Panduit FIDT4X4LBL FiberRunner 2-Port Spillout

The Panduit FIDT4X4LBL is a black polycarbonate/ABS 2-port spillout designed for controlled fiber cable egress from FiberRunner 4x4-inch routing systems. Engineered for high-density data center and telco CO environments, this spillout provides two protected exit points that maintain minimum bend radius requirements while keeping fiber pathways organized at rack interfaces, cabinet transitions, and cross-connect points. The snap-in design integrates with FRVT6X4LYL, FRVT4X4LYL, and FVT4X4YL raceway sections without tools, and the 3.6-inch height accommodates LC, SC, and MPO trunk assemblies in duplex or multi-fiber configurations.

Key Features

• Two 90-degree exit ports for fiber egress from 4x4" FiberRunner raceway
• Polycarbonate/ABS construction resists impact and maintains dimensional stability across -40°C to +65°C operating range
• 4.24" L × 4.23" W × 3.6" H dimensions accommodate multi-fiber trunk cables and breakout assemblies
• Tool-free snap-in mounting to FRVT6X4LYL, FRVT4X4LYL, and FVT4X4YL raceway channels
• Black finish matches standard FiberRunner system aesthetics for clean pathway appearance
• UL Listed to 2024 Optical Fiber Cable Routing Assemblies standard
• Telcordia GR-63-CORE Network Equipment Building Systems Level 3 compliant
• RoHS compliant for European and California installations

Fiber cable transitions from overhead or under-floor raceway to equipment racks present a recurring challenge in structured cabling installations: you need perpendicular egress without violating the 1.5-inch minimum bend radius for single-mode fiber or 1.2-inch radius for multimode, while maintaining pathway containment and preventing cable snagging during MACs. The FIDT4X4LBL addresses this by providing two factory-radiused exit openings sized for 12-fiber to 144-fiber trunk assemblies. The 3.6-inch internal height gives clearance for stacked LC duplex breakout legs or parallel MPO harnesses without compression, and the rounded port edges eliminate abrasion points that can damage cable jackets during pulls or repositioning. The polycarbonate/ABS blend delivers impact resistance superior to PVC while maintaining flexibility for snap-in installation—important when retrofitting live raceway runs where you can't disassemble entire sections to add an exit point.

Compatibility spans the 4x4-inch FiberRunner family: the vertical tee (FRVT6X4LYL and FRVT4X4LYL) and the standard vertical raceway (FVT4X4YL). This covers 90 percent of data center overhead and under-floor fiber routing scenarios, from row-to-rack drops in co-location facilities to fiber distribution from MDA/IDA spaces in enterprise campuses. Installation requires no hardware—locate the desired exit point on the raceway channel, snap the spillout into the mounting slots, and route cables through the ports. The two-port configuration supports split routing (one port to the rack front for compute connections, one port to the rear for storage or management networks) or segregated client/infrastructure pathways in service provider COs. The black finish integrates with standard FiberRunner aesthetics, maintaining the clean industrial look that differentiates structured pathway systems from loose cable bundles zip-tied to ladder rack.

UL Listing to 2024 Optical Fiber Cable Routing Assemblies confirms flammability, mechanical load, and fire-propagation testing. Telcordia GR-63-CORE Level 3 compliance addresses earthquake (Zone 4), temperature cycling, and office vibration resistance—critical for telco CO and co-location deployments where pathway infrastructure must survive the same environmental conditions as the equipment it serves. RoHS compliance covers lead-free material requirements for installations subject to EU Directive 2011/65/EU or California Prop 65 oversight. Panduit ships the FIDT4X4LBL individually packaged (carton quantity 5 units) to support both volume pathway builds and break-fix inventory stocking in maintenance depots.
