Panduit FRVT12X4LYL FiberRunner 12x4 Vertical Tee Fitting
Overview
The Panduit FRVT12X4LYL is a 90° vertical tee fitting for the FiberRunner 12x4 cable management system — purpose-built for data centers and central telecommunications offices where fiber routing must change planes without stressing cable bend radii. Where horizontal runs need to branch off and drop vertically, this fitting provides the structural transition point, keeping fiber paths organized, protected, and within code-compliant bend radius at the junction. Constructed from a polycarbonate/ABS blend, it delivers the dimensional stability and impact resistance that high-density fiber environments demand. As part of the broader Panduit cable management lineup, it integrates directly with other FiberRunner 12x4 components without adapters or field fabrication.
Key Features
- 90° Vertical Tee Geometry (18" × 8.38" × 14.63"): The fitting measures 18 in. wide, 8.38 in. tall, and 14.63 in. in length — proportions that accommodate 12x4 duct cross-sections cleanly. That 90° drop angle is not arbitrary; it matches the FiberRunner system geometry so mating sections seat flush with no gap or step that could snag fibers during pull or future moves.
- Polycarbonate/ABS Construction: PC/ABS blends trade the brittleness of pure polycarbonate for better impact resistance from ABS while retaining PC's dimensional stability under temperature cycling. In a raised-floor data center where equipment carts and ladder access happen regularly, that matters — a fitting that cracks under incidental impact requires a full fiber re-route to replace.
- RoHS Compliance: Hazardous substance restriction compliance is a procurement requirement in virtually every enterprise and government project today. The FRVT12X4LYL is RoHS-conformant, so it won't hold up a materials declaration or add a line item to your environmental compliance documentation.
- UL-Listed Fiber Optic Cable Routing Assemblies (through 2024): UL listing for optical fiber routing assemblies is required in many commercial building and data center installations by the authority having jurisdiction. This fitting carries that listing, which can be the difference between an accepted inspection and a field remediation order.
- Telcordia GR-63-CORE and NEBS Level 3 Compliance: NEBS Level 3 is the physical and environmental durability benchmark for carrier-grade and central office equipment. Meeting Telcordia GR-63-CORE means this fitting has been tested for seismic, thermal, and mechanical stress conditions that exceed typical enterprise data center requirements — relevant wherever carrier or edge infrastructure is co-located with enterprise gear.
- Yellow Color Coding: Yellow is the fiber optic strand convention in structured cabling environments. Installing yellow fittings in your fiber cable management pathway immediately identifies fiber routes during adds, moves, and changes — reducing the risk of accidentally routing copper into a fiber tray or vice versa during dense infrastructure work.
- Package Quantity of 1: Sold individually, which matters on projects where tee locations are sparse or on change orders where you need a single fitting to complete a section without committing to a full carton quantity.
Integration & Compatibility
The FRVT12X4LYL is designed exclusively for the FiberRunner 12x4 system. It does not cross-fit to FiberRunner 4x4, 6x4, or other duct sizes in the FiberRunner family — the cross-section dimensions are fixed to the 12x4 profile. Plan your pathway before ordering: tee fittings are infrastructure commitments; swapping a tee mid-run after fiber is pulled means clearing the section. For a complete fiber routing pathway, pair this fitting with FiberRunner 12x4 straight sections, covers, elbows, and end caps from the same system family. The NEBS Level 3 and Telcordia GR-63-CORE ratings make it a fit for central office and carrier hotel environments in addition to standard enterprise data centers — consult your local electrical and fire codes to confirm UL listing acceptability for your specific installation jurisdiction.
Frequently Asked Questions
Q: What duct size is the FRVT12X4LYL designed for?
A: The FRVT12X4LYL is sized specifically for the Panduit FiberRunner 12x4 system. It does not fit FiberRunner ducts of other cross-sectional dimensions such as 4x4 or 6x4.
Q: What is the overall size of the FRVT12X4LYL?
A: The fitting measures 18 inches wide (457.2 mm), 8.38 inches tall (212.8 mm), and 14.63 inches in length, accommodating the full 12x4 duct profile at the 90° vertical tee junction.
Q: Is the FRVT12X4LYL RoHS compliant?
A: Yes. The FRVT12X4LYL conforms to RoHS hazardous substance restrictions, satisfying materials declaration requirements for enterprise and government procurement.
Q: Does the FRVT12X4LYL carry a UL listing?
A: Yes. It is listed as part of UL-certified optical fiber cable routing assemblies through 2024, which satisfies authority-having-jurisdiction requirements in many commercial and data center installations.
Q: Is this fitting rated for carrier or central office environments?
A: Yes. The FRVT12X4LYL complies with Telcordia GR-63-CORE seismic and environmental tests and meets Network Equipment Building Systems (NEBS) Level 3 criteria, making it suitable for central office and carrier-grade deployments.
Q: How many fittings are included per order?
A: The FRVT12X4LYL ships as a single unit (package quantity of 1), allowing procurement of individual fittings for specific tee junction points without a minimum carton commitment.
The FRVT12X4LYL is the junction fitting you reach for when a FiberRunner 12x4 horizontal run needs to branch off vertically — a common scenario in data centers where overhead ladder rack feeds down to cabinet top-of-rack entry. The 90° geometry and 18-inch width are fixed to the 12x4 profile, so there's no field cutting or shimming; it either fits your system or it doesn't, and the answer here is straightforward if you're on FiberRunner 12x4.
Technical Highlights:
- NEBS Level 3 / Telcordia GR-63-CORE: Seismic Zone 4 and thermal cycling compliance — if you're routing fiber in a carrier hotel or edge CO where vibration and temperature swing matter, this is the standard to ask for. Most enterprise fittings don't carry it.
- UL-Listed Optical Fiber Routing Assembly: The UL listing is the inspection checkpoint that keeps a project moving. Specifying a non-listed fitting in a commercial data center often surfaces during rough-in inspection; this fitting clears that hurdle.
- PC/ABS Construction: More impact-resistant than straight polycarbonate. In high-traffic data center aisles, that's a practical advantage — the fitting survives incidental contact during equipment moves without developing micro-cracks that could eventually compromise the routing channel.
Deployment Considerations:
- This fitting is system-specific: it integrates only with FiberRunner 12x4 straight sections, covers, and other 12x4 fittings. Confirm your existing or planned pathway is uniformly 12x4 before ordering — mixing duct sizes at a tee is not supported.
- Yellow color-coding aligns with TIA/EIA fiber identification convention, but it is also a system aesthetic commitment. If your installation uses a different color-coding scheme or mixed-fiber/copper routing in the same tray, document the deviation to avoid confusion during future MACs.
For central office buildouts and high-density enterprise data centers where a FiberRunner 12x4 overhead pathway needs a code-compliant, NEBS-rated vertical branch point, the FRVT12X4LYL is the correct fitting — not a generic tee, and not a field-fabricated solution.
