Panduit FRSPJC24LYL FiberRunner Spill-Over Junction Cover
The Panduit FRSPJC24LYL is the cover component of the FiberRunner® 4x4 Spill-Over Junction assembly, designed to fully enclose fiber routing at direction-change and transition points in data centers and telco central offices. It pairs with the FiberRunner® Spill-Over Junction base (FRSPJ2X2LYL) to provide a complete, enclosed pathway — keeping fiber protected and routed cleanly without loose covers or secondary fasteners.
Overview
Fiber routing junctions are the points in a tray system most likely to expose cable to mechanical stress, accidental snagging, or EMI ingress if left open. The FRSPJC24LYL addresses this directly: the cover snaps onto the 4x4 FiberRunner® channel base and locks without tools, and the hinged design means you can swing it open to add or remove fiber runs without disturbing adjacent cables or pulling the cover free entirely. In high-density data center environments — where individual fiber circuits can represent significant uptime risk — that access control matters as much as the enclosure itself.
Built from a polycarbonate/ABS blend, the cover handles the mechanical demands of raised-floor and overhead ladder installations without warping under thermal cycling. The yellow color matches the FiberRunner® 4x4 system palette, making it straightforward to trace routing paths visually during audits or adds-moves-changes, particularly useful in dense fiber management environments.
Key Features
- Snap-on, no-tool installation: The cover seats directly onto the FiberRunner® 4x4 channel base without fasteners. In a live data center environment, that means you can close or open a junction point in seconds — reducing the dwell time your fiber spends exposed during maintenance windows.
- Hinged access design: The hinged construction lets you swing the cover open fully without removing it from the channel. This is the practical difference between a cover that supports ongoing MAC work and one that gets set aside and lost during a busy cabinet retrofit.
- Polycarbonate/ABS construction: This blend gives the FRSPJC24LYL the dimensional stability of polycarbonate with the processability of ABS — meaning it holds its snap-fit geometry across the temperature swings typical in active equipment rooms without becoming brittle or deforming the latch.
- Yellow color coding: Matches the FiberRunner® 4x4 system standard color. In a mixed-pathway environment with both copper and fiber trays, color-coded components reduce misrouting risk and speed up visual verification during audits across your Panduit FiberRunner catalog.
- 9-inch width, 4.7-inch height footprint: Sized at 9 in. wide × 4.7 in. tall (228.6 mm × 119.4 mm), the cover is dimensioned to the 4x4 FiberRunner® channel profile — no trimming, no shimming, no adapter plates required when replacing or adding covers in an existing tray run.
- UL Listed to UL 2024: The cover carries UL Listing to the Optical Fiber Cable Routing Assemblies standard, confirming it has passed the fire and mechanical tests required for plenum and general data center pathway deployments where listed assemblies are required by code or by the AHJ.
- Telcordia GR-63-CORE Level 3 compliance: This is the structural and seismic standard that governs network equipment building systems (NEBS). Level 3 compliance means the assembly has been tested against the physical stress conditions — vibration, shock, temperature — that telco central offices are required to survive. If your deployment is a carrier-grade CO or a colocation facility with NEBS requirements, this covers the pathway compliance piece.
- RoHS compliant: Materials meet the EU Restriction of Hazardous Substances directive. Relevant for any deployment that ships equipment internationally or operates under environmental procurement policies.
Integration & Compatibility
The FRSPJC24LYL is engineered specifically for the FiberRunner® 4x4 routing system and is used in conjunction with the FRSPJ2X2LYL Spill-Over Junction base — the cover does not function as a standalone enclosure. Confirm that your installed FiberRunner® base is the 4x4 variant before ordering; FiberRunner® systems are available in multiple channel sizes (2x2, 4x4, etc.) and covers are not cross-compatible between sizes. The yellow color designation matches the standard 4x4 system palette. Sold individually (package quantity: 1), with carton quantities of 5 available for cable management accessory stocking orders.

Frequently Asked Questions
Q: What base component does the FRSPJC24LYL pair with?
A: The FRSPJC24LYL is the cover for the FiberRunner® Spill-Over Junction base, model FRSPJ2X2LYL. The two components work together to form a fully enclosed junction point on a 4x4 FiberRunner® channel run. The cover alone does not form a complete enclosure.
Q: Is the FRSPJC24LYL compatible with FiberRunner® 2x2 channel systems?
A: No. The FRSPJC24LYL is sized for the 4x4 FiberRunner® system (9 in. wide × 4.7 in. tall). FiberRunner® channel sizes are not cross-compatible — confirm your installed base is 4x4 before ordering.
Q: What standards does the FRSPJC24LYL meet?
A: The FRSPJC24LYL is UL Listed to UL 2024 (Optical Fiber Cable Routing Assemblies), compliant with the applicable tests in Telcordia GR-63-CORE Network Equipment Building Systems Level 3, and RoHS compliant.
Q: Does the FRSPJC24LYL require tools to install or remove?
A: No. The cover snaps directly onto the FiberRunner® channel base without fasteners or tools. The hinged design also allows the cover to be opened for cable access without removing it from the channel entirely.
Q: What is the package quantity for the FRSPJC24LYL?
A: The FRSPJC24LYL ships as a single unit (package quantity: 1). Carton quantity is 5 units.
Q: What environments is the FRSPJC24LYL rated for?
A: Panduit specifies the FRSPJC24LYL for data centers and telco central offices. The Telcordia GR-63-CORE Level 3 compliance covers the seismic and environmental stress testing relevant to carrier-grade and NEBS-compliant facilities.
The FRSPJC24LYL is the piece that actually closes out a FiberRunner® 4x4 spill-over junction — without it, you have an open tray transition that looks fine in the as-built drawings and becomes a snagging point the first time anyone works in the overhead. The snap-on, hinged design is the right call here: in a live data center where you cannot take the row offline, the ability to open that junction cover, route a new strand, and re-close it without tools or disturbing adjacent cables is the difference between a clean MAC and a 45-minute remediation.
Technical Highlights:
- UL Listed to UL 2024: Not just a checkbox — UL Listing to the Optical Fiber Cable Routing Assemblies standard is what satisfies many AHJs and colocation operators who require listed pathway assemblies above raised floor. Without it, you may face a punch list item during commissioning.
- Telcordia GR-63-CORE Level 3: This is the NEBS seismic and structural benchmark. If the facility has NEBS requirements written into the spec — common in carrier-grade COs and Tier III+ colo — this component clears that bar on the pathway side without needing a separate compliance exercise.
- Polycarbonate/ABS at 9 in. × 4.7 in.: The dimensional accuracy of the PC/ABS blend ensures the snap-fit geometry stays consistent even after the repeated open/close cycles of an active MAC environment. A cover that loses its snap-fit after a dozen openings is a liability in a high-density fiber plant.
Deployment Considerations:
- The FRSPJC24LYL only functions paired with the FRSPJ2X2LYL base — order both if you are building out new junction points, and verify the base size is 4x4 before pulling from stock. Mismatching with a 2x2 base is the most common field error on FiberRunner® junction orders.
- Carton quantity is 5, but the unit ships as a single. For a large-scale build-out where you need junction covers at every spill-over point across multiple rows, order to the carton to avoid line-item proliferation on the PO.
For a NEBS-compliant telco central office or a Tier III data center where the AHJ requires UL Listed fiber pathways throughout, the FRSPJC24LYL paired with the FRSPJ2X2LYL base is the direct answer — no field fabrication, no unlisted workarounds, and a hinged cover that survives the reality of a working fiber plant.
