Panduit FREC24X4LYL FiberRunner 24x4 End Cap
Overview
The Panduit FREC24X4LYL is an end cap fitting designed specifically for the Panduit FiberRunner 24x4 channel system. Its primary function is straightforward but operationally important: it closes the open ends of FiberRunner channels and fittings, completing the protective enclosure around high-performance copper data and fiber optic cabling. Without properly capped ends, channel terminations leave cables exposed to physical damage — a compliance and reliability issue in structured cabling environments. The FREC24X4LYL eliminates that gap with a purpose-fit polycarbonate/ABS cap that matches the 24-inch by 4-inch channel profile exactly.
This fitting is sized for the FiberRunner 24x4 system, with an overall width of 25.68 inches (652.3 mm) and an overall height of 5.71 inches (145 mm), giving it the footprint to fully cover the channel mouth. It ships individually (package quantity of 1), with carton quantities of 5 available for larger rollouts.
Key Features
- Polycarbonate/ABS Construction: The dual-material blend delivers impact resistance from the ABS component and rigidity from the polycarbonate — the right combination for a fitting that needs to stay in place in active cable management environments where technicians are regularly working in trays nearby. You are not dealing with a thin plastic cap that cracks during installation.
- Purpose-Fit for FiberRunner 24x4: Dimensioned at 25.68 in. wide × 5.71 in. tall (652.3 mm × 145 mm), this cap aligns precisely with the FiberRunner 24x4 channel profile. Attempting to adapt a generic end cap to this channel size wastes time and risks an incomplete seal — the FREC24X4LYL mates with the system as-designed.
- Yellow Color Coding: The yellow finish matches the FiberRunner color convention for fiber optic pathways. In a multi-tier cable management installation with both copper and fiber runs, color-consistent fittings reduce mis-routing risk during adds, moves, and changes. Technicians identify fiber pathways visually before touching anything.
- RoHS Compliance: Meets RoHS requirements, which matters if you are deploying into environments with EU-market equipment or customers with environmental materials policies. It is not an afterthought spec — it is a procurement gate for a growing number of enterprise and government facilities.
- UL-Listed Cable Guidance Assemblies (to 2024A): The FiberRunner system assemblies, including this fitting, carry UL listing for optical fiber cable guidance assemblies up to 2024A. This is a code compliance factor in jurisdictions that require listed cable management for fiber installations — confirm with your AHJ if this is a requirement on your project.
- Telcordia GR-63-CORE / NEBS Level 3 Compliance: Tested to Network Equipment Building Systems Level 3 standards and Telcordia GR-63-CORE. NEBS Level 3 is the benchmark for telecom central office equipment and data center infrastructure where seismic, thermal, and physical stress tolerances must be formally validated. If your project involves a carrier-grade or central office environment, this certification is a specification requirement, not a differentiator.
- Single-Unit Packaging (Carton of 5): Ships as a quantity-1 unit with carton quantities of 5. For small retrofits or single-run terminations, you order exactly what you need. For larger deployments with multiple channel termination points, ordering by carton reduces per-unit overhead.
Integration & Compatibility
The FREC24X4LYL is designed exclusively for use with the Panduit FiberRunner 24x4 system. It is not a universal fitting. Before ordering, confirm that your installed channel is the 24x4 FiberRunner profile — Panduit produces FiberRunner in multiple sizes and the end caps are not interchangeable across channel dimensions. The yellow color and 24x4 sizing are the two primary confirmation points.
Typical deployment contexts are data centers and telecommunications central offices, where FiberRunner manages high-density fiber and copper runs above racks or in overhead cable trays. End caps are installed at channel termination points — where a horizontal run ends at a vertical drop, at a wall penetration, or at the terminus of a tray segment. Installing the FREC24X4LYL at these points completes the cable protection structure and keeps the installation code-consistent throughout.

Frequently Asked Questions
Q: What channel system is the FREC24X4LYL compatible with?
A: The FREC24X4LYL is designed specifically for the Panduit FiberRunner 24x4 channel system. It is not a universal end cap and is not interchangeable with other FiberRunner channel sizes.
Q: What does the FREC24X4LYL end cap actually do?
A: It closes the open ends of FiberRunner 24x4 channels and fittings, completing the protective enclosure around fiber optic and copper data cabling and preventing physical damage at channel termination points.
Q: Is the FREC24X4LYL RoHS compliant?
A: Yes. The FREC24X4LYL is RoHS compliant per the standards listed in the product documentation.
Q: Does the FREC24X4LYL meet NEBS Level 3 requirements?
A: Yes. The FiberRunner cable guidance assemblies — including this fitting — are tested to Telcordia GR-63-CORE and Network Equipment Building Systems Level 3 standards, making them suitable for carrier-grade and central office environments.
Q: What are the dimensions of the FREC24X4LYL?
A: The FREC24X4LYL measures 25.68 inches (652.3 mm) wide and 5.71 inches (145 mm) tall, with an overall length of 0.94 inches. These dimensions correspond to the FiberRunner 24x4 channel profile.
Q: How many end caps come in a carton?
A: The FREC24X4LYL ships with a package quantity of 1 and a carton quantity of 5.
The FREC24X4LYL is a detail item — one that gets overlooked in BOMs and then causes a last-minute scramble during punch-out. At 25.68 inches wide and 5.71 inches tall, this end cap closes the full mouth of a FiberRunner 24x4 channel, and the polycarbonate/ABS construction means it is not going to crack when a tech leans a ladder against it six months after installation. I have seen generic caps fail at exactly that point — order the purpose-fit part.
Technical Highlights:
- NEBS Level 3 / Telcordia GR-63-CORE: Tested to the seismic and stress tolerances required for carrier-grade facilities. If your project has a NEBS compliance section in the specs, this fitting satisfies the cable management component — document it at submittal time.
- UL-Listed to 2024A: The cable guidance assembly certification covers this fitting within the FiberRunner system. For permit-required installations where the AHJ is reviewing cable management listings, this is the spec to pull from the submittal package.
- RoHS Compliance: Clears the environmental materials gate for EU-destined equipment and federally contracted facilities that require RoHS documentation. It is on the spec sheet — use it.
Deployment Considerations:
- The FREC24X4LYL is sized exclusively for the FiberRunner 24x4 profile (652.3 mm wide). Verify the installed channel size before ordering — FiberRunner is available in multiple widths and heights, and the end caps do not cross-fit. Check the channel label or measure the opening before you submit a PO.
- Package quantity is 1, carton is 5. For a deployment with more than a handful of channel termination points, order by carton to avoid the unit-level freight cost per fitting. At larger scale, map every open channel end before placing the order — it is easy to undercount in overhead tray work.
For a telecom central office or high-density data center build where the FiberRunner 24x4 system is the backbone of the fiber pathway management, the FREC24X4LYL belongs on the cable management BOM from day one — not as a field afterthought. NEBS Level 3 and UL listing make it the correct specified fitting for carrier and enterprise builds alike.
