Panduit FRRASC4LBL FiberRunner Angled Fitting Cover

The Panduit FRRASC4LBL is an angled fitting cover engineered for 4×4 FiberRunner cable routing systems in data centers and telecommunications central offices. This black polycarbonate/ABS cover protects fiber transitions at directional changes while maintaining the clean, professional appearance required in mission-critical infrastructure. UL Listed to 2024A and compliant with Telcordia GR-63-CORE Level 3 seismic and environmental tests, it meets the demanding standards for carrier-grade installations where fiber protection and accessibility cannot be compromised.

RoHS compliant for global deployment and environmental responsibility

Fiber cable routing in data centers and central offices demands protection at every transition point—especially at directional changes where bend radius violations and physical damage risks peak. The FRRASC4LBL angled fitting cover snaps into place over FiberRunner 4×4 pathway corners and angles, enclosing fiber bundles during vertical-to-horizontal transitions, row-to-row runs, and ladder-to-conduit handoffs. The polycarbonate/ABS blend provides impact resistance against accidental contact during maintenance while remaining lightweight enough to remove and reinstall repeatedly without fatigue or cracking. Unlike generic raceway covers, this component is dimensioned to the 4×4 FiberRunner cross-section, eliminating gaps that expose cables or create snag points for technician clothing and tools.

UL 2024A listing confirms the assembly meets flammability, mechanical strength, and fiber protection requirements for permanently installed optical fiber routing systems. Telcordia GR-63-CORE Level 3 compliance proves the cover withstands the thermal cycling, vibration, and seismic loads defined for Network Equipment Building Systems—critical for installations in Seismic Zones 3 and 4 or any facility where operational continuity during environmental stress is non-negotiable. The 2.15-inch installed height keeps overhead clearance minimal in tight plenum spaces and under raised floors, while the 9.14-inch length spans standard FiberRunner segment joints without requiring custom cuts or field modifications.

This cover ships individually packaged, with cartons of five units available for multi-aisle deployments or phased buildouts. Installers working on backbone fiber routes between equipment rows, cross-connects in telco COs, or vertically routed fiber risers will find the snap-on design allows one-handed installation and tool-free removal for adds-moves-changes—essential when working from ladders or in confined overhead pathways. For facilities deploying Panduit's FiberRunner 4×4 system as the structured fiber backbone, the FRRASC4LBL angled fitting cover ensures every directional transition maintains the same level of protection, accessibility, and code compliance as the straight-run segments.
