Panduit FREC6X4LBL FiberRunner 6x4 End Cap

The Panduit FREC6X4LBL closes open ends of FiberRunner 6x4 channel and fittings, preventing cable exposure at termination points. Molded from polycarbonate/ABS blend for impact resistance, this end cap maintains pathway protection through transitions and endpoints in high-density fiber installations. UL 2024A certification and Telcordia GR-63-CORE compliance ensure the fitting meets seismic and fire-safety standards for carrier-grade deployments.

Key Features

• Polycarbonate/ABS construction resists impact and maintains dimensional stability across -40°F to 150°F operating range
• Snap-fit installation on FiberRunner 6x4 channel requires no tools or fasteners
• UL 2024A certification for optical fiber cable routing assemblies ensures code compliance in commercial installations
• Telcordia GR-63-CORE Level 3 qualification for earthquake Zone 4 seismic resistance in central office environments
• Black finish matches standard FiberRunner pathway components for consistent aesthetics across structured cabling systems

The FREC6X4LBL addresses a recurring problem in overhead fiber deployments: unfinished channel ends create snag points during cable pulls and leave pathways open to dust infiltration. The snap-lock design grips the channel's internal rib structure — installers align the cap with the 6.92-inch width and press until the retention tabs engage. The 0.75-inch depth provides full coverage of cut edges while maintaining the 4.63-inch profile height of the assembled pathway. Polycarbonate/ABS blend delivers superior impact resistance compared to PVC alternatives, critical in high-traffic plenum spaces where ladder contact or dropped tools are common. The material is self-extinguishing (V-0 rated) and RoHS compliant, meeting both fire-safety and environmental directives for equipment installed in return-air spaces.

Data center and central office deployments require end caps at riser terminations, branch-offs to equipment rows, and temporary pathway ends during phased buildouts. The FREC6X4LBL works across the full FiberRunner 6x4 ecosystem: straight sections, outside vertical elbows, tees, and cross fittings all share the same end-cap interface. For moves/adds/changes, the friction-fit design allows removal and repositioning without damaging the channel — simply flex the cap outward and pull. In seismic zones, the cap's retention force has been validated to withstand the shake-table profiles defined in GR-63-CORE Zone 4 testing (2.5g peak acceleration), preventing pathway separation during seismic events. The 5-piece carton quantity aligns with typical FiberRunner bundles: a 10-foot channel kit with four elbows generates eight open ends, covered by two cartons.

UL 2024A listing confirms the assembled pathway (channel + fittings + end caps) maintains a continuous 2-hour fire rating when installed per the manufacturer's guidelines, a requirement for horizontal pathways in telecommunications rooms and interbuilding tunnels. Telcordia GR-63-CORE compliance extends beyond seismic to include office vibration, airborne contaminants, and temperature cycling — the three environmental stressors that degrade plastic fittings in 24/7 carrier facilities. Unlike generic end caps sold by cable-tray vendors, the FREC6X4LBL is dimensionally matched to Panduit's extruded channel profile, ensuring the cap sits flush without gaps that could catch fiber jackets during installation or create radio-frequency leakage paths in shielded pathway designs.
