Panduit PWBPF2X18BL Wire Basket Tee-Intersection Bracket
The Panduit PWBPF2X18BL solves the structural and grounding challenge at every T-intersection in wire basket cable tray installations. When three runs of 2-inch-height, 18-inch-width wire basket meet at a junction, this powder-coated steel bracket locks the geometry, transfers load across all three legs, and maintains continuous UL-classified grounding per NEC 392.7(B). Designed for data centers, telecom spaces, and industrial facilities where wire basket supports high-density low-voltage cabling and grounding path integrity is a code requirement, not an option.
Key Features
- UL Classified equipment grounding conductor per NEC 392.3(C) and 392.7(B) — satisfies Authority Having Jurisdiction sign-off on bonding continuity
- Engineered for 2" basket height × 18" width tee intersections — precise fit eliminates racking and maintains alignment under load
- Powder-coated steel construction — corrosion resistance in mechanical rooms, above-ceiling plenums, and humid environments
- Single-piece design — no assembly required, installs faster than field-fabricated junction reinforcements
- Competitor cross-reference WBT-R90-2X18BL — drop-in replacement for existing Panduit wire basket systems
Wire basket cable tray excels at ventilation and accessibility, but junctions concentrate stress. At every tee intersection, the perpendicular run transfers vertical load and lateral pull to two opposing legs. Without proper bracing, the joint racks open, baskets sag, and the grounding path through metal-to-metal contact degrades. The PWBPF2X18BL bracket clamps all three basket rails at the junction point, distributing load evenly and maintaining the steel-to-steel bond required for the tray system to function as an equipment grounding conductor. The powder-coat finish protects against oxidation that increases contact resistance, ensuring long-term code compliance in environments where humidity, temperature swings, or chemical exposure accelerate corrosion on bare or zinc-plated hardware.
Install the bracket where a perpendicular wire basket run terminates into a through-run — typical layouts include branch circuits feeding equipment rows from a main trunk, elevator shaft risers connecting to floor-level distribution pathways, or cross-aisle ties in server farms. The 18-inch width sizing matches Panduit's standard wire basket catalog for medium-density cable fills (approximately 150–250 low-voltage cables depending on bundle diameter and fill ratio per NEC 392.22). Pair with Panduit's wire basket straight sections, radius elbows, and drop brackets for a complete overhead pathway system that meets NEC Article 392 and supports structured cabling per TIA-568 or industrial control per IEC 61537. Mounting hardware and attachment method depend on your building structure — the bracket itself handles the tray-to-tray joint; ceiling attachment is separate (threaded rod, trapeze hangers, or beam clamps per your AHJ and seismic zone).
UL classification as an equipment grounding conductor separates spec-grade wire basket hardware from generic welded-wire products. NEC 392.7(B) permits cable tray to serve as the grounding path for circuits it supports only when every component in the metallic run is listed or classified for that use and installed per manufacturer instructions. Field inspectors verify listing marks at joints and fittings because a single non-listed splice breaks grounding continuity for the entire run. The PWBPF2X18BL carries that UL mark, closing the compliance gap at every tee junction and ensuring your installation passes rough-in inspection without rework or supplemental bonding jumpers.
