Panduit FRSPJC46LYL 6x4 Hinged FiberRunner Cover

Panduit FRSPJC46LYL FiberRunner 6x4 Spill-Over Junction Cover

The Panduit FRSPJC46LYL is a snap-on hinged cover engineered to fully enclose 6x4 FiberRunner channel at spill-over junction points. Molded from yellow polycarbonate/ABS blend, this cover works exclusively with the FRSPJ4X4LYL spill-over junction base to create a complete protective enclosure for high-density fiber routing in data centers and telecom central offices. The integrated hinge allows technicians to access cables for moves, adds, and changes without removing the cover entirely—eliminating the risk of dropped hardware in active fiber pathways and reducing MAC cycle time.

Key Features

• Snap-fit attachment to 6x4 FiberRunner channel base—no tools required for installation or access
• Hinged design for cable access without full cover removal during MACs
• Yellow polycarbonate/ABS construction for impact resistance and dimensional stability across temperature extremes
• 15" W x 4.7" H x 6.78" L dimensions provide full enclosure for FRSPJ4X4LYL junction assembly
• UL Listed to 2024 Optical Fiber Cable Routing Assemblies standard
• Telcordia GR-63-CORE Level 3 compliant for earthquake, vibration, and thermal shock resistance
• RoHS compliant for facilities with environmental compliance mandates

The FRSPJC46LYL cover uses a polycarbonate/ABS blend selected for both impact resistance and dimensional stability under the thermal cycling common in data center hot aisle/cold aisle layouts. At 15 inches wide and 4.7 inches high, the cover mates with the 6x4 FiberRunner channel cross-section to create a fully enclosed pathway at spill-over junction points where cable density exceeds the capacity of a single straight run. The snap-lock attachment mechanism secures the cover to the channel base without tools, while the integrated hinge allows the cover to swing open for cable access—technicians can add or remove fibers without fully detaching the cover, which reduces the risk of dropping hardware into active fiber infrastructure and cuts MAC cycle time. Yellow color-coding aligns with Panduit's fiber pathway identification standards for single-mode or multi-mode trunk routing.

Spill-over junctions handle transition and overflow points in horizontal FiberRunner pathways—typically at intersections between MDA (main distribution area) and HDA (horizontal distribution area) fiber routing in enterprise data centers, or at cross-connect points in telecom central offices where cable count exceeds the capacity of a single 4-inch or 6-inch channel run. The FRSPJC46LYL cover prevents cable sag and pinch points at these junctions by maintaining continuous side support through the transition, which is critical for preserving minimum bend radius on OS2 single-mode or OM3/OM4/OM5 multi-mode fiber. When paired with the FRSPJ4X4LYL junction base, this cover completes a UL-listed routing assembly that meets NFPA 70 (National Electrical Code) requirements for fiber cable support hardware in plenum and riser spaces.

UL 2024 listing confirms the FRSPJC46LYL meets flammability, mechanical load, and installation requirements for optical fiber cable routing assemblies—mandatory for AHJ (authority having jurisdiction) approval in commercial and institutional builds. Telcordia GR-63-CORE Level 3 compliance means the assembly has passed earthquake simulation (Zone 4), repetitive shock, vibration, and thermal shock testing—required for central office and headend installations where uptime and pathway integrity are non-negotiable. RoHS compliance eliminates restricted substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE) for facilities with ISO 14001 environmental management systems or state-level e-waste regulations. For integrators running high-density fiber between racks or between buildings and meet points, this cover delivers the physical protection and code compliance needed to pass inspection and maintain pathway integrity through adds and changes.
