Middle Atlantic STL Divider 4000 - G4000D

Middle Atlantic G4000D 4000-Series Steel Raceway Divider Fitting

Overview

The Middle Atlantic G4000D is a steel divider fitting designed for the 4000-series raceway and cord-cover system. At 6.13 inches wide, 1.54 inches tall, and just 0.12 inches deep, this fitting slots into structured cable runs to create clean, code-compliant pathway separation — the kind of detail that distinguishes a professional installation from a field-expedient one. TAA compliance means it qualifies for government and federally funded projects where domestic sourcing is a contract requirement.

The G4000D is sourced from Middle Atlantic's 4000-series raceway family, part of the broader Middle Atlantic cable management catalog. If you're specifying a complete surface raceway system for a commercial security or AV installation, this divider fitting pairs with the matching 4000-series base and cover components to maintain a uniform, finished appearance across the run.

Key Features

• 6.13-Inch Width: Matches the 4000-series channel width exactly — no cutting or field modification required. Inconsistent-width dividers create gaps that fail inspection and look unprofessional in exposed installations.
• 1.54-Inch Profile Height: Low-profile form factor sits flush within the raceway channel, keeping the lid seated and the cable run closed. Proud-fitting dividers prevent the cover from seating fully, a common callback on retrofit jobs.
• 0.12-Inch Depth: At roughly 3mm thick, this divider adds separation between cable groups without consuming usable channel fill space — relevant when you're already near the fill-ratio limit on a dense run.
• TAA Compliant: Meets the Trade Agreements Act requirements, making the G4000D eligible for GSA schedule purchases, federal government projects, and DoD installations where TAA compliance is a hard bid requirement — not a preference.
• Steel Construction: Steel provides the structural rigidity needed to maintain cable separation under real-world installation stress — repeated pulls, bundle weight, and occasional impact. Plastic dividers in high-fill runs tend to bow or shift over time.

Integration and Compatibility

The G4000D is purpose-built for the Middle Atlantic 4000-series raceway system. Verify that your base and cover components share the same series designation before ordering — mixing series produces mismatched profiles that won't seat correctly. This fitting is appropriate for low-voltage cable management runs carrying data, security, and AV cabling in commercial environments. It is not rated for high-voltage power separation; consult applicable electrical codes for power-over-raceway requirements.

For complete pathway planning guidance, the structured cabling planning guide covers fill ratios, bend radius, and raceway selection criteria that apply when specifying this type of fitting in a larger system design. Pair this divider with compatible 4000-series raceway fittings to complete inside corners, outside corners, and end caps in a single-family finish.

Frequently Asked Questions

Q: Is the G4000D TAA compliant?

A: Yes. The G4000D carries TAA compliance, making it eligible for federal, GSA, and DoD projects with domestic-sourcing contract requirements.

Q: What raceway series is the G4000D compatible with?

A: The G4000D is part of Middle Atlantic's 4000-series raceway and cord-cover system. It should be used with matching 4000-series base and cover components to ensure a proper fit and finished appearance.

Q: What are the exact dimensions of the G4000D?

A: The G4000D measures 6.13 inches wide, 1.54 inches tall, and 0.12 inches deep (15.6 cm x 3.9 cm x 0.3 cm).

Q: Is the G4000D suitable for separating power and data cables?

A: The G4000D is a low-voltage raceway divider fitting. For power cable separation, consult your local electrical code and the raceway system's listing ratings — this fitting is not independently rated for high-voltage power segregation applications.

Q: What material is the G4000D made from?

A: The G4000D is a steel divider fitting, providing the structural rigidity needed to maintain cable separation in commercial raceway installations.

James Everett

The G4000D is the kind of component that separates a finished installation from a rough one — at 6.13 inches wide and just 0.12 inches deep, this steel divider fits precisely within the 4000-series channel without displacing usable fill space. I spec it on any project where different low-voltage cable types share the same raceway run and the client expects a clean, inspection-ready result.

Technical Highlights:

• TAA Compliance: Qualifies the G4000D for GSA schedule and federal contract work without a waiver — a hard requirement on government security integrations, not optional.
• 0.12-Inch Divider Depth: Adds physical cable separation while consuming only 3mm of channel depth — critical when fill ratios are already tight on multi-cable runs.
• Steel Construction: Maintains separation integrity under installation load; plastic alternatives in high-fill commercial runs tend to shift during cable pulls, requiring rework.

Deployment Considerations:

• Confirm your base and cover carry the same 4000-series designation before ordering — the G4000D will not seat correctly in a different-series channel even if the width appears close.
• This fitting is not independently rated for power cable segregation; if your run includes line-voltage conductors, verify the full raceway assembly's electrical listing and consult local code before using this divider as a power separator.

Best fit for commercial security and AV integrators running structured surface raceway in lobbies, corridors, and server room perimeters where the cable pathway is fully exposed and the finished look is part of the spec — not an afterthought.
