Panduit FRRASC12LYL FiberRunner 12x4 Horizontal Right-Angle Split Cover
Overview
The FRRASC12LYL is a two-section split cover designed specifically for the Panduit FiberRunner™ 12x4 horizontal right-angle fitting (FRRA12X4LYL). If you're managing high-density fiber routing in a cable management installation and need to protect the bend point where fiber changes horizontal direction, this cover closes out that fitting without requiring you to disassemble routed cables to install or remove it. The polycarbonate/ABS construction and tool-free clip-on attachment make this practical in live environments where you can't take fiber offline to perform maintenance. The FRRASC12LYL is sold individually (package quantity of one), though carton quantities of five are available for larger deployments.
Key Features
- Tool-Free Clip-On Attachment: The clip-on design lets you install or remove the cover without tools — meaningful in dense telecom rooms and data centers where reaching into a populated rack or tray with a screwdriver is genuinely difficult. No need to clear adjacent cables to access the fitting.
- 19 mm Rounded Access Opening: The two-section design creates a 19 mm (approximately 3/4 inch) rounded opening at the junction, giving you a defined access point for adding or removing fiber cables after the cover is in place. This avoids the common problem of a closed cover that forces you to pull the entire section to route a single new cable.
- Polycarbonate/ABS Construction: The material combination provides the rigidity needed to protect fibers at a bend point while resisting the brittleness of pure polycarbonate in high-traffic environments. In data centers where cable management is regularly accessed, a cover that cracks under light impact becomes a maintenance liability.
- 17.99-Inch Length, 2.79-Inch Height: At 17.99 in (approximately 457 mm) long and 70.9 mm tall, the FRRASC12LYL matches the geometry of the FRRA12X4LYL fitting it protects. Verify the fitting dimensions before ordering — this cover is dimensioned specifically for the 12x4 FiberRunner family, not the 4x4 or 6x4 variants.
- Yellow Color (Jaune): The yellow finish matches the standard Panduit FiberRunner™ system color coding for fiber pathways, maintaining visual consistency across your installation and helping technicians distinguish fiber runs from copper or power pathways at a glance.
- RoHS Compliant: RoHS compliance is a procurement requirement for many enterprise and government data center projects. The FRRASC12LYL meets this standard, so it won't block your project from passing an environmental materials audit.
- UL Listed (Optical Cable Routing Assemblies through 2024) and Telcordia GR-63-CORE / NEBS Level 3 Compliance: UL listing for optical cable routing assemblies confirms the cover meets recognized safety standards for the application. NEBS Level 3 compliance — which covers seismic zone 4 performance, thermal shock, vibration, and airborne contaminants — means this cover is qualified for carrier-grade central office environments, not just enterprise data centers. If your project includes a telecom central office or carrier facility, this certification matters for acceptance.
Integration & Compatibility
The FRRASC12LYL is a direct companion to the Panduit FiberRunner™ 12x4 horizontal right-angle fitting (FRRA12X4LYL). It is designed exclusively for the 12x4 FiberRunner system deployed in data center and central office cable management applications. It does not fit the 4x4 or 6x4 FiberRunner series — those fittings have different cross-section dimensions and require their own cover SKUs. If you are building out a complete FiberRunner pathway, pair this cover with the corresponding FRRA12X4LYL right-angle fitting and the broader fiber routing channel components in the same family. The clip-on mounting is compatible with the standard FiberRunner channel profile — no additional hardware or adhesives are required.

Frequently Asked Questions
Q: What fitting does the FRRASC12LYL cover, and will it fit other FiberRunner sizes?
A: The FRRASC12LYL is designed specifically for the Panduit FiberRunner 12x4 horizontal right-angle fitting (FRRA12X4LYL). It is not compatible with 4x4 or 6x4 FiberRunner fittings, which have different cross-section dimensions and require their own cover SKUs.
Q: Do I need tools to install or remove the FRRASC12LYL?
A: No. The clip-on design allows the cover to be installed and removed without tools, which is particularly useful in live environments where fiber cables remain in the tray during maintenance.
Q: Is the FRRASC12LYL RoHS compliant?
A: Yes. The FRRASC12LYL meets RoHS requirements, making it suitable for projects with environmental materials compliance requirements.
Q: Is the FRRASC12LYL NEBS Level 3 compliant?
A: Yes. The FiberRunner system including this cover meets Telcordia GR-63-CORE and Network Equipment Building Systems (NEBS) Level 3 standards, qualifying it for carrier-grade central office and telecom facility deployments.
Q: How many covers come in a package?
A: The FRRASC12LYL ships with a package quantity of one. Cartons contain five units, so if you're ordering for multiple fittings, confirm whether you need single units or full carton quantities.
Q: What is the access opening size on the FRRASC12LYL two-section design?
A: The two-section cover creates a 19 mm rounded opening at the fitting junction, allowing cables to be added or removed without fully removing the cover.
The FRRASC12LYL is a detail that separates a finished fiber installation from one that will cause problems during the next MACs cycle. The 19 mm rounded access opening in the two-section design is the spec I'd point to first — it means a technician can add a fiber run at the right-angle bend without pulling the cover entirely and disturbing existing cables. In a carrier central office or dense data center where fiber pathways are touched regularly, that matters more than it sounds.
Technical Highlights:
- Tool-Free Clip-On: No tools required for install or removal — in a rack row where clearance is tight and cables are live, this eliminates the risk of dropped hardware or accidental fiber movement during cover access.
- NEBS Level 3 / Telcordia GR-63-CORE: Qualifies the cover for carrier-grade environments including seismic zone 4 — a hard requirement for central office acceptance testing that purely enterprise-grade cable management products won't pass.
- Polycarbonate/ABS, Yellow, 17.99 in Length: The yellow color matches the FiberRunner fiber pathway standard, making audits and adds faster; the material holds up to repeated install/remove cycles without the cracking risk of pure PC covers.
Deployment Considerations:
- Confirm you are ordering against the FRRA12X4LYL fitting specifically — the cover dimensions (17.99 in length, 70.9 mm height) are sized to the 12x4 channel cross-section and will not seat correctly on 4x4 or 6x4 FiberRunner right-angle fittings.
- Package quantity is one unit per order; if you are covering multiple right-angle fittings in a single installation, order in carton quantities of five to avoid per-unit shipping overhead on a repeat accessory.
This cover is the right spec for carrier central office builds and enterprise data centers deploying FiberRunner 12x4 pathways where NEBS Level 3 compliance is a contract requirement and ongoing cable adds are expected throughout the infrastructure lifecycle.
