Panduit FL50X50LG-AV Flexible Wiring Duct, 50x50mm Slotted Polypropylene, 32-Pack
Overview
The Panduit FL50X50LG-AV is a 1.97" x 1.97" (50 x 50 mm) flexible, slotted-sidewall wiring duct from the Panduct® line, engineered specifically for installations where rigid duct is impractical — control panel doors, articulating surfaces, and tight enclosure runs where you need to route or re-route conductors without cutting or removing terminations. Each piece is 19.7" (500 mm) long and ships in a package of 32, making it a practical buy for panel builders and integrators stocking up for a job. The FL50X50LG-AV (often searched as FL50X50LG AV) uses a one-piece open-finger design that lets you add or remove wires after termination without special tooling — a real time-saver during commissioning or field changes.
Key Features
- Flexible Polypropylene Construction: The duct flexes and bends to follow compound angles on panel doors or around obstacles — anywhere rigid PVC duct would crack or bind. Polypropylene also resists the cleaning chemicals common in industrial and food-adjacent environments.
- High Bond Acrylic Adhesive Option: The adhesive backing lets you position and secure the duct directly to control panel doors and surfaces where drilling or screwing is not an option. Eliminates the need for separate mounting hardware on smooth metal or powder-coated surfaces.
- Open-Finger Slotted Sidewall Design: Wires exit through the slots at any point along the duct length without requiring a dedicated exit point. Add conductors mid-run after termination without disturbing adjacent wiring — meaningful on dense PLC panels with frequent change orders.
- 50 x 50 mm Cross-Section (1.97" x 1.97"): Sized for moderate wire fill — right for I/O wiring runs, sensor cables, and low-voltage control conductors. Not the right choice for high-fill main power runs; use a larger cross-section duct for those.
- 500 mm (19.7") Length per Piece: At roughly half a meter each, 32 pieces cover approximately 16 meters (52.5 ft) of duct run — enough to outfit a full-size control panel or a row of smaller enclosures in a single order.
- UL 94 V-2 Flammability Rating: Meets the UL 94 V-2 self-extinguishing requirement. The duct will not sustain a flame after ignition is removed — required for most UL 508A panel shop builds and accepted in CE-marked equipment assemblies.
- RoHS, UL Recognized, CE, and BABA Compliant: RoHS compliance keeps the duct out of restricted-substance scope for EU export. UL Recognition satisfies most North American panel shop and inspection requirements. BABA (Buy American Build America) compliance qualifies this duct for federally funded infrastructure projects where domestic-content rules apply.
- Light Gray Color: Standard light gray matches the majority of North American and European panel interiors, keeping the installation visually clean without special ordering a color match.
Integration & Compatibility
The FL50X50LG-AV is designed to work within the broader Panduct® wiring duct ecosystem. It pairs with standard Panduit duct fittings, dividers, and covers sized for the 50 x 50 mm profile. For runs transitioning from flexible to rigid duct, use matching Panduct® rigid duct of the same cross-section to maintain a continuous, organized pathway. The adhesive mounting option is compatible with standard powder-coated and painted steel panel surfaces; surface prep (clean, dry, grease-free) is required for reliable adhesion. For cable management applications requiring larger fill capacity or higher flame ratings, evaluate Panduct® flexible duct in wider profiles or the rigid Panduct® series with UL 94 V-0 ratings. Review the full Panduit wiring duct and cable management catalog for compatible fittings and accessories. Integrators specifying duct for control panel enclosures or security system wiring should also cross-reference Panduit's wire management accessories for clips, ties, and separators that complement this duct profile. For broader panel wiring planning, a structured cabling and wire management guide can help optimize fill ratios and duct sizing across a full panel build.

Frequently Asked Questions
Q: Can I add or remove wires from the FL50X50LG-AV after termination without special tools?
A: Yes. The open-finger slotted sidewall design is specifically intended to allow wire addition and removal post-termination without any special tooling. This is one of the primary differentiators versus rigid closed-finger duct.
Q: What flammability rating does the FL50X50LG-AV carry, and is it acceptable for UL 508A panel shop builds?
A: The FL50X50LG-AV carries a UL 94 V-2 flammability rating, which is self-extinguishing. This meets the requirements for most UL 508A panel assemblies. If your application requires V-0 or V-1, you will need to select a different duct product with a higher flame rating.
Q: How much linear run does a 32-piece package of FL50X50LG-AV cover?
A: Each piece is 500 mm (0.5 m / 1.64 ft) long. A 32-piece package covers approximately 16 meters (52.5 ft) of duct run — sufficient for a full-size control panel or multiple smaller enclosures.
Q: Is the FL50X50LG-AV compliant with Buy American Build America (BABA) requirements for federally funded projects?
A: Yes. The FL50X50LG-AV is listed as BABA Compliant, making it eligible for use on federally funded infrastructure projects subject to domestic-content procurement requirements.
Q: What mounting options are available for the FL50X50LG-AV?
A: The FL50X50LG-AV includes a High Bond Acrylic Adhesive option for direct mounting to panel doors and surfaces where drilling or screwing is not practical. It is rated for wall mounting. Surface must be clean, dry, and grease-free for reliable adhesion.
Q: Is the FL50X50LG-AV RoHS compliant?
A: Yes. The FL50X50LG-AV meets RoHS compliance requirements, keeping it within restricted-substance regulations for EU and international applications.
The FL50X50LG-AV is one of those components that earns its keep in the field rather than on the spec sheet. The High Bond Acrylic Adhesive backing is the detail that matters most for panel door applications — if you've ever tried to run rigid duct on a hinged door, you know the limitations. This Panduct® flexible duct handles that problem cleanly, with the 50 x 50 mm cross-section giving you enough fill capacity for typical I/O and sensor wiring without over-sizing the run.
Technical Highlights:
- UL 94 V-2 Self-Extinguishing Rating: Meets the flame-spread requirement for UL 508A panel builds without needing to special-source a higher-rated material — V-2 covers the vast majority of commercial and industrial panel shop specifications.
- 500 mm Piece Length, 32-Pack: At 16 meters total per package, this buy quantity is sized for a meaningful panel project, not a single patch. The math works out cleanly for a standard 600mm x 400mm or 800mm x 600mm enclosure with multiple duct runs.
- BABA Compliance: Federally funded projects — infrastructure upgrades, transit authority control rooms, government facility automation — often require BABA-compliant materials. Having this documentation in the product listing avoids a specification substitution conversation late in the project.
Deployment Considerations:
- The adhesive mount requires a properly prepped surface. On panels with heavy silicone contamination or oil film from manufacturing, adhesion will fail. Clean with IPA before applying — this is not optional on industrial enclosures.
- UL 94 V-2 is self-extinguishing but not V-0. If your panel shop's build spec or customer spec calls for V-0 rated duct — common in some process control and power distribution applications — this product does not qualify. Verify the flame rating requirement before ordering.
The FL50X50LG-AV is the right call for security and automation panel builders working on control panel door wiring, articulating cable runs, and any enclosure section where the duct needs to flex rather than stay rigid — particularly on projects with federal funding where BABA documentation is a procurement requirement.
