Panduit FRVT4X4LYL FiberRunner 4x4 Vertical Tee

The Panduit FRVT4X4LYL forms a 90-degree vertical transition from horizontal fiber routing pathways in data centers and central telecom offices. This 4x4 vertical tee integrates with the FiberRunner modular cable management system to create vertical drops or risers while maintaining bend-radius protection for high-density fiber optic trunk cables. The hinged door provides tool-free access to routed cables during adds, moves, and changes without dismantling the pathway.

Key Features

• 90° vertical tee fitting for FiberRunner 4x4 pathways — connects horizontal runs to vertical risers or drops
• Hinged door design — tool-free access to routed fiber without removing the fitting or adjacent pathway sections
• Polycarbonate/ABS construction — impact-resistant material rated for data center and telecom facility environments
• UL-certified optical cable routing assembly — meets UL 2024 standards through 2024 certification cycle
• Telcordia GR-63-CORE compliant — passes NEBS Level 3 environmental and seismic testing for central office installations
• Yellow high-visibility finish — color-codes fiber routing pathways for faster identification during maintenance

The FRVT4X4LYL accommodates vertical transitions in fiber backbone installations where horizontal cable trays or overhead pathways need to drop to equipment racks or floor-level distribution frames. The 4x4 cross-section maintains consistent cable capacity through the turn, preventing compression or over-bending at the transition point. Polycarbonate/ABS blend construction resists impact from rack moves and provides long-term dimensional stability under thermal cycling. The hinged door snaps closed to secure routed cables but opens without tools when you need to add or reroute fiber trunks — eliminating the need to disconnect adjacent pathway sections or pull cables back through the fitting.

The vertical tee integrates with the full FiberRunner 4x4 system including horizontal channels, elbows, couplers, and wall-mount brackets. Consistent mounting hole patterns and snap-together connections allow you to build complete pathway networks without custom fabrication. The fitting's 8.51" length and 14.5" width provide clearance for the 90-degree turn radius while the 7.3" height maintains low profile above equipment racks. Yellow finish matches the FiberRunner 4x4 color standard for fiber-only pathways, visually separating optical cable routes from copper data or power distribution systems.

This fitting ships RoHS-compliant and carries UL certification for optical cable routing assemblies. Telcordia GR-63-CORE compliance confirms the fitting passes NEBS Level 3 earthquake simulation, temperature cycling, and fire performance tests required for carrier-class central office installations. The hinged-door design reduces the labor cost and service disruption of pathway reconfigurations in live data centers where fiber routes evolve as equipment changes.
