Panduit FS6X4BL6 Solid Wall PVC Base Wiring Duct
Overview
The Panduit FS6X4BL6 is a 6-inch-wide by 4-inch-tall solid-wall PVC wiring duct designed for cable management installations where full enclosure, fire safety compliance, and a clean finished appearance are all non-negotiable. At 6 feet (1.83 m) per length, it belongs to the Panduct® line and ships in packs of 6 — right-sized for panel rooms, equipment racks, and structured cabling runs in commercial and industrial environments. The solid-wall construction completely encloses cable bundles, eliminating the exposed-slot look of slotted duct and preventing accidental contact or snagging during future add/move/change work. Cover is sold separately — confirm you have the matching cover part on your BOM before ordering.
Key Features
- Solid Wall Enclosure: Unlike slotted duct, the fully closed profile protects cables from physical contact, dust accumulation, and tampering. Essential in food processing, clean rooms, or anywhere janitorial chemicals or debris are a concern.
- UL 94 V-0 Flammability Rating: V-0 is the most stringent UL 94 burn classification — self-extinguishing with no dripping flaming particles. In a panel room or data closet, that rating is often a code requirement, not just a preference.
- Lead-Free PVC Construction: RoHS compliance is built into the material, not a post-production claim. This matters for projects subject to EU RoHS directives or domestic procurement rules — no additional documentation gymnastics required.
- 6.25" x 4.15" Cross Section (158.8 mm x 105.4 mm): The interior cross-section accommodates high-density cable bundles typical of 19-inch rack environments or multi-circuit control panel wiring. Size up front — retro-fitting larger duct after cables are pulled is expensive.
- UL Recognized, CE Compliant, BABA Compliant: Covers domestic federal procurement (Buy American/Build America), EU installations, and UL-listed panel builds in a single SKU. For government or institutional projects, BABA compliance alone can determine bid eligibility.
- Continuous-Use Rated to 122°F (50°C): The UL recognized temperature rating means it holds its form and fire-safety properties in warm equipment rooms without derating. Industrial environments with ambient heat loads are within spec.
- Pack of 6 / Carton of 60: The 6-piece pack matches a typical single-run or small panel installation. The 60-piece carton quantity means larger projects can reduce per-unit cost without custom ordering.
Integration & Compatibility
The FS6X4BL6 is a base duct — the cover is a separate line item (sold individually). Verify the matching Panduit cover part number before finalizing your order. The duct mounts to standard back panels, DIN rails, or wall surfaces using Panduit's standard duct mounting hardware. The 6" width is compatible with the Panduit Panduct® accessory ecosystem including inside corners, outside corners, tees, and reducers, making it practical to route complex paths without field-fabricated miters.

Frequently Asked Questions
Q: Does the FS6X4BL6 include a cover?
A: No — the cover is sold separately. The FS6X4BL6 is a base duct only. Order the appropriate Panduit Panduct cover part number to complete the installation.
Q: What flammability rating does the FS6X4BL6 carry?
A: UL 94 V-0 — the highest UL 94 classification, meaning the material self-extinguishes and does not produce dripping flaming particles. This is typically required for panel and enclosure installations under NEC and UL 508A.
Q: Is the FS6X4BL6 RoHS compliant?
A: Yes. The FS6X4BL6 uses lead-free PVC and meets RoHS, CE, UL Recognized, and BABA (Buy American/Build America) standards.
Q: What are the actual interior dimensions of the FS6X4BL6?
A: The overall cross-section is 6.25 inches wide (158.8 mm) by 4.15 inches tall (105.4 mm), with an overall length of 6 feet (1.83 m) per section.
Q: What is the maximum operating temperature for the FS6X4BL6?
A: UL recognized continuous-use temperature up to 122°F (50°C), suitable for warm equipment rooms and industrial control environments.
Q: How many pieces come in a package of FS6X4BL6?
A: Each package contains 6 duct sections. The full carton contains 60 pieces (10 packages).
The FS6X4BL6 is the duct I spec when a solid-wall run is a hard requirement — specifically because of that UL 94 V-0 rating and the 122°F continuous-use ceiling. In panel rooms where you have VFDs, power supplies, or high-density switching gear generating real ambient heat, a duct that can't hold its fire classification under load is a liability. The FS6X4BL6 holds both.
Technical Highlights:
- UL 94 V-0 / 122°F Continuous Use: Self-extinguishing, no flaming drip — passes the burn test that NEC panel enclosure builds actually require. The 50°C ceiling means it won't deform in hot gear rooms.
- 6.25" x 4.15" Cross Section: That 158.8 mm x 105.4 mm profile is wide enough to handle high-count cable bundles typical in 19" rack side-channel routing without jamming terminations.
- BABA + RoHS + CE + UL Recognized in a Single SKU: Four compliance marks out of the box means one less RFI response on government bids. Lead-free PVC satisfies RoHS at the material level — not a self-declaration.
Deployment Considerations:
- The cover is NOT included — this is a base duct only. Missing the cover part on a government job with BABA requirements means a non-compliant finished assembly. Pull the cover part number before the PO goes out.
- Pack quantity is 6 sections × 6 ft = 36 linear feet per pack. Map your run lengths before ordering to avoid short-shipping a job — partial sections don't ship from most distributors.
Best fit for UL 508A industrial control panel builds and government facility structured cabling projects where BABA compliance is a bid condition and V-0 fire rating is an inspector checkpoint — not an optional upgrade.
