Middle Atlantic NM Fbrrdy FLT Elbw 5400IV - 5411FO

Middle Atlantic 5411FO Non-Metallic Radiused Flat Elbow Fitting

Overview

The Middle Atlantic 5411FO is a non-metallic, radiused flat elbow fitting designed for the 5400-series full-capacity raceway system. At 7.8 in wide and 1.8 in tall, it provides a direction change for surface-mounted cable runs without sharp bends that stress conductors — a practical necessity wherever a horizontal raceway must turn a corner along a wall or at a baseboard transition. The ivory finish integrates cleanly into commercial interior environments where aesthetics matter alongside function. TAA compliance makes the 5411FO a straightforward fit for government, education, and federal procurement projects subject to the Trade Agreements Act.

Middle Atlantic's raceway and cord cover line is built around consistent profile dimensions, so fittings like this elbow connect directly into straight sections, couplings, and reducers within the cable management category without requiring field modification. If you are planning a full surface-mount cable pathway — common in retrofit security and AV installations where opening walls is not an option — review the cable management planning guide to size the raceway capacity before specifying fittings.

Key Features

• Radiused flat elbow geometry: The curved interior radius guides cables through a directional change without the tight-bend stress of a sharp 90-degree corner — relevant for Cat6, coax, and low-voltage control wiring that can degrade signal integrity under excessive bend radius violations.
• 7.8 in (19.8 cm) width: Matches the full-capacity 5400-series profile, so this fitting does not become the bottleneck in a high-fill cable run. Size your cable fill to the raceway spec, not the fitting.
• 1.8 in (4.6 cm) height: Low-profile form factor keeps the raceway close to the wall surface, reducing trip hazards and maintaining a clean sight line in occupied spaces like lobbies, corridors, and classrooms.
• Non-metallic construction: Eliminates grounding concerns in environments where metallic conduit would require bonding, and resists corrosion in humid or coastal interior applications.
• Ivory color: Matches standard commercial wall finishes — a practical detail that reduces the visual footprint of surface-mount wiring in customer-facing or tenant spaces.
• TAA compliant: Sourced in compliance with the Trade Agreements Act, making the 5411FO eligible for GSA schedules and federal, state, and municipal contracts that require TAA-compliant products. Confirm current TAA status on your solicitation date.

Integration and Compatibility

The 5411FO is designed as a component within the Middle Atlantic 5400-series raceway fitting system. It connects to straight raceway sections, inside and outside corners, couplings, and end caps in the same profile family. When specifying a complete run, confirm that all fittings — including this elbow — share the same series designation to ensure dimensional compatibility. The non-metallic material is suitable for low-voltage data, AV, and security cabling; verify local code requirements if the raceway will carry line-voltage conductors alongside low-voltage runs.

Frequently Asked Questions

Q: Is the Middle Atlantic 5411FO TAA compliant?

A: Yes. The 5411FO is listed as TAA compliant, making it eligible for federal, state, and municipal procurement vehicles that require Trade Agreements Act compliance. Always confirm compliance status at the time of your specific solicitation.

Q: What color is the 5411FO?

A: The 5411FO is ivory, suited to standard commercial interior wall finishes.

Q: What are the dimensions of the 5411FO?

A: The fitting measures 7.8 in (19.8 cm) wide and 1.8 in (4.6 cm) tall, matching the full-capacity 5400-series raceway profile.

Q: Is the 5411FO metallic or non-metallic?

A: Non-metallic. This eliminates the need for grounding/bonding in environments where metallic conduit would require it, and it resists corrosion in humid interior spaces.

Q: Does the 5411FO work with other Middle Atlantic 5400-series fittings?

A: Yes. The 5411FO is part of the 5400-series raceway system and is designed to connect with straight sections, couplings, and other fittings within the same profile family. Confirm series designation for all components before ordering.

Eden Phillips

The 5411FO comes up on retrofit projects where you need a direction change in a surface-mount run and cannot accept the conductor stress of a sharp-cornered fitting — the radiused elbow geometry is the spec that matters here, and the 7.8 in width confirms you are not constricting a full-capacity 5400-series run at the turn.

Technical Highlights:

• Full 7.8 in width: Matched to the 5400-series full-capacity profile — the elbow does not choke fill capacity at the transition point, which is a common failure mode when integrators mix fitting series mid-run.
• 1.8 in low-profile height: Keeps the raceway tight to the wall surface through the turn, which matters in occupied corridors and lobby spaces where a protruding fitting creates both an aesthetic and a liability concern.
• TAA compliance: Verified for the 5411FO SKU — relevant on any government or institutional project running through a GSA schedule or state cooperative contract where every line-item component must clear TAA.

Deployment Considerations:

• Verify all fittings in the run share the 5400-series designation before ordering — dimensional mismatches between series are the most common installation problem on raceway jobs, and they are not caught until the fittings are on site.
• Non-metallic construction is appropriate for low-voltage security, AV, and data cabling; if the installation requires line-voltage conductors in the same raceway, confirm local electrical code permits non-metallic raceway for that wiring type in your jurisdiction.

The 5411FO is the right call on commercial retrofit security and AV installations — corridor camera runs, access control wiring, and AV distribution in occupied tenant spaces — where the raceway must turn a corner cleanly, the wall finish is ivory, and the procurement vehicle requires TAA-compliant components throughout.
