Panduit FRIVRA4X4LYL FiberRunner 4x4 Inside Vertical 90-Degree Fitting
Overview
The Panduit FRIVRA4X4LYL is an inside vertical 90-degree fitting designed for the Panduit FiberRunner 4x4 system. It creates a controlled upward bend from a straight horizontal run — the component you reach for when your fiber routing system needs to change planes without introducing stress on delicate fiber optic strands. Built from Panduit's Polycarbonate/ABS blend and finished in high-visibility yellow, it is engineered specifically for data center and telecommunications central office environments where cable management precision directly affects long-term system integrity.
Key Features
- Inside Vertical 90-Degree Geometry: Creates a controlled upward bend from horizontal — no improvised bends that violate fiber bend-radius specs. This is the fitting that keeps bend-sensitive single-mode fiber within manufacturer-rated minimums on vertical transitions.
- Pairs with FROVRA4X4LYL Outer Fitting: Used alongside the outside vertical 90-degree connector (FROVRA4X4LYL) to execute a full plane change on a straight horizontal run. Both pieces are required to complete the transition — plan your bill of materials accordingly.
- Polycarbonate/ABS Construction: The material blend balances rigidity with impact resistance, so the fitting holds its geometry under cable load without cracking during installation or in environments with temperature cycling.
- High-Visibility Yellow: The yellow color coding matches the 4x4 FiberRunner channel system and makes fiber pathways immediately identifiable during maintenance, reducing the risk of accidental cable disturbance in dense rack rows.
- 5.55 in. × 8.64 in. Footprint: At 140.9 mm × 219.4 mm, this fitting accommodates the full 4x4 channel cross-section. Confirm your overhead or under-floor routing has clearance for these dimensions before finalizing the layout.
- UL Listed (2024A) for Fiber Optic Raceways: Meets UL 2024A requirements for fiber optic cable routing assemblies — required for compliant installation in many commercial and government facilities.
- NEBS Level 3 / Telcordia GR-63-CORE Compliance: Satisfies the seismic, thermal, and mechanical stress requirements that carriers and co-location operators mandate for central office and telecom exchange deployments. If your customer spec sheet calls out NEBS, this fitting covers it.
- RoHS Compliant: Meets EU RoHS requirements, supporting deployment into environmentally regulated facilities and projects with green-building or procurement compliance requirements.
Integration & Compatibility
The FRIVRA4X4LYL is purpose-built for the 4x4 FiberRunner raceway system and is not interchangeable with other channel sizes. For a complete vertical plane change, pair this inside fitting with the FROVRA4X4LYL outside vertical fitting. Both are sold individually — Carton Qty is 5 units, Package Qty is 1. When integrating into a data center cable management design, verify that adjacent straight sections and connector fittings are also 4x4 series to maintain consistent bend-radius control and channel continuity across the entire fiber pathway.
Frequently Asked Questions
Q: What channel size is the FRIVRA4X4LYL compatible with?
A: The FRIVRA4X4LYL is designed exclusively for the Panduit FiberRunner 4x4 system. It is not compatible with other FiberRunner channel sizes (2x2, 4x2, etc.).
Q: Does the FRIVRA4X4LYL require a companion fitting to complete a vertical plane change?
A: Yes. The inside vertical fitting (FRIVRA4X4LYL) must be paired with the outside vertical 90-degree fitting, model FROVRA4X4LYL, to fully execute a plane change on a horizontal run.
Q: Is the FRIVRA4X4LYL NEBS compliant?
A: Yes. It meets the requirements for relevant tests in Telcordia GR-63-CORE and NEBS (Network Equipment Building Systems) Level 3, making it suitable for carrier and co-location central office installations.
Q: Is the FRIVRA4X4LYL RoHS compliant?
A: Yes. The fitting is RoHS compliant and UL listed under 2024A for fiber optic cable routing assemblies.
Q: How many fittings come in a package?
A: Package Quantity is 1 fitting per package. Carton Quantity is 5 units.
The FRIVRA4X4LYL is the fitting that separates a properly engineered fiber pathway from a makeshift one. At 219.4 mm tall and 140.9 mm wide, it fills the full 4x4 FiberRunner cross-section on a vertical inside bend — meaning your fiber strands are guided, not bent free-hand around a corner where nobody checked the bend radius.
Technical Highlights:
- NEBS Level 3 / GR-63-CORE: Carrier-grade seismic and environmental compliance built into a passive fitting — required language on most telco and co-lo RFPs, and this fitting checks that box without a separate waiver process.
- UL 2024A Listing: The UL listing is for fiber optic cable routing assemblies specifically, not a generic electrical listing — relevant when your AHJ or general contractor requires documented compliance for the complete fiber pathway, not just the cable itself.
- Polycarbonate/ABS Material: Rigid enough to hold cable weight and geometry under load, but not brittle — this matters in installations where technicians are pulling slack or rerouting adjacent cables post-commissioning.
Deployment Considerations:
- This fitting is inside-only — it does not complete the plane change on its own. Budget FROVRA4X4LYL (outside vertical 90°) as a paired line item; missing it means the transition is incomplete and the outer channel wall is open.
- The 5.55 in. × 8.64 in. footprint requires clear overhead or under-floor space at every transition point — verify this in your rack-elevation and floor-plan drawings before ordering, especially in retrofits where overhead cable trays are already densely routed.
This fitting is the right specification for new data center builds and telecom exchange upgrades where the project documents call out NEBS Level 3, UL 2024A, or RoHS — and where the fiber pathway design uses the Panduit 4x4 FiberRunner channel throughout.
