Panduit FRFWC24X4LYL FiberRunner 4-Way Cross Fitting 24x4
Overview
The Panduit FRFWC24X4LYL is a four-way horizontal cross fitting designed for use within the Panduit FiberRunner™ cable management system. It attaches directly to 24x4 FiberRunner channels and fittings to create a horizontal four-directional junction — one input, three output directions — enabling fiber routing paths to branch and cross in the same horizontal plane without additional hardware or field fabrication. The fitting ships individually and is sized for the 24x4 channel profile, making it a purpose-built component rather than a universal adaptor.
If your structured fiber layout requires branching runs to separate racks, cross-aisle distribution, or a hub-and-spoke topology within a fiber cable management pathway, this is the fitting that physically enables that geometry. Without a cross fitting rated for the channel, installers resort to improvised bends or unsupported branch points — both of which create stress on fiber and make future moves/adds/changes significantly harder.
Key Features
- Four-Way Horizontal Cross Geometry: Creates a true horizontal cross with two 24x4 outputs perpendicular to the primary channel run. This matters in high-density data centers where fiber must split to multiple cabinet rows without leaving the protected pathway — eliminating exposed slack and reducing bend-radius violations at branch points.
- Polycarbonate/ABS Construction: The blended polymer body balances the impact resistance of ABS with the dimensional stability of polycarbonate. In a raised-floor or overhead tray environment where technicians regularly brush against fittings during cable pulls, this combination resists cracking under incidental contact better than pure ABS alone.
- Yellow Color Coding: Yellow is the standard identifier for single-mode fiber infrastructure in most data center color-coding conventions. Deploying yellow FiberRunner fittings consistent with yellow fiber gives technicians an immediate visual confirmation of fiber type during moves, adds, and changes — reducing misrouting risk in mixed-media environments.
- RoHS Compliance: The fitting meets RoHS requirements, which is a baseline procurement requirement for most enterprise and government data center projects. If your organization enforces RoHS compliance at the component level, this fitting clears that gate without an exemption request.
- UL-Listed Optical Fiber Cable Guidance Assemblies (to 2024A): The UL listing covers optical fiber cable guidance assemblies under the 2024A standard. This is the certification auditors and AHJs check when verifying that fiber cable management meets NEC and local building code — a listed fitting avoids the inspection friction of unlisted alternatives.
- Telcordia GR-63-CORE and NEBS Level 3 Compliance: GR-63-CORE covers physical protection requirements for network equipment including seismic, thermal, and mechanical stress. NEBS Level 3 is the full telecom carrier-grade standard. For central office and carrier co-location deployments, NEBS Level 3 compliance is frequently a contractual requirement — this fitting satisfies it at the component level.
- 113.8 mm (4.48 in) Overall Height: The 113.8 mm profile is consistent with 24x4 channel geometry, so the cross fitting sits flush within an existing FiberRunner run. Mismatched fitting heights create vertical offsets that stress fiber at the transition — using dimensionally matched fittings eliminates that risk.
- 35.7 in Overall Length: The extended footprint of the cross fitting accommodates the turning radius requirements for 24x4 fiber bundles. Undersized fittings force tighter bends; this geometry keeps fiber within minimum bend radius across all four ports.
Integration & Compatibility
The FRFWC24X4LYL is engineered exclusively for the FiberRunner 24x4 system. It attaches to 24x4 FiberRunner channels and other 24x4 fittings (straights, bends, tees) to build out complete fiber routing pathways. It is not compatible with FiberRunner profiles in other size designations — verify that the installed channel profile is 24x4 before ordering. The fitting is sold as a single unit (Package Quantity: 1), so quantity planning should account for the number of four-way branch points in the routing layout. Applications are listed as data centers and central telecommunications offices, and the Telcordia/NEBS rating extends suitability to carrier and co-location environments with stringent mechanical and environmental standards. For large-scale deployments involving network cable management across multiple rows or floors, mapping branch points in advance before ordering fittings reduces the risk of mid-install procurement delays.
Frequently Asked Questions
Q: What channel size is the FRFWC24X4LYL compatible with?
A: The FRFWC24X4LYL is designed specifically for Panduit FiberRunner 24x4 channels and fittings. It is not interchangeable with other FiberRunner profile sizes. Confirm the installed channel is 24x4 before ordering.
Q: Is the FRFWC24X4LYL RoHS compliant?
A: Yes. The FRFWC24X4LYL meets RoHS compliance requirements, making it suitable for enterprise and government projects with RoHS mandates at the component level.
Q: Does the FRFWC24X4LYL meet NEBS Level 3 requirements?
A: Yes. The fitting is compliant with Telcordia GR-63-CORE and Network Equipment Building Systems (NEBS) Level 3 standards, which are required for carrier-grade central office and co-location deployments.
Q: How many units does the FRFWC24X4LYL ship per order?
A: The FRFWC24X4LYL ships as a single unit (Package Quantity: 1). Plan your order quantity based on the number of four-way cross junction points in your fiber routing layout.
Q: What is the UL listing applicable to the FRFWC24X4LYL?
A: The fitting is UL-listed for optical fiber cable guidance assemblies to the 2024A standard. This listing supports NEC compliance and simplifies AHJ inspections in commercial and carrier installations.
Q: What is the overall height of the FRFWC24X4LYL?
A: The overall height is 4.48 inches (113.8 mm), consistent with the 24x4 FiberRunner channel profile for flush, offset-free integration into existing pathways.
The FRFWC24X4LYL is the fitting you reach for when a FiberRunner 24x4 run needs to branch in two directions simultaneously without leaving the protected pathway. The 113.8 mm height and 35.7-inch overall length are not arbitrary — they are sized to maintain the minimum bend radius for fiber bundles routed through 24x4 channels at all four ports, which is the single most common failure point when integrators use undersized or generic cross fittings at branch junctions.
Technical Highlights:
- NEBS Level 3 / Telcordia GR-63-CORE: This is the full carrier-grade mechanical compliance standard — seismic zone 4, thermal cycling, vibration. If the contract spec calls out NEBS Level 3 at the pathway component level (common in carrier co-lo and central office), this fitting satisfies it. Generic data center fittings typically do not.
- UL Optical Fiber Cable Guidance Assembly (2024A): The UL listing is what an AHJ inspector checks, not the brand name. Having the listing on the fitting itself — not just the channel — closes the inspection loop cleanly without requiring an engineer's letter of equivalence.
- Polycarbonate/ABS blend at this scale: At 35.7 inches overall length, pure ABS would be prone to stress-whitening at the port transitions under repeated cable pull loads. The PC/ABS blend maintains dimensional stability across the full fitting length, which matters when you are routing heavy fiber bundles through a cross junction.
Deployment Considerations:
- The FRFWC24X4LYL ships as a single unit — quantity planning is on the installer. In a pod-based data center layout, count branch points on the routing drawing before procurement; a single missed fitting delays an entire cabinet row installation.
- Yellow color is correct for single-mode fiber conventions, but verify your site's color-coding standard before mixing with an existing multi-mode (aqua/orange) or pre-terminated (manufacturer color) infrastructure — color consistency across a mixed site requires deliberate planning.
For a carrier co-location or central office build where the fiber pathway must satisfy both NEBS Level 3 mechanical specs and UL 2024A listing in a single component, the FRFWC24X4LYL is a documented, specification-compliant solution that removes the compliance documentation burden from the installation team.
