Middle Atlantic 889A-WH NM 800 Series Reducing Connector Fitting

Overview

The Middle Atlantic 889A-WH is a non-metallic reducing connector fitting designed for the 800 series raceway and cord cover system. This white fitting solves a common field problem: cleanly transitioning between raceway runs of different sizes without exposed gaps or mismatched hardware. The 889A-WH keeps cable management installations looking finished while maintaining the structural continuity of the raceway assembly. TAA-compliant construction makes it suitable for government and federally funded projects where trade-agreement requirements apply.

Compatibility

Designed for use with Middle Atlantic 800 series non-metallic raceway and cord cover products. This fitting is specific to the 800 series family — do not attempt to use it with 300, 500, or 700 series raceways, as channel dimensions differ and the connector will not seat correctly. Verify the raceway size designations on your existing run before ordering to confirm the reducing connector direction (larger-to-smaller vs. smaller-to-larger) matches your installation.

Installation Notes

The 889A-WH is finished in white to match standard white 800 series raceway sections. If your installation uses paintable or alternate-color raceway, verify color match before installation — repainting after assembly is possible but adds labor. No tools are typically required for snap-fit raceway fittings in this family; consult the 800 series installation guide for specific assembly sequence if running multiple connector types in the same channel segment.
