Panduit FRFWC24X4W12LYL FiberRunner 4-Way Cross Junction
The Panduit FRFWC24X4W12LYL creates horizontal four-way fiber pathway intersections in high-density data centers and telecom central offices. This yellow polycarbonate/ABS cross fitting mounts to 24"×4" FiberRunner channel sections to split a single trunk into two perpendicular 12"×4" branch paths, enabling grid-based overhead fiber distribution without custom fabrication or field bending. At over 24 inches long and 34 inches wide, the assembly handles pathway changes-of-direction where traditional conduit would require multiple elbows, reducers, and junction boxes—reducing install time and eliminating sharp-radius bend risks in OM3/OM4/OS2 trunks.

The FRFWC24X4W12LYL's polycarbonate/ABS blend delivers impact resistance and dimensional stability across the -40°F to +150°F range required by NEBS Level 3 testing. At 4.48 inches tall, the cross maintains full 4-inch internal height through the intersection—critical for preserving minimum bend radius on high-fiber-count MPO trunks and pre-terminated assemblies. The 24.48-inch main-axis length and 34.44-inch cross-axis width are sized to align with standard 24-inch on-center ceiling grid spacing, allowing installers to route fiber perpendicularly between rows without custom supports or offset brackets. Material thickness and ribbing meet UL 2024A's flame-spread and smoke-generation limits for plenum-rated cable pathway, so the assembly can run continuously through air-handling spaces without fire-stop penetrations. Yellow pigment is molded throughout the resin (not a surface coating), maintaining color-coding integrity even after UV exposure in rooftop cross-connects or warehouse staging.
Deploy the FRFWC24X4W12LYL in hyperscale data halls where east-west traffic between server pods requires perpendicular fiber drops from a north-south backbone trunk, or in telecom CO environments where DWDM ring distribution splits into multiple equipment rows. The dual 12"×4" branch outputs reduce total pathway width compared to running two full 24"×4" channels side-by-side, freeing ceiling space for power whips and cable tray. Because the cross is a listed component of the FiberRunner system, it maintains the same fill-capacity and support-spacing specifications as straight channel sections—installers don't need separate engineering calculations for the junction. Mounting to existing 24"×4" FiberRunner channel uses the same snap-together system connectors specified for straight runs, so adding a four-way intersection mid-span doesn't require disassembling upstream pathway. The yellow finish differentiates fiber infrastructure from black steel cable tray and white PVC conduit, reducing the risk of accidental cuts during adds/moves/changes.
The polycarbonate/ABS material system resists the cleaning solvents, cable lubricants, and UV exposure typical in data center and central office environments. Unlike metal cable tray that can develop sharp edges from corrosion or field cuts, the molded construction maintains smooth interior surfaces that won't snag jacket materials during cable pulls. The 4-inch height accommodates stacked layers of trunk cables plus service loops without exceeding the 50% fill ratio required by NEC 770.113 for optical fiber raceways. In seismically active regions, the NEBS Level 3 shake-table qualification confirms the cross won't separate from channel sections during ground motion—critical for maintaining fiber pathway integrity in California, Alaska, and Pacific Northwest installations where telecom infrastructure must remain operational during and after seismic events.
For projects requiring color-coded pathway systems—common in multi-tenant colo facilities, hospital campuses, and university research networks—the yellow FRFWC24X4W12LYL provides instant visual differentiation from power distribution (typically orange or black) and copper data cabling (gray or white). This reduces troubleshooting time when tracing circuits and prevents maintenance crews from accidentally disturbing fiber trunks while working on adjacent systems. The RoHS compliance and material declarations support LEED v4 MR Credit requirements for environmental product declarations, helping projects earn points toward Gold or Platinum certification. Installation labor is straightforward: position the cross at the intersection point, snap the side flanges into the mating channel sections, and secure with FiberRunner system connectors—no drilling, tapping, or bonding required. The single-piece molded design eliminates the multi-part assemblies and loose hardware common in field-fabricated solutions, reducing both install time and the risk of dropped components in active data halls.
Telcordia GR-63-CORE and NEBS Level 3 qualification means the FRFWC24X4W12LYL has passed earthquake simulation (Zone 4 seismic), flame propagation (NFPA 262 plenum test), and 72-hour elevated-temperature soak tests—compliance mandated by Verizon, AT&T, and other carriers for central-office installations but increasingly adopted by enterprise data centers pursuing five-nines uptime. UL 2024A listing under the fiber cable raceway standard confirms the assembly won't contribute to fire spread or generate corrosive smoke, protecting both fiber assets and the personnel evacuating the space. For projects requiring third-party verification of cable support systems—common in financial trading floors, healthcare imaging centers, and government secure facilities—the FRFWC24X4W12LYL's test reports and listing marks provide the documentation AHJs expect during plan review and final inspection.
