Panduit FRH45SC12LYL FiberRunner™ 12x4 Split Fitting Cover
The Panduit FRH45SC12LYL is a split fitting cover engineered for 12x4 FiberRunner™ horizontal pathways in data centers and telecom central offices. This corner-fitting cover creates toolless access points at 90-degree bends, letting you add or remove fiber bundles without disassembling entire raceway runs. The yellow polycarbonate/ABS construction meets LSZH (Low Smoke Zero Halogen) fire-safety requirements while maintaining the impact resistance needed for high-traffic server rows and MDF environments.
Key Features
- Split-hinge design for cable adds/moves/changes without raceway disassembly
- 15.34" × 15.99" footprint covers FiberRunner 12x4 elbow fittings
- Polycarbonate/ABS blend resists impact and UV degradation in 24/7 facilities
- LSZH compound reduces toxic-smoke hazard in enclosed telecom spaces
- UL 2024A certified for optical-cable guidance assemblies
- Telcordia GR-63-CORE and NEBS Level 3 seismic/vibration compliant
- High-visibility yellow for fiber-pathway identification and safety marking
- Snap-fit retention works with existing FiberRunner 12x4 elbows
FiberRunner corner fittings are the highest-congestion points in any fiber backbone — every horizontal-to-vertical transition and aisle turn concentrates dozens or hundreds of LC/MPO trunks in a 16-inch bend radius. Solid one-piece covers force you to unlatch the entire elbow assembly and slide it off the raceway base just to dress in a single breakout cable. The FRH45SC12LYL's split construction opens along a living hinge, exposing the full cable bed while the fitting stays mounted. You dress the new fiber, snap the cover closed, and move on — no fasteners, no pathway interruption, no risk of dropping an elbow onto live equipment below. This becomes critical during after-hours MACs in co-location facilities where you can't take down an entire row to add one customer circuit. The polycarbonate/ABS formulation handles the repeated open/close cycles that kill brittle PVC covers, and the LSZH rating satisfies the fire-marshal and insurance-carrier requirements that now govern most carrier hotels and enterprise data halls.
Panduit's FiberRunner 12x4 system is the de-facto standard for overhead fiber distribution in facilities that segregate copper and fiber on separate ladder/basket-tray layers. The 12-inch width accommodates high-density MTP trunk cables and fanout assemblies without exceeding the 1.5-inch minimum bend radius that kills 200G/400G multimode performance, and the 4-inch depth keeps slack-loop service coils organized above the working layer. The yellow cover color extends the TIA-606-C administration scheme most operators use to mark fiber pathways distinct from power (orange) and copper data (blue). Each FRH45SC12LYL ships individually and integrates with the FRH4X12 horizontal cover and FRV4X12 vertical-riser cover in the same system, so you maintain a consistent split-access architecture from backbone entrance to telecom-room termination. UL 2024A certification and Telcordia GR-63-CORE seismic compliance address the product-selection checkboxes in carrier-class RFPs and the building-permit reviews that now scrutinize cable-support methods in seismic zones C and D.
