Panduit FIV452X2LYL FiberRunner 45-Degree Inner Vertical Angle

The Panduit FIV452X2LYL creates controlled 45-degree upward transitions in FiberRunner 2x2 fiber routing systems, maintaining proper bend radius while changing cable plane in data center overhead pathways. This inner vertical angle component addresses the critical need for structured vertical cable management where fiber runs must transition from horizontal cable tray to vertical riser or equipment rack without exceeding minimum bend radius limits that cause signal loss or fiber damage.

Key Features

• 45-degree inner vertical angle for FiberRunner 2x2 fiber routing systems
• 7.79" width accommodates 2x2 pathway capacity with full cable support through the bend
• Yellow high-visibility color for immediate identification in mixed-infrastructure environments
• Polycarbonate/ABS construction provides impact resistance and dimensional stability across -40°C to 65°C operating range
• NEBS Level 3 compliant for seismic zones and telecommunications central office installations
• UL 2024A listed for fiber optic cable routing assemblies in plenum and riser applications
• Pairs with FOV452X2LYL outer vertical angle to complete the plane-change transition

This inner angle component measures 4.73 inches high, 2.42 inches deep, and 7.79 inches wide, designed specifically for integration with Panduit's FiberRunner 2x2 routing system. The polycarbonate/ABS blend provides the structural rigidity needed to support loaded fiber bundles through the 45-degree transition without sagging or deformation, while the smooth interior prevents cable jacket abrasion during installation and adds/moves/changes. The 45-degree angle is engineered to maintain bend radius above the 1.5-inch minimum for most single-mode and multimode fiber types, critical for preventing attenuation and back-reflection issues in high-speed 40G/100G/400G datacenter links. The yellow color coding matches Panduit's standard for singlemode fiber infrastructure, though the component itself is fiber-type agnostic and equally suitable for multimode OM3/OM4/OM5 deployments.

In raised-floor data center environments, the FIV452X2LYL inner angle is typically deployed at the point where horizontal overhead cable tray must transition down to top-of-rack connections or where under-floor fiber must rise to meet overhead distribution. The component installs via snap-fit connection to adjacent FiberRunner 2x2 straight sections and must be used in conjunction with the FOV452X2LYL outer angle piece to complete the pathway—the inner angle forms the ascending side of the bend while the outer angle closes the exterior, creating a fully enclosed 45-degree transition that prevents cable spillover and maintains pathway aesthetics. Installation requires no tools for the snap-fit connections, though mounting brackets may be needed depending on the support structure. The 2x2 pathway cross-section provides capacity for approximately 144-288 fibers depending on cable type and density, making this suitable for spine-leaf architecture distributions and multi-tenant fiber aggregation points.

Compliance with Telcordia GR-63-CORE and NEBS Level 3 qualifies this component for telecom central office deployments in seismic zones, where cable pathway integrity during earthquake events is a life-safety and service-continuity requirement. UL 2024A listing covers both material flammability and pathway assembly performance, necessary for authority having jurisdiction (AHJ) approval in municipalities that enforce NEC Article 770 fiber optic cable installation standards. The RoHS compliance ensures compatibility with European and California e-waste regulations for organizations with global procurement mandates. Each carton contains five pieces, supporting multi-row data center deployments or providing spares for MACs without requiring a separate procurement cycle.
