Panduit FRT4X4LYL FiberRunner 4x4 Horizontal Tee Fitting

Overview

The Panduit FRT4X4LYL is a 90-degree horizontal tee fitting for the FiberRunner 4x4 cable routing system, designed to branch a horizontal fiber run at a right angle without bending or stressing optical cables. If you're routing fiber through data center trays or central telecommunications offices and need to split off a secondary run — say, tapping off a main trunk to feed a secondary rack row — this is the piece that keeps everything orderly and code-compliant.

Built from polycarbonate/ABS in a high-visibility yellow, the cable management fittings slot directly into the Panduit FiberRunner system for a continuous guided pathway. The yellow colorway isn't decorative — it's a standard identification convention that helps technicians quickly distinguish fiber pathways from copper runs during installs and future maintenance sweeps.

Key Features

• 90° Horizontal Tee Configuration: Branches a horizontal fiber run at a right angle without forcing a field bend. Field-bending fiber at tee points is one of the more common sources of attenuation complaints post-install — using a purpose-made tee fitting eliminates that entirely.
• FiberRunner 4x4 System Compatibility: Designed exclusively for use with the FiberRunner 4x4 system, so the channel dimensions (4-inch by 4-inch) align precisely with adjacent straight sections, bends, and end caps. Mixing incompatible fittings causes channel gaps that violate minimum bend radius requirements.
• Polycarbonate/ABS Construction: The polycarbonate/ABS blend delivers the rigidity you need to support cable weight across a junction point while staying light enough not to strain overhead support structures. This matters in dense fiber environments where accumulated fitting weight adds up across a cable tray run.
• RoHS Compliance: Meets RoHS requirements, which matters for any project with environmental or export controls — common in government facilities, healthcare data centers, and EU-deployed infrastructure.
• UL-Listed Optical Cable Guiding Assemblies (through 2024): UL listing on the optical cable guiding assembly confirms the fitting has been independently tested for its intended function. Specifying UL-listed pathway components is a standard requirement on many commercial and institutional cabling projects.
• Telcordia GR-63-CORE and NEBS Level 3 Compliance: GR-63-CORE and Network Equipment Building Systems (NEBS) Level 3 testing covers seismic, thermal, and physical stress requirements for telecom equipment environments. If you're installing in a carrier central office or any facility that enforces NEBS standards, this fitting meets the bar — most generic cable management fittings do not.
• 12.95-Inch Width / 4.22-Inch Height Footprint: At 12.95 in. wide and 4.22 in. tall (328.9 mm × 107.2 mm), the tee fitting occupies a predictable footprint for overhead routing layout planning. Knowing the exact envelope lets you confirm clearance before installation rather than discovering interference on a ladder.
• High-Visibility Yellow Colorway: Yellow is the conventional fiber identification color in structured cabling environments. Using the color-coded fitting system consistently across a facility makes it significantly easier for technicians — including those unfamiliar with the original install — to trace and work on fiber routes safely.

Integration & Compatibility

The FRT4X4LYL is engineered for the FiberRunner 4x4 system and connects to corresponding straight sections, 90-degree bends, crosses, and end caps within that product family. It is not interchangeable with FiberRunner 2x4 or 6x4 channels — the channel depth and width are specific to the 4x4 series. When laying out a tee in a data center overhead grid, pair this fitting with the correct straight-section lengths and a compatible mounting bracket or support hardware rated for overhead installation at your facility's structural loading requirements. Sold individually (package quantity of 1); carton quantity is 5 units for project-scale ordering.

Frequently Asked Questions

Q: Is the FRT4X4LYL compatible with FiberRunner 2x4 or 6x4 channels?

A: No. The FRT4X4LYL is designed exclusively for the FiberRunner 4x4 system. The channel dimensions are specific to the 4x4 series and are not interchangeable with 2x4 or 6x4 variants. Verify your installed channel size before ordering.

Q: What does the yellow color on the FRT4X4LYL signify?

A: Yellow is a standard color-coding convention in structured cabling to identify fiber optic pathways, distinguishing them from copper cable routes. Using color-matched fittings throughout a facility simplifies future maintenance and troubleshooting.

Q: Does the FRT4X4LYL meet NEBS requirements for telecom central office installations?

A: Yes. The FRT4X4LYL is tested to Telcordia GR-63-CORE and Network Equipment Building Systems (NEBS) Level 3 standards, which cover seismic, thermal, and physical stress criteria required for carrier central office and telecom equipment environments.

Q: Is the FRT4X4LYL RoHS compliant?

A: Yes. The FRT4X4LYL is RoHS compliant, making it suitable for projects with environmental compliance requirements including government, healthcare, and EU-deployed infrastructure.

Q: How many units come per package, and what is the carton quantity?

A: The FRT4X4LYL ships as a single unit per package (package quantity: 1). Carton quantity is 5 units, so project-scale orders can be fulfilled in multiples of 5 from a single carton.

Q: What are the overall dimensions of the FRT4X4LYL?

A: The FRT4X4LYL measures 12.95 inches wide (328.9 mm), 4.22 inches tall (107.2 mm), and 9.22 inches in overall length. Use these dimensions for overhead routing layout planning and clearance verification before installation.
