Panduit FRT4X4LBL FiberRunner Horizontal Tee Fitting
The Panduit FRT4X4LBL creates 90-degree horizontal branch points in FiberRunner 4x4 structured fiber pathways. Designed for data center and central office installations where backbone runs split to distribution zones, this tee fitting maintains minimum bend radius requirements while supporting multiple downstream transition options—overflow fittings, vertical tees with three-way trumpets, corrugated conduit adapters, and continuous FiberRunner sections. Polycarbonate/ABS construction meets UL 2024A certification for optical cable routing assemblies and Telcordia GR-63-CORE seismic/environmental standards. Ships as a single unit in black finish; carton quantity is five for volume deployments.

The FRT4X4LBL forms horizontal intersections where your main 4x4 FiberRunner pathway needs to feed a perpendicular zone—rack row splits, cross-aisle distribution, or equipment room branches. The fitting's internal radius geometry keeps bend radius within ANSI/TIA-568 and manufacturer minimums for both single-mode and multimode trunks. Downstream from each outlet you can snap on FiberRunner overflow fittings for additional pathways, mount a vertical tee with trumpet insert for drop cables, transition to flexible corrugated conduit for final equipment connections, or continue with straight FiberRunner sections. The 12.95" overall width spans two 4x4 pathway widths plus the branch leg; plan 9.22" of longitudinal run length for the fitting body. Polycarbonate/ABS blend provides structural rigidity under cable load while resisting impact from ladder contact or equipment moves. All corners and edges are radiused to prevent jacket abrasion on cables passing through the intersection.
UL 2024A certification confirms the FRT4X4LBL as part of a complete optical cable routing assembly—critical for installations under NFPA 70 (NEC) Article 770 or jurisdictions requiring listed pathway components for fiber. Telcordia GR-63-CORE testing validates performance under Zone 4 seismic events, temperature cycling (-40°C to +65°C), and humidity exposure common in central offices and carrier hotels. NEBS Level 3 compliance is a contract requirement for many service provider builds and ensures the fitting won't degrade signal integrity or physical protection under the environmental extremes those facilities encounter. Black finish maintains visual consistency across the FiberRunner system and reduces glare in overhead installations.
The FRT4X4LBL's strength is routing versatility at horizontal branch points—you're not locked into a single downstream pathway type. In a data center spine-and-leaf deployment, use the horizontal tee where your backbone FiberRunner run branches to feed a leaf switch row, then choose overflow fittings for continued overhead routing or vertical tees with trumpets for drop cables into the rack row. In a central office, branch from the main cable highway to equipment bays using the tee, then transition to corrugated conduit for final connections to ODF frames. This flexibility eliminates the need to stock multiple fitting types for different branch scenarios; the FRT4X4LBL handles the intersection, and you select the downstream component based on the specific pathway requirement.
