Middle Atlantic DS4089-BK DS4000 to 4000 Series Raceway Adapter

Overview

The Middle Atlantic DS4089-BK is an adapter fitting that bridges DS4000 series components to 4000 Series raceway installations. If you're integrating two raceway generations on the same run — or extending an existing 4000 Series installation with newer DS4000 fittings — this adapter eliminates the mismatch at the junction point. The DS4089-BK ships in black to match standard dark raceway deployments. It carries TAA compliance, making it eligible for federal, state, and government-contract installations where Buy American/TAA provisions apply.

Compatibility

Designed for use within the Middle Atlantic raceway line, specifically to connect DS4000 series fittings to 4000 Series raceway fittings. Verify fitting orientation and channel dimensions against your installed cable management raceway before ordering — DS4000 and 4000 Series profiles are distinct and this adapter is the required interface between them. Not intended for use with non-Middle Atlantic raceway systems or dissimilar channel profiles.
