Panduit FRFWC4X4LYL FiberRunner 4x4 Four-Way Cross Fitting
Overview
The Panduit FRFWC4X4LYL is a four-way horizontal cross fitting engineered for the Panduit FiberRunner 4x4 system. It mounts directly onto a 4x4 channel and/or adjacent 4x4 fittings to create a fully integrated horizontal crossover with two 4x4 outlets — the connector you reach for when fiber routing paths need to intersect at a single managed point rather than branch in just one direction. Designed for fiber routing systems in data centers and central telecommunications offices, this fitting keeps bend radius controlled and cable runs organized at every junction.
At 12.95 in. wide × 4.22 in. tall (328.9 mm × 107.2 mm), the FRFWC4X4LYL has the physical footprint to handle cable volume at a 4x4 channel intersection without crowding adjacent fittings. Yellow color-coding follows the FiberRunner visual lane convention, making it immediately identifiable during installation and troubleshooting in dense cable trays.
Key Features
- Four-Way Horizontal Cross Configuration: Routes fiber in four directions from a single fitting — forward/back plus left/right — eliminating the need to stack multiple elbows or tees to achieve the same crossover. In high-density structured cabling installations this directly reduces junction hardware count and simplifies the physical pathway.
- Polycarbonate/ABS Construction: The blend delivers impact resistance from the ABS component and dimensional stability from the polycarbonate — relevant in data center environments where cable trays flex under load changes or thermal cycling. You get a fitting that holds its geometry and doesn't crack during maintenance access.
- UL Listed for Optical Cable Routing Assemblies (to 2024A): The UL certification to the 2024A standard covers optical fiber cable routing assemblies specifically, confirming the fitting meets defined bend-radius and load requirements. This matters when AHJ sign-off is required on structured cabling infrastructure — unlisted hardware can hold up an inspection.
- RoHS Compliant: Meets EU Restriction of Hazardous Substances requirements, which is a procurement prerequisite for enterprise and government data centers with sustainability or import-compliance mandates.
- Telcordia GR-63-CORE and NEBS Level 3 Rated: GR-63-CORE covers Network Equipment Building System physical protection criteria — seismic, thermal, and fire. NEBS Level 3 is the full compliance tier required for carrier-grade and co-location deployments. If the rack room needs to survive a seismic zone 4 event without the cable plant failing, this is the standard to ask for.
- Yellow Color Coding: Consistent with FiberRunner's color-lane system for immediate visual identification in multi-system trays. Reduces mis-routing errors during adds, moves, and changes when multiple fiber systems share the same overhead or underfloor pathway.
- Direct System Integration with FiberRunner 4x4: Designed exclusively for the FiberRunner 4x4 channel family — snaps onto the channel without additional hardware. Cable management fittings that require adapters add failure points; the direct-mount design removes that variable.
- Carton Quantity of 5 (MOQ 5): Sold individually with a minimum order quantity of 5 units per carton, which aligns with installation practice — data center cabling projects rarely need a single cross fitting in isolation. Ordering in multiples reduces per-unit freight impact and ensures spares are on-hand for phased buildouts.
Integration & Compatibility
The FRFWC4X4LYL is specified for use with the Panduit FiberRunner 4x4 system. It attaches directly to 4x4 channel sections and compatible 4x4 fittings — elbows, tees, and end caps within the same family. It is not interchangeable with FiberRunner 2x4, 4x2, or other channel-size variants; confirm channel size before ordering. The fitting integrates without tools into the FiberRunner snap-together architecture, supporting rapid installation in active data center environments where downtime for fitting assembly is not acceptable.
For projects sourcing from structured cabling supply, verify that the FiberRunner 4x4 channel sections and companion fittings (elbows, drops, covers) are on the same purchase order — mixing fitting generations or channel widths creates mismatches at every junction.

Frequently Asked Questions
Q: What channel size is the FRFWC4X4LYL compatible with?
A: The FRFWC4X4LYL is designed specifically for the Panduit FiberRunner 4x4 system. It is not compatible with other FiberRunner channel sizes such as 2x4 or 4x2.
Q: Is the FRFWC4X4LYL RoHS compliant?
A: Yes. The FRFWC4X4LYL is RoHS compliant, making it suitable for enterprise and government procurement requirements that mandate hazardous substance restrictions.
Q: What standards certifications does the FRFWC4X4LYL meet?
A: The FRFWC4X4LYL meets RoHS, is UL listed for optical fiber cable routing assemblies to 2024A, and is rated to Telcordia GR-63-CORE and NEBS Level 3 — the full carrier-grade physical protection tier.
Q: What are the dimensions of the FRFWC4X4LYL?
A: The fitting measures 12.95 in. (328.9 mm) wide and 4.22 in. (107.2 mm) tall.
Q: What is the minimum order quantity for the FRFWC4X4LYL?
A: The carton quantity is 5 units with a minimum order quantity (MOQ) of 5. Each carton contains a single fitting; MOQ5 means you order in multiples of 5.
Q: What material is the FRFWC4X4LYL made from?
A: Polycarbonate/ABS blend — polycarbonate contributes dimensional stability and impact resistance; ABS contributes structural rigidity. Both are appropriate for data center and telecommunications office environments.
The FRFWC4X4LYL is the fitting I spec when a FiberRunner 4x4 pathway needs to intersect rather than just branch. The NEBS Level 3 and Telcordia GR-63-CORE ratings are the detail that separates it from generic tray hardware — those certifications cover seismic, thermal, and fire criteria that co-lo and carrier environments require at every physical layer, including the cable routing fittings themselves, not just the active equipment.
Technical Highlights:
- NEBS Level 3 / GR-63-CORE: Full carrier-grade compliance for seismic zone 4 and fire resistance — not a feature most integrators check on a cross fitting, but it determines whether the installation passes a carrier facility acceptance test.
- UL 2024A Listed: Specifically for optical fiber cable routing assemblies — the relevant UL scope for fiber management infrastructure. Generic cable tray may carry a different UL listing that doesn't cover this use case.
- 12.95 in. × 4.22 in. footprint: Sized for the 4x4 channel's cable volume. At this cross-section, clearance at the junction is adequate for mid-density fiber runs without forced bends at the exit points.
Deployment Considerations:
- Confirm the FiberRunner channel size on-site before ordering. The 4x4 fitting will not mate with 4x2 or 2x4 channel — the snap-together architecture is size-specific, and mismatches show up at installation, not on paper.
- MOQ of 5 means you're committing to a minimum of 5 units per order. For small retrofit jobs with a single intersection, plan the full pathway layout first so the remaining units go onto the same run rather than sitting in a cabinet.
This fitting is the right call for greenfield data center fiber pathway installations or carrier/co-lo buildouts where NEBS compliance is a contractual requirement — it handles the four-way junction cleanly within the FiberRunner system without requiring field fabrication or adapter hardware.
