Panduit FRFWC12X4W4LBL FiberRunner 4-Way Cross Fitting

The Panduit FRFWC12X4W4LBL creates a horizontal four-way intersection in FiberRunner 12x4 pathway systems, attaching directly to 12x4 channels and fittings while providing two perpendicular 4x4 exits. This polycarbonate/ABS cross fitting is UL 2024A certified for optical cable routing assemblies and tested to Telcordia GR-63-CORE and NEBS Level 3 standards, making it compliant for carrier-grade data center and central office deployments where pathway integrity and seismic performance matter.

This cross fitting solves the layout challenge when you need to branch fiber pathways in two perpendicular directions from a main 12x4 trunk — common in row-to-row connectivity or when feeding distribution frames from overhead runway systems. The 4x4 exits accommodate lower-density branch runs to equipment racks or cross-connect fields without forcing you to oversize the entire pathway. The fitting attaches to FiberRunner 12x4 channels using the system's snap-together or screw-mount hardware (sold separately), maintaining the same tool-free or low-tool installation that makes FiberRunner fast to deploy and reconfigure. The polycarbonate/ABS blend resists impact and provides the rigidity needed to support pathway weight and maintain proper bend radius when cables are dressed through the intersection.

UL 2024A certification covers the entire assembly when used with listed FiberRunner components, which matters in jurisdictions requiring code-compliant cable support systems for mission-critical infrastructure. Telcordia GR-63-CORE and NEBS Level 3 testing validates the fitting's performance under seismic activity, temperature cycling, and vibration — critical for carrier central offices and colocation facilities where uptime requirements are measured in five-nines. The fitting's 21.25" width accommodates the perpendicular intersection geometry while keeping the overall height under 4.25", allowing installation in ceiling spaces with limited plenum depth. RoHS compliance ensures you can specify this component in projects with environmental procurement mandates or European client requirements.

The FRFWC12X4W4LBL integrates into FiberRunner 12x4 pathway systems without adapters or transition pieces, maintaining the system's 12-inch bend radius and supporting the same cable densities as straight runs. Use this cross fitting when your fiber backbone layout requires true four-way routing — not just a tee with a downstream split — to minimize pathway congestion and maintain organized cable dressing at high-traffic intersections.
