Panduit FIV452X2LBL FiberRunner 2x2 Inside Vertical 45-Degree Fitting
Overview
The Panduit FIV452X2LBL is an inside vertical 45-degree bend fitting for the Panduit FiberRunner 2x2 fiber cable management system. It routes fiber from a straight horizontal run upward at 45 degrees — the inside fitting that pairs with the outside vertical connector (FOV452X2LBL) when you need to change the plane of a horizontal run without exceeding fiber bend radius limits. The FIV452X2LBL measures 7.79 in. wide × 4.73 in. tall (197.9 mm × 120.1 mm), molded in black Polycarbonate/ABS for long-term structural stability in high-density environments. Sold individually (package quantity: 1), with a carton quantity of 5 for larger deployments.
Key Features
- 45-Degree Inside Vertical Geometry: Creates an upward bend from a straight horizontal FiberRunner run. Pair this fitting with the outside FOV452X2LBL connector to complete a full plane change — you need both pieces to make the transition work, so order both together on any structured cabling project.
- Polycarbonate/ABS Construction: This material combination delivers the impact resistance of polycarbonate with ABS processability. In data centers where installers regularly dress and redress cable, the fitting holds its shape under repeated use — it won't crack or deform under normal cable load in the 2x2 pathway.
- UL Listed (2024A): Listed specifically for fiber optic cable raceway assemblies, confirming the fitting meets the flammability and mechanical requirements for permanent data center infrastructure. Relevant if your project requires listed components for code compliance or insurance purposes.
- NEBS Level 3 / Telcordia GR-63-CORE Compliance: Meets seismic, thermal, and mechanical stress requirements for telecom central offices and carrier-class data centers. If your facility enforces NEBS certification on all pathway hardware, the FIV452X2LBL satisfies that requirement without a waiver.
- RoHS Compliant: Hazardous-substance restricted, which matters for government, healthcare, and multinational deployments subject to environmental compliance audits.
- Designed for Data Centers and Telecom Central Offices: The FiberRunner system is purpose-built for data center and telecom infrastructure — not a general-purpose cable tray adaptation. This translates to tighter dimensional tolerances and consistent compatibility across the full FiberRunner fitting family.
- 2x2 System Compatibility: The FIV452X2LBL is sized for the 2x2 FiberRunner routing system. It is not interchangeable with 4x4 or 4x2 FiberRunner fittings — verify your installed pathway size before ordering.
Integration and Compatibility
The FIV452X2LBL is designed exclusively for Panduit's FiberRunner 2x2 fiber routing system. The inside vertical fitting works in tandem with the FOV452X2LBL outside vertical fitting to complete a 45-degree plane change on a horizontal run. Review your cable pathway layout before specifying quantities — each direction change in the run requires the corresponding inside and outside fitting pair. This fitting does not include splice connectors or mounting hardware; those are specified separately based on your pathway configuration.
Frequently Asked Questions
Q: What is the FIV452X2LBL used for?
A: The FIV452X2LBL is the inside vertical 45-degree fitting for the Panduit FiberRunner 2x2 fiber routing system. It creates a 45-degree upward bend from a straight horizontal run and must be paired with the outside vertical fitting FOV452X2LBL to complete the plane change.
Q: Does the FIV452X2LBL work with FiberRunner 4x4 or other sizes?
A: No. The FIV452X2LBL is sized specifically for the 2x2 FiberRunner pathway. It is not compatible with 4x4, 4x2, or other FiberRunner channel sizes. Verify your installed pathway dimensions before ordering.
Q: Is the FIV452X2LBL UL listed?
A: Yes. The FIV452X2LBL is UL listed under standard 2024A for fiber optic cable raceway assemblies, confirming compliance with flammability and mechanical requirements for permanent infrastructure installation.
Q: Does the FIV452X2LBL meet NEBS requirements?
A: Yes. The fitting meets the relevant test requirements of Telcordia GR-63-CORE and NEBS (Network Equipment Building Systems) Level 3, making it suitable for carrier-class data centers and telecom central offices with strict infrastructure certification requirements.
Q: How many pieces come in a package?
A: The FIV452X2LBL ships in a package quantity of 1. The carton quantity is 5, so orders of 5 or more typically ship in full carton units.
Q: Is the FIV452X2LBL RoHS compliant?
A: Yes. The FIV452X2LBL is RoHS compliant, meeting EU restrictions on hazardous substances — relevant for government, healthcare, and multinational deployments subject to environmental compliance audits.
The FIV452X2LBL is one of those fittings that looks simple until you're on site trying to route fiber up into an overhead tray and realize you ordered only the outside vertical piece. This fitting handles the inside radius of the 45-degree bend in the Panduit FiberRunner 2x2 system — it measures 7.79 in. wide and 4.73 in. tall, and it does not work alone. The FOV452X2LBL outside fitting is the required complement; both pieces together complete the plane change.
Technical Highlights:
- NEBS Level 3 / GR-63-CORE: Meets seismic and mechanical stress qualifications for carrier facilities — if your project spec sheet calls out NEBS-compliant pathway hardware, this fitting satisfies that line item without requesting an exception.
- UL 2024A Listing: Listed for fiber optic cable raceway assemblies specifically, not just general cable management — relevant when the AHJ or insurance underwriter requires listed raceways throughout the data center infrastructure.
- Polycarbonate/ABS Body: More impact-resistant than pure ABS alternatives; holds dimensional tolerances through repeated cable redressing cycles without cracking at the fitting corners where stress concentrates.
Deployment Considerations:
- Always order the FOV452X2LBL outside vertical fitting alongside the FIV452X2LBL — the inside fitting alone leaves the bend incomplete. Budget both SKUs per direction change in your pathway layout.
- The 2x2 channel size is a hard constraint: FiberRunner fittings are not interchangeable across channel dimensions. Confirm the installed pathway is 2x2 before procurement, especially on retrofit projects where the existing infrastructure may be a mix of channel sizes.
The FIV452X2LBL is the right spec for carrier-class data centers and telecom central offices where NEBS Level 3 compliance is a contractual requirement and where the FiberRunner 2x2 system is already the installed standard for horizontal fiber routing.
