Middle Atlantic DS4000 Offset Fitting MAT - DS4075A-BK

Middle Atlantic DS4075A-BK DS4000 Offset Fitting

Overview

The Middle Atlantic DS4075A-BK is a black offset fitting designed for use with the Middle Atlantic DS4000 steel raceway system. Offset fittings solve a specific routing problem on installations where a raceway run must transition between two parallel planes — such as stepping out from a wall surface to clear an obstruction or bridging a height difference between two mounting surfaces. The DS4075A-BK handles this transition while keeping cable management continuous and covered, maintaining the finished appearance expected in commercial AV and security infrastructure deployments. TAA-compliant construction makes it a direct fit for government, federal facility, and public-sector projects with TAA sourcing requirements.

Compatibility

The DS4075A-BK is engineered specifically for the Middle Atlantic DS4000 series steel raceway system. Confirm your installed raceway is DS4000-series before ordering — DS4000 fittings are not interchangeable with other Middle Atlantic raceway families (such as the DS200 or DS500 series) due to differing channel profiles and dimensions. For broader infrastructure planning, this fitting pairs with the full range of cable management components in the DS4000 line, including straight sections, inside/outside corners, and couplers. The black (BK) finish matches black-finished DS4000 raceway sections; do not mix with white or ivory variants in visible runs.

Installation Notes

Install the DS4075A-BK in line with the DS4000 raceway run at the point of offset. Secure per the DS4000 system's standard fastening method. The 75A designation indicates the offset geometry — verify the offset depth and angle match your routing requirement before installation, as Middle Atlantic offers multiple offset fitting configurations within the DS4000 family. No special tooling is specified beyond standard installation hardware used across the DS4000 system.
