terminations accessible from the front without pulling equipment. Two 1/2" trade-size knockouts let you route conduit or raceway entries cleanly — no field drilling, no guesswork on knockout sizing.

Key Features

• Four Front-Loaded Downward-Facing TracJack Connectors: Front-access termination means you can add, swap, or re-terminate connectors without moving the box or pulling runs — a real labor saver during moves, adds, and changes in active spaces.
• Rack-Ready Surface Mount Format: Mounts directly to a surface or drops into an Eclipse Raceway run, so it fits both standalone wall deployments and integrated raceway builds without requiring a separate adapter or enclosure.
• Two 1/2" Trade-Size Knockouts: Pre-sized for standard 1/2" conduit fittings, eliminating field modification. Run conduit in from two directions or use one entry and one exit — the box accommodates both common configurations.
• Eclipse Raceway Compatibility: Designed to fit natively into Middle Atlantic's Eclipse Raceway system, so the PDB4TJWH becomes an integrated node rather than an afterthought add-on when you're building out a full raceway infrastructure.
• Elbow Box Connector Form Factor: The elbow geometry handles 90-degree transitions between raceway segments or between a raceway run and a wall surface — managing direction changes without sharp cable bends that degrade performance on Cat6 or higher-grade runs.
• Standalone Application Support: Works independently of Eclipse Raceway when you need a surface-mount connector station in a location that doesn't connect to a full raceway run — conference rooms, server closets, or equipment rooms with spot cable management needs.

Integration & Compatibility

The PDB4TJWH is engineered to work within structured cable management systems using standard TracJack connectors. It integrates directly with Eclipse Raceway for coordinated raceway builds and operates as a standalone surface-mount box for discrete deployments. The 1/2" knockout sizing is compatible with standard EMT conduit fittings widely available from electrical supply houses, so there are no proprietary fittings required on the conduit side. If you are planning a larger rack infrastructure build, pairing the PDB4TJWH with compatible raceway sections and patch panels keeps the cable management consistent from end to end. For AV and security integrators following a structured cable management strategy, this box provides a defined termination point that survives multiple MAC cycles without degrading the raceway aesthetics.

Frequently Asked Questions

Q: Can the PDB4TJWH be used without the Eclipse Raceway system?

A: Yes. The PDB4TJWH supports standalone surface-mount installation independent of Eclipse Raceway. It mounts directly to a wall or surface wherever a discrete connector station is needed.

Q: What conduit size fits the PDB4TJWH knockouts?

A: The two knockouts are sized for 1/2" trade-size conduit fittings — the standard used with 1/2" EMT and flex conduit. No field modification is required.

Q: How many connectors does the PDB4TJWH hold?

A: Four TracJack connectors, loaded from the front and facing downward. All four are accessible without removing or repositioning the box.

Q: Is the PDB4TJWH compatible with Cat6A TracJack inserts?

A: The box is designed for the TracJack connector system. Specific insert compatibility depends on the TracJack keystone module chosen — verify insert dimensions with the TracJack product line before ordering.

Q: What is the form factor of the PDB4TJWH?

A: It is an elbow box connector fitting in a rack-ready surface mount format, intended for 90-degree cable transitions within or alongside Eclipse Raceway runs.

Karl Wilson

The PDB4TJWH earns its place on installs where Eclipse Raceway is the backbone — the elbow box form factor handles direction changes cleanly, and the four downward-facing front-loaded TracJack positions mean you are not fighting access during termination or when a tenant swaps a connection type mid-lease. It is a small box that prevents a lot of rework.

Technical Highlights:

• Four Front-Loaded Connectors: Downward orientation keeps gravity working for you on patch cords and avoids the upward-loop slack that accumulates inside standard horizontal surface boxes over time.
• Two 1/2" Knockouts: Pre-punched at the correct trade size eliminates the most common field mistake — over-sized holes from a step bit — that compromise the box's clean fit against the raceway section.
• Elbow Box Geometry: The 90-degree transition profile is the correct fitting for an Eclipse Raceway corner or wall-exit — using a standard straight box here forces a sharp bend radius on the cable just inside the entry, which matters on Cat6A and higher grades.

Deployment Considerations:

• When integrating into an Eclipse Raceway run, plan the PDB4TJWH position before pulling cable — the elbow geometry fixes the entry angle, so repositioning after the pull is a full re-run, not a slide adjustment.
• The box holds four TracJack inserts but ships without inserts — budget for keystone modules separately and confirm TracJack compatibility with the specific insert series before ordering if mixing connector types (RJ-45, fiber, HDMI).

Best fit: commercial tenant improvement and AV/security rough-in projects where Eclipse Raceway is specified and the GC requires consistent, inspectable cable management at every transition point — the PDB4TJWH keeps the raceway system intact through 90-degree turns without field fabrication.
