Panduit PWBPF4X8WH Wire Basket Tray Tee-Intersection Bracket

The Panduit PWBPF4X8WH is a powder-coated steel tee-intersection bracket engineered for joining three runs of 4" × 8" wire basket tray at 90-degree angles. UL classified for use as an equipment grounding conductor per NEC 392.3(C) and 392.7(B), this white-finish fitting maintains grounding continuity across branch points while supporting the mechanical and electrical demands of data center, telecom, and commercial AV installations. When your pathway design calls for T-junctions — whether splitting a main trunk to feed a row of racks or creating perpendicular drops to wall-mounted equipment — this bracket provides the structural tie-in and code-compliant bonding path your inspector expects.

Key Features

• UL classified as equipment grounding conductor — meets NEC 392.3(C) and 392.7(B) requirements for metallic cable tray bonding
• Powder-coated steel construction resists corrosion in climate-controlled and light-duty industrial environments
• White finish integrates with clean-room, office, and customer-facing infrastructure where exposed pathways must match architectural standards
• 4" × 8" dimensional compatibility aligns with Panduit's PW-series wire basket tray and cross-compatible systems from other manufacturers
• Single-unit packaging — order by junction count, not by carton minimums

Wire basket tray excels in high-density, high-change environments because cables rest in open mesh rather than enclosed conduit, but every branch and turn introduces a potential weak point for both load transfer and electrical continuity. The PWBPF4X8WH solves both: its formed-steel geometry distributes tensile and compressive forces across all three legs of the tee, and its conductive body ensures that fault currents from a downstream short have a continuous metallic return path to ground. This matters during commissioning — inspectors will verify bonding jumpers or, in the case of UL-classified fittings like this one, accept the fitting itself as the grounding conductor, eliminating the need for separate bonding hardware at every junction.

The powder-coat finish serves a dual purpose: it protects the underlying steel from oxidation in HVAC-conditioned spaces (where humidity swings can accelerate surface rust on bare metal), and it delivers the clean white aesthetic required in executive floors, hospital corridors, university labs, and anywhere pathways remain visible after installation. Unlike painted fittings that chip at bolt-hole edges during assembly, powder coating bonds at the molecular level and resists flaking under the mechanical stress of tightening hardware. Installers working in occupied spaces appreciate the finished appearance — no need to return for touch-up paint after cable pulls.

Compatibility extends beyond Panduit's own PW-series basket tray: the 4" width and 8" height dimensions match the de facto standard shared by most North American wire-basket manufacturers, and the bracket's bolt-hole pattern accommodates the M6 or 1/4"-20 hardware common to the category. The competitor part number WBT-R90-4X8WH cross-references directly, confirming drop-in interchangeability for retrofit projects where the original tray brand is unknown or discontinued. When you're expanding an existing pathway or replacing a damaged fitting during a maintenance window, dimensional consistency eliminates the need to modify adjacent tray sections or fabricate custom adapters — the PWBPF4X8WH bolts in and the job closes out on schedule.
