Panduit FRTSC4LBL FiberRunner 4x4 Horizontal Tee Split Cover
Overview
The Panduit FRTSC4LBL is a two-section split cover designed specifically for the FiberRunner 4x4 horizontal tee fitting (FRT4X4LBL), used in data centers and central telecommunications offices where fiber routing integrity and access speed matter. Made from polycarbonate/ABS in black, this cover clips on and off without tools — a practical advantage when technicians are adding or reconfiguring fiber runs under time pressure. The two-section design creates a rounded 19mm opening at the tee junction, so cables can pass through cleanly without sharp-edge contact during moves, adds, and changes.
If you're building out a fiber routing management system with the FiberRunner 4x4 channel infrastructure, this cover is the correct finishing component for horizontal tee junctions. It does one job and does it precisely — protecting the fiber bend radius at the tee while keeping the pathway accessible.
Key Features
- Tool-Free Clip Installation: The snap-clip design means covers can be removed and reinstalled in seconds during cable additions or audits — no screwdrivers, no lost hardware, no downtime waiting on a technician with the right tool. In dense patch environments where tee covers come off routinely, this is the feature that actually saves labor time.
- 19mm Rounded Cable Opening: The two-section construction forms a smooth 19mm aperture at the tee, providing adequate clearance for fiber bundles while maintaining bend-radius protection. Sharp tee edges are the most common cause of fiber jacket damage during pull-through — this rounded geometry eliminates that failure mode.
- Polycarbonate/ABS Construction: The material blend delivers the impact resistance of polycarbonate with the dimensional stability and formability of ABS. In telecom rooms where covers occasionally take tool strikes or get bumped during equipment installs, this matters more than it sounds.
- Matches FRT4X4LBL Tee Fitting: Designed as a direct fit for the Panduit FiberRunner 4x4 horizontal tee — dimensions (12.95 in W × 2.15 in H) are matched to the tee body. Mixing covers across channel sizes or brands risks fit gaps that defeat the purpose of having a cover at all.
- RoHS Compliant: Meets RoHS material restrictions — relevant for projects with environmental compliance requirements or EU market deployments. No exemptions needed for standard data center applications.
- UL Listed to 2024A (Optical Fiber Routing Assemblies): UL certification under the optical fiber cable routing assembly standard confirms the cover has been tested as part of a listed system, not just self-declared. For projects requiring AHJ sign-off or insurance compliance, this is the line item that prevents rework.
- Telcordia GR-63-CORE / NEBS Level 3 Compliance: Tested to the seismic and environmental requirements used for telecommunications network equipment buildings. If your data center is in a seismic zone or the project requires NEBS-grade component documentation, this cover meets the bar without special procurement.
- Sold Individually, Carton of 5 Available: Package quantity is 1 unit, with a carton quantity of 5 — order single pieces for small installations or in case quantities when covering a full row of tee fittings. Pricing is per-unit regardless of carton.
Integration & Compatibility
The FRTSC4LBL is designed for use with the FiberRunner 4x4 system. The cover fits the FRT4X4LBL horizontal tee fitting specifically — not the 2x4, 4x6, or other FiberRunner channel sizes. Before ordering, confirm your installed tee fitting is the 4x4 horizontal variant. The cable management accessories in the FiberRunner line are sized by channel width and height, and a cover from the wrong channel size will not clip correctly or provide proper cable protection. For FiberRunner channel covers on straight runs, Panduit offers separate straight-section cover SKUs matched to the same 4x4 channel body.

Frequently Asked Questions
Q: What tee fitting does the FRTSC4LBL cover fit?
A: The FRTSC4LBL is designed specifically for the Panduit FRT4X4LBL FiberRunner 4x4 horizontal tee fitting. It is not interchangeable with other FiberRunner channel sizes or with vertical tee fittings.
Q: Does the FRTSC4LBL require tools to install or remove?
A: No. The cover uses a clip-on design that allows installation and removal without any tools, making it straightforward to access the tee during cable additions or changes.
Q: What is the cable opening size on the FRTSC4LBL?
A: The two-section design creates a rounded 19mm opening at the tee junction, providing clearance for fiber bundles while protecting cable bend radius.
Q: Is the FRTSC4LBL RoHS compliant?
A: Yes. The FRTSC4LBL meets RoHS material compliance requirements.
Q: Is the FRTSC4LBL UL listed?
A: Yes. It is UL listed for optical fiber cable routing assemblies (UL 2024A) and tested to Telcordia GR-63-CORE and NEBS Level 3 standards.
Q: How many covers come in a package?
A: The FRTSC4LBL is sold as a single unit (package quantity: 1). A carton contains 5 units.
The detail that matters most on the FRTSC4LBL isn't the polycarbonate/ABS blend — it's the 19mm rounded opening the two-section design creates at the tee junction. In practice, that geometry is what prevents jacket abrasion when you're pulling additional fiber through an active tee during a live-site MAC. I've seen installations where the wrong cover (or no cover) left sharp edges at the junction; you don't notice the damage until you're troubleshooting attenuation three months later.
Technical Highlights:
- Tool-Free Clip Mechanism: Snap-on/snap-off without tools cuts per-cover install time to under 30 seconds — meaningful when you're covering a full cabinet row of tee fittings or doing a scheduled MAC window at 2am.
- UL 2024A Listed: The optical fiber routing assembly UL listing is a systems-level certification, not just a component mark. This matters when your GC or AHJ asks for listed pathway documentation — a self-declared cover won't close that punch list item.
- NEBS Level 3 / Telcordia GR-63-CORE: Tested to seismic Zone 4 equivalent requirements. If you're specifying into a carrier hotel, CO, or any facility that enforces NEBS compliance on infrastructure components, this cover is already qualified — no project-specific testing required.
Deployment Considerations:
- Confirm the installed tee is specifically the FRT4X4LBL (4x4 horizontal) before ordering. The FRTSC4LBL dimensions — 12.95 in wide by 2.15 in tall — are matched to that fitting only; the cover will not seat correctly on 2x4 or 4x6 channel tees.
- Package quantity is 1 unit per SKU. If you're covering a full row of tee fittings, price the job at carton quantities (5 per carton) to avoid per-unit freight overhead on what is otherwise a low-cost line item.
The FRTSC4LBL is the right spec for data center build-outs and central office deployments where the FiberRunner 4x4 system is already the standard — particularly in NEBS-required carrier or colocation environments where cover compliance documentation has to survive an audit.
