Panduit PWBDW4WH Cable Tray Divider Wall 4-Inch Height White

Overview

The Panduit PWBDW4WH is a 4-inch-high powder-coated steel divider wall designed for use with overhead wire basket cable tray systems. Each package ships with two 63-inch lengths, providing enough coverage for a standard 10-foot basket pathway section in a single order. If you're running mixed copper, fiber optic, and power cabling in a shared tray, this divider is the hardware that keeps those paths separated — reducing crosstalk risk, maintaining bend radius control, and satisfying inspectors who want to see physical segregation between power and data runs.

Key Features

• 4-Inch Wall Height: At 4 inches, this divider provides meaningful vertical separation between cable categories within the tray — adequate for most enterprise structured cabling and low-voltage power runs sharing a common basket pathway. If you need greater separation, a taller wall variant is the right call.
• Two 63-Inch Pieces Per Package: Each pack covers exactly 10 linear feet of basket tray, which maps cleanly to standard 10-foot pathway sections. Plan your run length upfront — you'll need one PWBDW4WH per 10 feet of divided pathway.
• Powder-Coated Steel Construction: Steel with a powder-coat finish delivers the structural rigidity to stay vertical under cable load and resist corrosion in plenum or light industrial environments. This isn't a plastic insert — it holds its profile over time, even with dense cable fill.
• White Finish: Matches white wire basket tray systems, which are common in open-ceiling commercial interiors. If your tray is a different color, Panduit offers this divider in other finishes — verify your tray color before ordering.
• UL Classified for Equipment Grounding Conductor Use: The PWBDW4WH meets UL requirements under NEC Sections 392.3(C) and 392.7(B), meaning the tray system can serve as an equipment grounding conductor path — relevant for inspections and code compliance on commercial builds.
• Multi-Standard Compliance: Meets CAN/CSA-C22.2 No.126.1-02, NEMA VE 1-2002, and ANSI/NFPA 70. If your project requires documentation of NEC or Canadian electrical code compliance, these certifications are on record and verifiable.
• Designed for Copper, Fiber, and Power Cable Separation: The primary use case is separating cable categories in a shared overhead tray — keeping fiber away from copper, or low-voltage data away from AC power runs. Physical separation at the tray level is a cleaner solution than relying solely on shielding or conduit.

Integration & Compatibility

The PWBDW4WH is engineered specifically for Panduit's overhead wire basket cable tray routing systems. It installs into the basket's pathway sections and is dimensioned to match Panduit's standard basket widths. Competitor parts DIVIDER4WH and COTF105KITWH are listed as cross-references — if you're replacing an existing divider in a non-Panduit basket, verify basket inner dimensions before ordering. The 63-inch piece length is fixed, so cutting may be required for non-standard section lengths.

Frequently Asked Questions

Q: How much linear tray coverage does one package of PWBDW4WH provide?

A: One package includes two 63-inch divider wall pieces, covering a total of 10 linear feet — matching a standard 10-foot basket pathway section.

Q: What cable types is the PWBDW4WH designed to separate?

A: It is designed to provide separation for copper, fiber optic, and power cables running within a shared overhead wire basket cable tray system.

Q: Is the PWBDW4WH compliant with NEC requirements?

A: Yes. It is UL Classified for suitability as an Equipment Grounding Conductor per NEC Sections 392.3(C) and 392.7(B), and meets ANSI/NFPA 70, NEMA VE 1-2002, and CAN/CSA-C22.2 No.126.1-02.

Q: What is the material and finish of the PWBDW4WH?

A: The divider wall is constructed from steel with a white powder-coat finish, providing structural rigidity and corrosion resistance suitable for commercial plenum and light industrial environments.

Q: Will this divider work with non-Panduit wire basket trays?

A: The PWBDW4WH is designed for Panduit's overhead wire basket routing system. Cross-reference part numbers (DIVIDER4WH, COTF105KITWH) suggest some interoperability, but you should verify basket inner dimensions before ordering for use in a competing tray system.

The PWBDW4WH is the piece most installers overlook when speccing a wire basket tray system — and the one that causes the most inspection headaches when it's absent. The 4-inch powder-coated steel wall is specifically UL Classified for use as an Equipment Grounding Conductor under NEC 392.3(C) and 392.7(B), which matters the moment an AHJ starts asking for documentation on your mixed-cable overhead runs.

Technical Highlights:

• Two 63-inch pieces per package: Maps to one 10-foot basket section per SKU — straightforward to quantity-plan by section count. No partial-coverage math required if your run is in 10-foot increments.
• Powder-coated steel construction: Maintains vertical profile under cable load without creeping or deflecting. Plastic alternatives deform over time, especially in warm plenum spaces — steel holds its geometry.
• Multi-standard compliance (UL/NEMA VE 1-2002/CSA/NFPA 70): Covers both US and Canadian code requirements in a single SKU, useful on cross-border projects or facilities with mixed inspection authorities.

Deployment Considerations:

• Each piece is 63 inches fixed-length — for runs that aren't clean multiples of 10 feet, you'll need to cut to fit. Have a metal shear or angle grinder on site for trimming.
• White finish matches Panduit's white basket tray line. If your installed tray is galvanized or a different color, the color mismatch will be visible in open-ceiling environments — verify tray finish before ordering at scale.

The PWBDW4WH is the right call on any commercial build where copper data and AC power share an overhead basket tray and the AHJ requires documented physical segregation — data centers, healthcare facilities, and open-office structured cabling deployments with exposed ceiling infrastructure.
