Middle Atlantic NM Fiberready Ext. Elbow - 5518FO-WH

Middle Atlantic 5518FO-WH Non-Metallic Fiberready External Elbow Fitting

Overview

The Middle Atlantic 5518FO-WH is a white, non-metallic external elbow fitting engineered for fiber-ready raceway installations. Designed to redirect cable runs at external corners without exceeding minimum bend-radius requirements for fiber optic cabling — the critical constraint that standard elbows ignore and that causes signal loss or physical damage to fiber strands over time. If you're running structured cabling or fiber along a wall perimeter and need to turn a corner while keeping your conduit pathway clean and code-consistent, the 5518FO-WH is the fitting that keeps the run intact. TAA compliance makes it a viable pick for government facilities and federally funded projects that require trade-agreement sourcing verification.

Compatibility

Designed for use with the Middle Atlantic 5500-series non-metallic raceway system — specifically the full-capacity 5500 bend-radius product family. Confirm your base raceway is the 5500 NM series before ordering; this elbow is sized and rated for that channel width and depth profile. Not interchangeable with the 5400-series or metallic raceway fittings. For complete cable management runs, pair with compatible Middle Atlantic 5500-series couplers, mounting clips, and straight sections to maintain a continuous fiber-safe pathway. If you're planning a mixed copper-and-fiber structured cabling deployment, review your cable management planning requirements before selecting elbow type — external versus internal elbow selection depends on whether the corner is convex or concave relative to your cable path.
