Middle Atlantic NM Fbrdy INT Elbw 5400 IV - 5417FO

Middle Atlantic 5417FO Non-Metallic 5400-Series Radiused Internal Elbow Fitting

Overview

The Middle Atlantic 5417FO is a non-metallic, full-capacity internal elbow fitting designed for use with the 5400-series radiused cable management raceway system. At 5.5 in wide and 4 in tall, this ivory-finished elbow fitting routes cable runs through interior direction changes while maintaining full channel capacity — no derating, no pinch points. TAA compliance makes it a straightforward specification item for government and federal procurement projects where country-of-origin rules apply.

If you are building out a structured cable management run using the 5400-series raceway, the 5417FO is the interior corner transition piece that keeps the system cohesive and code-friendly. Routing cables around internal corners without a purpose-built fitting typically means improvised bends that stress jacket materials and violate minimum bend-radius requirements — particularly relevant for Cat6A and fiber runs. This fitting eliminates that risk by providing a factory-radiused transition matched to the 5400-series channel geometry.

Key Features

• Full-Capacity Internal Elbow Design: The fitting accommodates the full cross-sectional fill of the 5400-series raceway — no reduction in usable cable space at the corner transition. This matters when you are at or near fill capacity on long horizontal runs feeding a rack or panel.
• 5.5 in Width, 4 in Height: Dimensioned to match the 5400-series profile precisely. Mismatched fittings create gaps that expose cable and fail inspection; confirm your raceway width matches before ordering.
• Ivory Color Finish: Matches standard ivory 5400-series raceway components. Maintains visual consistency across the entire run — relevant in finished office or command-center environments where exposed raceway is intentional.
• Non-Metallic Construction: NM-rated, which means no grounding requirements at the fitting level and lighter overall weight compared to metal raceway systems. Useful in environments where weight loading on wall or ceiling mounts is a factor.
• TAA Compliant: Verified TAA-compliant, making the 5417FO eligible for GSA schedule and federal contract procurement without country-of-origin exceptions. Specify this explicitly in your submittal package if the project has TAA requirements.
• Radiused Transition: The factory radius protects cable jacket integrity through the bend — directly relevant for high-strand-count fiber and Cat6A, where exceeding minimum bend radius causes measurable signal degradation or physical jacket damage over time.

Integration and Compatibility

The 5417FO is designed specifically for the Middle Atlantic 5400-series non-metallic raceway system. It is an internal elbow — meaning it routes direction changes on the inside of a run, as opposed to external elbow fittings used at outside corners. Pair with 5400-series straight sections, couplers, and appropriate entry/exit fittings for a complete non-metallic raceway build. Confirm fitting orientation (internal vs. external) before ordering; the two are not interchangeable at a corner.

Frequently Asked Questions

Q: Is the Middle Atlantic 5417FO TAA compliant?

A: Yes. The 5417FO is verified TAA compliant, making it suitable for federal and GSA schedule procurement where country-of-origin requirements apply.

Q: What color is the 5417FO?

A: Ivory. It is designed to match the standard ivory finish of the 5400-series non-metallic raceway system.

Q: What are the dimensions of the 5417FO?

A: The fitting is 5.5 inches wide and 4 inches tall (14 cm x 10.2 cm).

Q: Is the 5417FO an internal or external elbow?

A: Internal. It is designed for inside-corner direction changes within the 5400-series raceway system, not outside-corner transitions.

Q: Does the 5417FO require grounding?

A: No. As a non-metallic fitting, the 5417FO does not require grounding at the fitting level — a practical advantage in installations where bonding continuity through metal raceway would otherwise require additional hardware.

Jerry Tildsen

The Middle Atlantic 5417FO comes up in almost every 5400-series raceway spec I review for government and enterprise AV/security installations. The TAA compliance status is the spec that actually drives the conversation — on federal builds, a single non-compliant fitting can kick the entire raceway assembly off the BOM, and swapping it mid-project is a headache nobody needs. That alone justifies calling this out explicitly in your submittals.

Technical Highlights:

• TAA Compliant: Verified compliant — no country-of-origin exceptions required for GSA schedule or federal procurement. Include the 5417FO part number explicitly in your compliance documentation rather than covering it under a blanket raceway assembly reference.
• Full-Capacity Internal Elbow: Radiused geometry preserves the full channel cross-section through the direction change. If you are running Cat6A or multi-strand fiber at or near fill, this is the spec that prevents a bend-point bottleneck from becoming a call-back.
• Non-Metallic Construction: No grounding continuity requirement at the fitting. On longer raceway runs with multiple elbows, this reduces installation labor meaningfully compared to metallic systems that require bonding jumpers at each fitting.

Deployment Considerations:

• Confirm internal vs. external elbow orientation before ordering — the 5417FO is an internal elbow only. Ordering the wrong fitting type for an outside corner means a return and a schedule delay; both are avoidable with a quick drawing review up front.
• The ivory finish matches standard 5400-series components. If your raceway run uses white or other color variants, verify the color code separately — color mismatch on exposed raceway in a finished space is a punch-list item that always comes up at closeout.

The 5417FO is the right spec for any 5400-series raceway installation on a TAA-required project — federal courthouses, government operations centers, DoD-adjacent facility work — where every component on the BOM needs a confirmed country-of-origin status and a factory-radiused internal corner transition is part of the cable management design.
