Middle Atlantic DS4000 External Elbow MAT - DS4018-BK

Middle Atlantic DS4018-BK DS4000 External Elbow Fitting

Overview

The Middle Atlantic DS4018-BK is an external elbow fitting designed for the Middle Atlantic DS4000 raceway system, directing cable runs at outside corners without breaking the continuity of a managed pathway. If you're routing structured cabling or low-voltage wiring around exterior building corners, wall transitions, or equipment enclosure perimeters, this fitting keeps the run clean, protected, and compliant. The DS4018-BK ships in black to match standard black DS4000 raceway installations.

Compatibility

The DS4018-BK is purpose-built for the Middle Atlantic DS4000 steel raceway series. It mates directly with DS4000-series raceway base and cover components. Verify your DS4000 raceway width and cover profile before ordering — DS4000 fittings are not interchangeable with other Middle Atlantic raceway families such as the DS3500 or DS5000 series. TAA-compliant status makes this fitting eligible for federal, state, and municipal projects with TAA-compliant product requirements.

Installation Notes

Install at external (outside) corners only — this is not an internal elbow. Confirm the wall corner angle matches the fitting geometry before mounting. Pair with compatible DS4000 raceway accessories (couplings, end caps, mounting clips) to complete transitions. No special tools are required beyond standard low-voltage installation kit; secure the raceway base to the wall surface prior to snapping the elbow cover into place.
