Panduit PWBIB4BL Wire Basket Radius Intersection Kit

The Panduit PWBIB4BL is a four-piece radius intersection bracket kit engineered for 90-degree turns in 4" height wire basket cable tray systems. Constructed from powder-coated steel, this intersection hardware maintains pathway integrity at tray junctions while preserving the equipment grounding conductor continuity required by NEC 392.3(C) and 392.7(B). Designed for datacenters, industrial facilities, and large commercial installations where structured cabling demands clean, code-compliant directional changes without compromising fill capacity or cable bend radius.

Wire basket cable tray intersections represent a critical junction point where pathway integrity, grounding continuity, and cable protection converge. The PWBIB4BL addresses all three requirements with a bracket assembly that clamps securely to perpendicular tray runs, forming a radiused corner that guides cables through the turn without exceeding minimum bend radius limits. The four-bracket configuration distributes mechanical load evenly across both incoming and outgoing tray sections, preventing stress concentration that can deform lightweight wire mesh under heavy cable fills. Powder-coated steel construction provides the structural rigidity needed to support bundled Cat6A, fiber trunk, and power cabling in converged pathway applications.

UL Classification as an Equipment Grounding Conductor means this intersection kit maintains the electrical continuity that allows wire basket tray to function as the grounding path for connected devices—eliminating the need for separate ground wires in many installations. The bracket's steel-to-steel contact with tray side rails ensures low-impedance bonding across the 90-degree junction, meeting NEC requirements for fault current return paths. This grounding function is especially valuable in PoE switch deployments, IP camera trunk runs, and access control risers where the tray itself serves as the grounding backbone for dozens of endpoints. Black powder coat provides corrosion resistance in climate-controlled indoor spaces while maintaining the conductive metal-to-metal joints required for grounding performance.

Installation integrates with standard wire basket tray assembly practices—brackets bolt to tray side rails using existing mounting holes, with no welding or custom fabrication required. The pre-formed radius geometry eliminates the guesswork in achieving compliant cable bending angles, particularly critical for high-pair-count copper and bend-sensitive fiber trunk cables. For integrators managing large-scale structured cabling projects, the PWBIB4BL reduces labor time at every perpendicular junction while ensuring inspection-ready NEC compliance and protecting cable performance over the life of the installation.
