Middle Atlantic NM Fbrrdy FLT Elbw 5400WH - 5411FO-WH

Middle Atlantic 5411FO-WH Non-Metallic Flat Elbow Fitting

Overview

The Middle Atlantic 5411FO-WH is a radiused, full-capacity flat elbow fitting from the 5400-series non-metallic raceway line. At 7.8 in (19.8 cm) wide and 1.8 in (4.6 cm) tall, this white fitting is designed to route cable runs through 90-degree horizontal direction changes without kinking conductors or forcing sharp bends that degrade wire insulation over time. If you're running structured cabling, low-voltage security wiring, or AV distribution cable along walls and need a clean corner transition, the 5411FO-WH handles that turn while keeping the installation looking finished and code-compliant. For integrators building out raceway and cord cover systems, this fitting slots directly into the Middle Atlantic non-metallic raceway family — meaning you're not mixing components from different manufacturers or improvising transitions at corners.

Key Features

• 7.8 in (19.8 cm) width: Full-capacity profile accommodates high-density cable fills — useful when running multiple home-run cables through a single raceway rather than splitting across multiple smaller ducts.
• Radiused flat elbow geometry: The curved interior radius guides cables through the 90-degree turn gradually, reducing stress on insulation jackets and avoiding the conductor damage that tight-radius fittings cause on larger-gauge wire.
• 1.8 in (4.6 cm) height profile: Low-profile form factor keeps the fitting from protruding significantly off wall surfaces, which matters in finished office, retail, or lobby environments where aesthetics affect client acceptance of the installation.
• White finish (5411FO-WH): Matches white-painted drywall and drop-ceiling grid environments without requiring field painting — the 5411FO-WH (often searched as 5411FO WH) ships ready to install in standard commercial interiors.
• TAA Compliant: Meets Trade Agreements Act requirements, making it eligible for federal, state, and government-funded projects where TAA compliance is a procurement condition — a hard requirement on many GSA and education contracts.
• Non-metallic construction: Eliminates grounding concerns at the fitting level and avoids corrosion in humid environments like mechanical rooms or exterior-adjacent wall chases where metal raceway components can degrade over time.

Integration and Compatibility

The 5411FO-WH is engineered for the 5400-series non-metallic raceway system from Middle Atlantic. Confirm your existing straight raceway sections and covers are from the 5400-series before ordering — mixing series within a single run produces mismatched clip profiles and cover gaps. This fitting pairs with compatible cord cover and raceway accessories including couplers, end caps, and reducer fittings in the same line. For larger security or AV installations requiring structured cable management across multiple rooms or floors, specify the full 5400-series component set at the design stage to ensure consistent fit throughout.

Frequently Asked Questions

Q: Is the Middle Atlantic 5411FO-WH TAA compliant?

A: Yes. The 5411FO-WH is TAA compliant, making it eligible for use on federal and government-contract projects subject to Trade Agreements Act sourcing requirements.

Q: What raceway series does the 5411FO-WH fit?

A: The 5411FO-WH is part of Middle Atlantic's 5400-series non-metallic radiused full-capacity raceway line. Verify your straight sections and accessories are from the same 5400 series before ordering to ensure compatible clip and cover profiles.

Q: What are the dimensions of the 5411FO-WH?

A: The fitting measures 7.8 in (19.8 cm) wide and 1.8 in (4.6 cm) tall.

Q: What color is the 5411FO-WH?

A: White. It is designed for installation in standard commercial interiors with white walls or ceiling grids and ships ready to install without field painting.

Q: Is this fitting metallic or non-metallic?

A: Non-metallic. This eliminates grounding concerns at the fitting and reduces corrosion risk in humid or moisture-adjacent environments.

Ted Perry

The 5411FO-WH is a straightforward component, but the spec that matters most on a government or education job is TAA compliance — and Middle Atlantic confirms it for this fitting. When your project specs call for TAA-compliant cable management throughout, specifying the 5411FO-WH at corners keeps your entire raceway run compliant without sourcing exceptions or substitution paperwork.

Technical Highlights:

• 7.8 in width: Full-capacity profile supports high cable fill — spec this when consolidating multiple security or AV home runs through a single raceway rather than running parallel smaller ducts that create a cluttered wall installation.
• Radiused elbow geometry: Gradual turn radius protects larger-gauge conductors and multi-conductor cables that fail prematurely when forced through sharp 90-degree bends — a real-world cause of intermittent signal issues that are difficult to trace post-installation.
• TAA Compliant: Verified for the 5411FO-WH — directly addresses the procurement gate on GSA schedules and state-funded construction projects without requiring a waiver.

Deployment Considerations:

• Confirm all other components in your 5400-series run — straight sections, couplers, end caps — are from the same product family before ordering; the 5400 series uses a specific clip and cover profile that does not interoperate with adjacent series.
• The 1.8 in height profile is low but non-flush; in finished environments with tight clearance between wall surface and furniture or fixtures, verify physical clearance before finalizing raceway routing.

Best fit for commercial security and AV integrators running structured low-voltage cable through finished office, education, or government facility interiors where TAA compliance is a contract requirement and a clean white finish is expected without field modification.
