Panduit FRFWCSC6LBL FiberRunner 4-Way Cross Split Cover, 6x4, Black
Overview
The Panduit FRFWCSC6LBL is the split cover designed specifically for the FiberRunner 6x4 4-way cross fitting — the lid that closes out your cross junction while still giving technicians snap-off access to add or remove fiber cables without dismantling the run. If you are routing fiber through a wire routing and cable management system in a data center or telecom central office and need a compliant, tool-optional cover at every cross junction, this is the part you order. It is sold as a single unit (Package Qty: 1) and available in case quantities of five.
The FRFWCSC6LBL is built to the same Polycarbonate/ABS blend Panduit uses across the Panduit FiberRunner line, giving you a cover that handles the mechanical and thermal stresses of a live equipment room without warping or becoming brittle over time.
Key Features
- Split-Cover Design for Live Access: The cover creates defined openings at the 4-way cross so you can add or pull fiber without breaking apart the routing system. In a data center where cable adds happen regularly, this means less disruption — no need to unthread an entire run to get one cable in or out.
- Polycarbonate/ABS Construction: The PC/ABS material blend delivers impact resistance and dimensional stability across the temperature swings typical in high-density equipment rooms. This is not a thin snap-on cap — it is the same material grade used across the FiberRunner structural fittings.
- UL Listed (File 2024A): Listed for optical fiber cable routing assemblies, which matters for compliance sign-off in commercial and enterprise installations. Many AHJs and enterprise commissioning teams require UL-listed pathway components — this satisfies that requirement without a variance.
- RoHS Compliant: Meets the Restriction of Hazardous Substances directive, keeping your installation in line with procurement requirements for government, healthcare, and international enterprise projects that mandate RoHS across all installed components including passive infrastructure.
- NEBS Level 3 / Telcordia GR-63-CORE Qualified: Meets the seismic, thermal, and environmental shock requirements of NEBS Level 3, the benchmark for carrier-grade and telecom central office deployments. If you are installing into a telco CO, carrier hotel, or any facility requiring NEBS compliance, this cover is qualified — not just rated, but tested to the relevant GR-63-CORE criteria.
- Black (Color-Coded Infrastructure): Black coloring aligns with standard data center color-coding conventions for fiber pathways and simplifies visual plant documentation. Consistent color across fittings and covers reduces technician error during moves, adds, and changes.
- Sized for 6x4 FiberRunner Systems: At 14.5 in × 14.5 in footprint (368.3 mm × 368.3 mm) and 2.15 in height (54.6 mm), this cover is dimensioned exclusively for the 6x4 FiberRunner cross fitting — not adjustable, not universal. Order the correct fitting size before ordering the cover.
Integration & Compatibility
The FRFWCSC6LBL is compatible exclusively with the Panduit FiberRunner 6x4 system. The 6x4 designation refers to the interior channel dimensions of the FiberRunner trough — 6 inches wide by 4 inches tall. This cover mates to the 4-way cross fitting in that series. It does not fit the 4x4, 2x2, or 10x4 FiberRunner variants, and it is not interchangeable with covers from other Panduit cable management product lines such as Panduct or Wyrduct.
For complete cross junction coverage in a fiber routing system installation, pair this cover with the matching 4-way cross body fitting, straight channels, 90-degree bends, tee fittings, and end caps — all sourced from the FiberRunner 6x4 family. Mixing cover generations or sizes will result in gaps, poor fit, and non-compliant installations.
This fitting and cover combination is suited to data center infrastructure overhead or below-floor fiber routing, telecommunications central offices, and any structured cabling environment where NEBS Level 3 or UL Listed pathway components are specified.

Frequently Asked Questions
Q: What FiberRunner size does the FRFWCSC6LBL fit?
A: The FRFWCSC6LBL is designed exclusively for the Panduit FiberRunner 6x4 system — specifically the 4-way cross fitting in that channel size. It will not fit the 4x4, 2x2, or 10x4 FiberRunner variants.
Q: Is the FRFWCSC6LBL UL Listed?
A: Yes. The FRFWCSC6LBL is UL Listed under File 2024A for optical fiber cable routing assemblies, satisfying UL compliance requirements for commercial and enterprise structured cabling installations.
Q: Does the FRFWCSC6LBL meet NEBS Level 3 requirements?
A: Yes. It meets the requirements for the relevant tests in Telcordia GR-63-CORE and qualifies at NEBS (Network Equipment Building Systems) Level 3, making it suitable for carrier-grade and telecom central office installations where NEBS compliance is specified.
Q: Is the FRFWCSC6LBL RoHS compliant?
A: Yes. The FRFWCSC6LBL is RoHS compliant, meeting the Restriction of Hazardous Substances directive requirements relevant for government, healthcare, and international enterprise procurement mandates.
Q: What are the dimensions of the FRFWCSC6LBL?
A: The cover measures 14.5 in × 14.5 in (368.3 mm × 368.3 mm) in footprint with a height of 2.15 in (54.6 mm). These dimensions correspond to the 6x4 FiberRunner 4-way cross fitting geometry.
Q: How many covers come in a package?
A: The FRFWCSC6LBL ships as a single unit (Package Qty: 1). Case quantity is 5 units per carton — order multiples for large-scale cross junction coverage across a run.
The FRFWCSC6LBL is a detail that separates a finished fiber plant from a half-done one. I see data center installations where the routing channels are fully populated but cross junctions are left open — that is an invitation for cable sag, dust ingress, and technician snag points during future pulls. This cover closes the 6x4 4-way cross cleanly, and the split design means you are not re-opening the whole run every time someone needs to add a strand.
Technical Highlights:
- NEBS Level 3 / GR-63-CORE: This is not a paperwork rating — it means the cover has been tested to the seismic zone 4 and thermal shock criteria that carrier facilities actually enforce. If your spec sheet calls out NEBS, this cover keeps the pathway assembly compliant end-to-end.
- UL Listed File 2024A: Covers fiber routing assemblies specifically — not just a generic plastic UL listing. That distinction matters when an AHJ inspector is checking pathway compliance on a commercial project.
- Polycarbonate/ABS at 14.5 × 14.5 in: The PC/ABS blend at this footprint size holds its geometry without creep under the cable weight common in a fully loaded 6x4 cross. A purely ABS cover of this size can deflect over time; the polycarbonate content resists that.
Deployment Considerations:
- Verify your cross fitting part number is the 6x4 variant before ordering — the FRFWCSC6LBL will not adapt to other FiberRunner channel sizes, and Panduit does not publish a universal cross cover.
- Case quantity is 5 units per carton. For a large overhead grid with multiple cross junctions, calculate your cross count and order in case multiples to avoid partial-carton reorder delays mid-installation.
This cover belongs in any telecom central office or enterprise data center where the fiber pathway is specified to NEBS Level 3 and the project requires fully closed, UL Listed routing at every cross junction — not just along the straights.
