Panduit FRFWC6X4LBL FiberRunner 4-Way Cross Fitting, 6x4

Overview

The Panduit FRFWC6X4LBL is a four-way horizontal cross fitting for the FiberRunner™ 6x4 cable routing system, purpose-built for data centers and central telecommunications offices where fiber pathways intersect at right angles. It attaches directly to 6x4 FiberRunner channels and/or fittings, creating a clean four-way junction with two 6x4 outputs on each axis — eliminating improvised bends or exposed fiber runs at cable intersections. If your raised-floor or overhead tray layout calls for a clean 90° crossover rather than two back-to-back tees, this is the correct fitting.

At 14.5 inches overall length and 4.22 inches height (107.1 mm), the FRFWC6X4LBL has a known physical footprint you can plan into overhead ladder-tray or below-floor fiber routing grids before you pull wire — no field-fabrication surprises.

Key Features

• Four-way horizontal cross geometry: Delivers two orthogonal 6x4 pathways in a single fitting. On a dense data center floor with bidirectional runs crossing overhead, this eliminates the stacking of multiple smaller fittings and keeps bend radius compliant through the crossing.
• Polycarbonate/ABS construction: The PC/ABS blend balances the rigidity of polycarbonate with the impact resistance of ABS — important in high-traffic data center environments where ladders and equipment carts regularly pass under cable trays. You get dimensional stability without the brittleness of pure polycarbonate.
• RoHS compliance: Restricts hazardous substances in the fitting material, which matters for LEED-certified builds and enterprise sustainability procurement requirements. Verify your project's RoHS documentation requirements before ordering at scale.
• UL-listed optical fiber routing assemblies to 2024A: The UL listing to the 2024A standard means this fitting has been independently verified for use in fiber routing assemblies — not just a self-declared rating. This supports the Authority Having Jurisdiction (AHJ) sign-off process in commercial builds.
• Telcordia GR-63-CORE NEBS Level 3 compliance: NEBS Level 3 is the full seismic and environmental qualification for central office and carrier-grade deployments. If you're installing in a telecom CO or any facility governed by NEBS requirements, this fitting carries the credentials — most generic cable management fittings do not.
• FiberRunner 6x4 system integration: Designed exclusively for the Panduit FiberRunner 6x4 system. The fitting snaps onto channels and other 6x4 fittings without tools in standard configurations — keeping installation time predictable on large-scale structured cabling projects.
• Black finish, carton quantity of 5: Stocked in cartons of five units. On large data center deployments with dozens of cross-points, ordering in carton quantities avoids per-unit premium pricing and keeps spares on-site for moves, adds, and changes.

Integration and Compatibility

The FRFWC6X4LBL is designed for use exclusively within the Panduit FiberRunner 6x4 system. It interfaces directly with FiberRunner 6x4 channels and compatible 6x4 fittings. It is not cross-compatible with FiberRunner 4x4, 2x2, or other channel sizes — verify your installed channel size before ordering. For complete fiber cable management runs, pair this fitting with the appropriate straight channels, 90° elbows, tees, and end caps within the 6x4 family. NEBS Level 3 and UL 2024A listings make this fitting suitable for structured cabling in carrier facilities, enterprise data centers, and central offices where third-party certification is a contract requirement.

Frequently Asked Questions

Q: Is the FRFWC6X4LBL compatible with FiberRunner channels other than 6x4, such as 4x4 or 2x2?

A: No. The FRFWC6X4LBL is designed specifically for the FiberRunner 6x4 system. It is not compatible with 4x4, 2x2, or other FiberRunner channel sizes. Confirm your installed channel dimensions before ordering.

Q: Does the FRFWC6X4LBL meet NEBS Level 3 requirements?

A: Yes. The fitting is compliant with Telcordia GR-63-CORE and Network Equipment Building Systems (NEBS) Level 3 environmental and seismic standards, making it suitable for carrier-grade central office installations.

Q: Is the FRFWC6X4LBL RoHS compliant?

A: Yes. The FRFWC6X4LBL is RoHS compliant, restricting the use of hazardous substances in its construction — relevant for LEED-certified projects and enterprise sustainability requirements.

Q: What is the UL listing for the FRFWC6X4LBL?

A: The fitting is UL-listed for optical fiber routing cable assemblies to the UL 2024A standard, providing independent third-party verification for AHJ approval in commercial installations.

Q: How many units come in a carton?

A: The FRFWC6X4LBL ships with a package quantity of 1 unit and a carton quantity of 5 units.

Marty Allison

When you're laying out FiberRunner 6x4 pathways in a dense data center or carrier CO, the FRFWC6X4LBL is the right call at any orthogonal intersection — the 14.5-inch overall length gives you a known planning dimension, and the four-way cross geometry means you're not stacking tees or improvising at the crossover point. I spec this fitting when the cable plan shows bidirectional runs crossing overhead and bend-radius compliance at the junction is non-negotiable.

Technical Highlights:

• NEBS Level 3 / GR-63-CORE: Full carrier-grade seismic and environmental qualification — most third-party cable management fittings stop at RoHS; this one carries the credentials for central office AHJ sign-off.
• UL 2024A optical fiber routing listing: Independent verification for fiber routing assemblies, not a self-declared rating — supports the permit and inspection process on commercial builds without back-and-forth with the AHJ.
• PC/ABS construction: Polycarbonate rigidity plus ABS impact resistance in a single material — dimensionally stable under the thermal cycling of active data center environments, and it won't crack under incidental contact from equipment moves.

Deployment Considerations:

• This fitting is 6x4 only — double-check your installed FiberRunner channel size before ordering. Mixing with 4x4 or 2x2 channels requires different fittings; there is no adapter within the system.
• Carton quantity is 5 units. On large deployments plan your cross-point count in multiples of 5 to avoid partial-carton waste or a reorder delay mid-installation.

Best fit: carrier central offices and enterprise data centers under NEBS compliance requirements, where fiber pathway intersections need certified fittings and the AHJ will ask for the UL 2024A documentation.
