Panduit FREC24X4LBL FiberRunner 24x4 End Cap
Overview
The Panduit FREC24X4LBL is an end cap designed specifically for the FiberRunner 24x4 fiber routing channel system. It closes off open channel and fitting ends to form a fully enclosed pathway, shielding high-performance copper data and fiber optic cables from physical damage at termination points. At 25.68 inches wide and 5.71 inches tall, this end cap matches the full cross-section of the 24x4 FiberRunner channel — when you need a clean, protected cable run that doesn't leave fiber exposed at the end of a run or at a junction, this is the piece that completes it. For anyone specifying Panduit FiberRunner systems in a structured cabling deployment, this end cap is a required finish component, not an afterthought.
Molded from a Polycarbonate/ABS blend, the FREC24X4LBL offers the dimensional stability and impact resistance expected in data center and central office environments where cable management hardware takes real mechanical stress during installation and maintenance. The black finish integrates with the standard FiberRunner color scheme used across most raised-floor and overhead fiber routing systems.
Key Features
- Full-width closure for 24x4 FiberRunner channel: At 25.68 in. (652.3 mm) wide and 5.71 in. (145 mm) tall, this end cap covers the complete opening of a 24x4 FiberRunner channel — no partial coverage, no exposed cable edges. In a production data center, an unsealed channel end is a snag and damage point during any cable moves-adds-changes; this eliminates that risk.
- Polycarbonate/ABS construction: The blend delivers high impact resistance without the brittleness of pure polycarbonate — relevant during installation when end caps get handled repeatedly and occasionally dropped on hard flooring. It also holds its shape under the compressive load of a full 24x4 bundle without deforming the seal.
- RoHS compliance: Meets RoHS requirements, which matters for data centers operating under EU environmental compliance mandates or for enterprise buyers whose procurement policies require RoHS-compliant infrastructure components throughout the cable pathway.
- UL-listed for optical fiber cable guidance assemblies up to 2024A: The UL listing to 2024A means this end cap is recognized as part of a listed cable routing assembly — important for facilities where the AHJ (authority having jurisdiction) requires listed cable management hardware in the pathway, not just the cable itself.
- Telcordia GR-63-CORE and NEBS Level 3 compliance: Telcordia GR-63-CORE covers seismic and environmental stress; NEBS Level 3 is the benchmark for central office and carrier-grade environments. If you're specifying network infrastructure in a telco central office or any facility requiring NEBS-grade components, this end cap meets that bar — most generic cable management accessories do not.
- Designed for FiberRunner 24x4 system: Engineered to mate with the FiberRunner 24x4 channel (24 in. wide × 4 in. deep). This is a system-matched part, not a universal fit — which means correct dimensional alignment and consistent aesthetics across the entire cable management run without field modification.
- Package quantity of 1, carton quantity of 5: Sold individually, so you can order exactly the quantity your installation requires without committing to a full carton. For large deployments specifying multiple FiberRunner runs, the carton pack of 5 makes bulk procurement straightforward.
Integration & Compatibility
The FREC24X4LBL is specified for use with the FiberRunner 24x4 system (channel and fittings). It is not dimensionally compatible with other FiberRunner channel sizes — verify your installed channel is the 24x4 variant before ordering. The cable management accessory line includes fittings, covers, and splice plates that pair with this channel size; the end cap is the terminal component at any open run end or unused fitting port.
For data center deployments that also require PoE switch infrastructure or structured cabling planning, coordinating your fiber pathway layout with your PoE switch placement early reduces the number of channel terminations required and simplifies the end cap count in your bill of materials.

Frequently Asked Questions
Q: What channel size is the FREC24X4LBL designed to fit?
A: The FREC24X4LBL is designed exclusively for the FiberRunner 24x4 channel system — 24 inches wide by 4 inches deep. It is not compatible with other FiberRunner channel sizes. Verify your installed channel dimensions before ordering.
Q: Is the FREC24X4LBL RoHS compliant?
A: Yes. The FREC24X4LBL is RoHS compliant, making it suitable for deployments subject to EU environmental compliance requirements or enterprise procurement policies that require RoHS-compliant cable management components.
Q: Does the FREC24X4LBL meet NEBS Level 3 requirements?
A: Yes. The FREC24X4LBL complies with Telcordia GR-63-CORE and Network Equipment Building Systems (NEBS) Level 3 standards — the benchmark for carrier-grade and central office environments. This makes it appropriate for telco central office installations where NEBS-grade components are required throughout the cable pathway.
Q: Is the FREC24X4LBL UL listed?
A: Yes. It carries a UL listing for optical fiber cable guidance assemblies up to 2024A, which is relevant when the AHJ requires listed cable management hardware in the fiber pathway.
Q: How many end caps come in one order?
A: The FREC24X4LBL ships with a package quantity of 1 unit. The full carton contains 5 units. Order the quantity that matches your installation requirement.
Q: What material is the FREC24X4LBL made from?
A: It is molded from a Polycarbonate/ABS blend, which provides impact resistance and dimensional stability under the mechanical stress of data center and central office installation and maintenance cycles.
The FREC24X4LBL is a straightforward component, but its NEBS Level 3 and Telcordia GR-63-CORE compliance make it a non-trivial spec decision for anyone building out a carrier-grade or central office fiber pathway. At 25.68 inches wide and 5.71 inches tall, it covers the full cross-section of a 24x4 FiberRunner run — and in environments where that compliance certification is required by the AHJ or the facility's own standards, substituting a generic end cap introduces a listed-assembly gap that can create inspection problems downstream.
Technical Highlights:
- NEBS Level 3 / GR-63-CORE: Meets the seismic and environmental stress standards required in telco central offices — a specification most generic cable management accessories skip entirely. If your facility requires NEBS-grade throughout, this is the correct part.
- UL 2024A listing: Recognized as part of a listed optical fiber cable guidance assembly — relevant whenever the AHJ requires listed cable management hardware, not just listed cable.
- Polycarbonate/ABS construction: Dimensionally stable under the compressive loads of a full 24x4 fiber bundle, and impact-resistant enough to survive repeated installation and maintenance handling without cracking or deforming the seal.
Deployment Considerations:
- This end cap is dimensionally matched to the 24x4 FiberRunner channel only — 25.68 in. wide × 5.71 in. tall. Confirm your installed channel size before ordering; the FiberRunner line includes multiple channel widths and a wrong-size end cap will not seat correctly.
- Package quantity is 1 unit per order (carton = 5). For a large data center fit-out with many FiberRunner runs, calculate your open-end count before ordering to avoid multiple small shipments.
Best deployment fit: carrier-grade central offices, Tier III/IV data centers, and enterprise core switch rooms where the cable management pathway is subject to formal inspection and NEBS or UL listing requirements are enforced — not just a convenience purchase for general office cabling.
