Panduit FROVRA4X4LBL FiberRunner 4x4 Vertical Outside Corner
The Panduit FROVRA4X4LBL FiberRunner vertical outside corner creates a 90-degree vertical transition from horizontal fiber cable pathways in datacenter and telecommunications installations. This polycarbonate/ABS fitting is engineered for the FiberRunner 4x4 system, enabling installers to route fiber bundles vertically while maintaining proper bend radius and clean cable management. Designed for environments requiring NEBS Level 3 compliance, this corner fitting pairs with the inside vertical corner (FRIVRA4X4LBL) to complete plane changes in multi-tier rack installations.
Key Features
- 90-degree vertical outside corner for FiberRunner 4x4 raceway system
- Polycarbonate/ABS construction for impact resistance and flame rating
- 7.74" height x 5.49" width footprint fits standard 19" rack mounting configurations
- UL 2024A listed for fiber optic cable routing assemblies
- NEBS Level 3 qualified per Telcordia GR-63-CORE for seismic and environmental stress
- Black finish integrates with datacenter aesthetics
This vertical outside corner measures 7.74 inches in height and length, and 5.49 inches in width—dimensioned to transition from horizontal FiberRunner pathways mounted along walls or under raised floors to vertical riser sections feeding overhead cable trays or rack-mounted equipment. The polycarbonate/ABS blend provides the mechanical strength required for unsupported vertical spans while maintaining UL flame ratings. When paired with the inside vertical corner (part FRIVRA4X4LBL), the two-piece assembly creates a complete 90-degree plane change that preserves the 4x4 pathway cross-section throughout the transition. The snap-together FiberRunner design allows installers to build vertical transitions without cutting or fastening, reducing installation time on large-scale datacenter builds or telecom central office deployments.
Datacenter and telecommunications integrators deploying multi-mode or single-mode fiber trunks between distribution frames, zone enclosures, and core switches use FiberRunner vertical corners to organize pathways in hot-aisle/cold-aisle layouts. The 4x4 cross-section accommodates high-density fiber bundles—typically 144-fiber to 288-fiber trunk assemblies—while the smooth interior contours prevent jacket abrasion during cable pulls. The NEBS Level 3 qualification means this fitting has passed the earthquake, temperature cycling, fire, and corrosive atmosphere tests required for telecom carrier installations under Telcordia GR-63-CORE, making it appropriate for Tier 3+ datacenters and carrier-grade telecom facilities where equipment must remain operational during seismic events or environmental stress.
This fitting ships individually packaged (cartons of 5) and is RoHS compliant. The UL 2024A listing specifically covers fiber optic cable routing assemblies, confirming the product meets the National Electrical Code requirements for communications pathways—critical for projects requiring AHJ approval or carrier specifications that mandate UL-listed components. For projects requiring vertical transitions in FiberRunner 4x4 deployments, this outside corner is the engineered component that maintains pathway integrity, cable protection, and code compliance from horizontal to vertical routing sections.
