Middle Atlantic DS4089-DG DS4000 to 4000 Series Raceway Adapter
Overview
The DS4089-DG is a transition adapter from Middle Atlantic that bridges DS4000 series raceway to legacy 4000 series raceway fittings — solving the compatibility gap that arises when combining components from both product generations in a single cable management run. If you're extending or modifying an existing 4000 series installation using current DS4000 components, the DS4089-DG is the connection point that makes the two systems work together without improvised hardware. The gray finish matches standard DS4000 color conventions. TAA-compliant construction makes it a viable choice for government and federally funded installations subject to procurement regulations.
Compatibility
Designed specifically for Middle Atlantic's Middle Atlantic raceway product lines: connects DS4000 series cable management raceway to 4000 series raceway fittings. Use this adapter wherever a DS4000 raceway run terminates into or continues from 4000 series components — including corners, couplings, and end fittings from the 4000 family. Verify the exact fitting type at both the DS4000 and 4000 series connection points before ordering; Middle Atlantic's raceway families use series-specific locking and joining geometry that is not interchangeable without the correct adapter.
