Panduit FRSPJ2X2LBL FiberRunner Spill-Over Junction
The Panduit FRSPJ2X2LBL is a FiberRunner spill-over junction designed for managing fiber transitions in high-density data center and telco central office pathways. This polycarbonate/ABS junction enables controlled routing where fiber cables exit the main FiberRunner channel system - preventing bend-radius violations and cable damage at critical junction points. Compatible with 2x2, 4x4, 6x4, 12x4, and 24x4 FiberRunner systems, it provides UL 2024-listed protection for fiber routing assemblies while meeting Telcordia GR-63-CORE Level 3 requirements for network equipment building systems.
Key Features

- UL Listed to 2024 Optical Fiber Cable Routing Assemblies standard
- Telcordia GR-63-CORE Level 3 compliant for NEBS installations
- 5.61" height × 8.78" length × 4.9" width footprint for compact junction design
- RoHS compliant low-smoke material composition
- Black finish for professional data center aesthetics
The FRSPJ2X2LBL junction is molded from a polycarbonate/ABS blend that delivers the impact resistance of polycarbonate with the surface hardness and dimensional stability of ABS - critical for installations where fiber pathways cross mechanical equipment zones or high-traffic ladder rack corridors. The 5.61-inch height and 8.78-inch length provide sufficient internal volume for managing fiber slack loops without forcing tight bends, while the 4.9-inch width maintains compatibility with standard 2-inch to 4-inch pathway widths. UL 2024 listing confirms the assembly meets flammability, mechanical load, and fiber protection requirements for optical fiber cable routing systems. Telcordia GR-63-CORE Level 3 compliance verifies the junction passes earthquake simulation, thermal cycling, and humidity exposure tests required for NEBS (Network Equipment Building System) installations in carrier-grade telecom facilities.
In data center fiber backbone deployments, spill-over junctions solve the problem of transitioning fiber from horizontal overhead FiberRunner pathways down to vertical rack-mounted patch panels without creating pinch points or minimum-bend-radius violations. The FRSPJ2X2LBL is typically installed where a 2x2 or larger FiberRunner channel meets a vertical drop to equipment racks - the junction's angled exit geometry guides fiber bundles through the 90-degree transition while maintaining separation between cable groups. For telco central offices deploying DWDM or high-fiber-count OSP cables, these junctions provide code-compliant routing at splice enclosure interfaces where hundreds of individual fibers must be organized from trunk pathways into work area channels. The black finish maintains the professional appearance expected in customer-facing data halls and carrier hotels.
The FRSPJ2X2LBL's multi-size compatibility (2x2 through 24x4 FiberRunner systems) reduces inventory SKU count for integrators managing mixed pathway installations - one junction design serves five different FiberRunner channel sizes. Telcordia GR-63-CORE Level 3 certification makes this junction eligible for Tier III/IV data center projects and carrier central office builds where NEBS compliance is a contract requirement, while UL 2024 listing satisfies NEC Article 770 requirements for optical fiber cable pathway assemblies in inspected installations.
