Middle Atlantic 2389 NM Reducing Connector Fitting

Overview

The Middle Atlantic 2389 is a non-metallic reducing connector fitting designed to join two different-sized non-metallic raceway sections at a transition point. The 2389 solves the common field problem of stepping down between raceway channels of mismatched diameters — keeping cable runs clean and enclosed without improvising a gap or leaving conductors exposed at the junction. Finished in ivory, it blends with standard commercial wall and ceiling installations where aesthetics matter alongside function. TAA-compliant, making it eligible for government and federally funded projects with domestic sourcing requirements.

Compatibility

Designed for use within the Middle Atlantic 2300-series non-metallic raceway system. Connects to non-metallic raceway and cord cover runs where a reducer fitting is required between differing channel widths in the 2300 family. Verify channel dimensions on both sides of the intended junction before ordering — this fitting is sized specifically for the 2300-series reducing interface and is not a universal reducer across unrelated raceway lines. If you are routing low-voltage security cabling, confirm that your cable management plan accounts for bend radius at the reducer point, particularly for larger-gauge shielded runs.

Installation Notes

Non-metallic construction means no grounding continuity through the fitting itself — ensure your grounding scheme does not depend on raceway-to-raceway conductivity at this junction. Ivory finish matches the 2300-series standard color; if your installation uses a painted or custom-color raceway, plan for field finishing. No additional tools or adhesives are specified for standard snap or slide installation typical of this raceway family.
