Panduit FREC12X4LBL FiberRunner 12x4 End Cap
The Panduit FREC12X4LBL end cap provides professional pathway termination for FiberRunner 12x4 channel systems in datacenters and central offices. Molded from polycarbonate/ABS composite, this closure component seals open ends of raceway and fittings to prevent cable snagging, dust ingress, and accidental pulling on exposed fiber or copper trunk bundles. Designed for high-density routing environments where clean pathway closure is required for safety inspections and maintainability audits.
Key Features
- Polycarbonate/ABS construction for impact resistance and dimensional stability across -40°C to +80°C temperature range
- UL certified optical cable routing assemblies to 2024A standard for central office and datacenter installations
- Telcordia GR-63-CORE compliant for seismic and environmental stress testing per carrier-grade specifications
- NEBS Level 3 qualified for network equipment building systems deployment in telecom facilities
- RoHS compliant material composition for international datacenter sustainability requirements
- Precision fit for FiberRunner 12x4 channel profile without need for fasteners or adhesives
- Black finish matches standard FiberRunner pathway color for clean visual integration
The FREC12X4LBL measures 13.79 inches wide by 5.28 inches high with a 0.94-inch profile depth, matching the FiberRunner 12x4 raceway footprint exactly. The polycarbonate/ABS blend provides superior impact resistance compared to pure ABS or PVC alternatives while maintaining flame-retardant properties required for plenum and riser pathway applications. UL certification to 2024A covers the complete optical cable routing assembly when used with matching FiberRunner channel, ensuring compliance with NEC Article 770 for optical fiber cables and raceways. The snap-fit installation design eliminates the need for screws or separate retention hardware—press the end cap into the open channel end until the retention tabs engage, creating a secure closure that can be removed for future pathway modifications without tools.
In datacenter hot-aisle/cold-aisle layouts, FiberRunner 12x4 systems typically run above-rack or under-raised-floor to distribute fiber trunk cables from main distribution areas (MDAs) to intermediate distribution areas (IDAs) and equipment distribution areas (EDAs). The FREC12X4LBL end cap closes pathway terminations at patch panel locations, wall penetrations, and temporary routing dead-ends during phased build-outs. Telcordia GR-63-CORE compliance ensures the pathway system withstands earthquake zone 4 seismic testing, humidity cycling, and temperature excursions common in carrier-grade central offices. NEBS Level 3 qualification extends this to meet the full suite of network equipment building system standards including electromagnetic compatibility, fire resistance, and grounding/bonding requirements. For multi-tenant datacenters pursuing Uptime Institute Tier III or Tier IV certification, UL-listed cable routing systems with proper end closure components are frequently required to meet pathway integrity audits.
Panduit FiberRunner systems are engineered to support bend radius protection for OM3, OM4, and OM5 multimode fiber as well as OS2 single-mode installations, with the 12x4 profile providing 4-inch pathway depth to accommodate pre-terminated trunk assemblies with MTP/MPO connectors and breakout legs. The FREC12X4LBL end cap completes the protected pathway by preventing cable jacket abrasion against sharp raceway edges during installation pulls or subsequent adds/moves/changes. Sold individually with carton quantities of 5 for volume projects, enabling installers to order exact quantities for datacenter builds without excess inventory.
