Middle Atlantic DS4000 External Elbow DES - DS4018-DG

Middle Atlantic DS4018-DG DS4000 External Elbow Fitting

Overview

The Middle Atlantic DS4018-DG is a gray external elbow fitting designed for the Middle Atlantic DS4000 raceway and cord cover system. It solves a common installation problem: routing cable runs around outside corners without breaking the continuity of the raceway enclosure. Instead of cutting, bending, or improvising with raw cable exposed at a direction change, the DS4018-DG maintains a clean, finished transition — the kind of detail that matters in customer-facing lobbies, conference rooms, and AV/security infrastructure installs where open wiring isn't acceptable. The DS4018-DG is TAA Compliant, making it a valid component in government, federal, and public-sector deployments subject to Trade Agreements Act procurement requirements. The gray finish matches the DS4000 series standard color palette for a consistent installed appearance.

Compatibility

The DS4018-DG is purpose-built for the Middle Atlantic DS4000 raceway series. It is an external elbow fitting, meaning it handles outside-corner transitions in the DS4000 line — confirm you need an external (convex) corner piece rather than an internal elbow before ordering, as both elbow variants exist in the DS4000 family and are not interchangeable. Verify your existing raceway color is gray before ordering; Middle Atlantic offers the DS4000 line in multiple finishes, and mismatched components are visually obvious in finished installations. This fitting is not compatible with other Middle Atlantic raceway families (e.g., DS3000 or DS5000 series) or third-party cord cover systems.

Installation Notes

Install this fitting at any outside-corner transition point along a DS4000 raceway run. No tools beyond standard hand tools are required for assembly. Ensure the raceway channel is fully seated and aligned before securing the elbow — gaps at the joint are the most common installation issue with elbow fittings and affect both aesthetics and cable protection. For structured cabling and AV infrastructure projects requiring TAA-compliant components throughout, confirm all raceway sections and fittings in the run carry TAA status.
