Panduit FWR-C Panduct Wire Retainer and Labeling Accessory
Overview
The Panduit FWR-C is a PVC wire retainer and labeling device engineered specifically for Panduct® Type F and HN wiring duct. Sold in 100-piece packs, the FWR-C drops into duct channels ranging from 1.50" to 4.00" wide, securing cable bundles in place and providing a discrete labeling surface — two functions from a single, snap-in component that eliminates the need for separate tie-down and marker hardware.
At 3.88" in overall length and 0.70" (17.8 mm) in width, each retainer fits cleanly inside standard duct profiles without obstructing wire routing or creating pressure points on insulation. The dark beige PVC color matches Panduit® duct aesthetics, keeping panel and enclosure builds visually consistent.
Key Features
- Dual-function design (retention + labeling): Each FWR-C acts as both a cable retainer and a labeling point inside the duct. In dense panel builds where dozens of conductors share a single duct run, this means you can identify circuit segments at the duct without pulling wires out or affixing external markers — fewer labor steps per termination row.
- Compatible with 1.50"–4.00" Panduct® duct width: A single SKU covers the full range of Type F and HN duct widths used in most commercial and industrial panel builds. You don't need to stock separate retainer variants for different duct sizes on the same job.
- PVC construction: PVC handles the thermal and chemical environment of typical electrical enclosures — resistant to moisture, cleaning solvents common in industrial settings, and the heat generated by densely packed conductors. It won't become brittle or crack under normal panel operating conditions.
- 3.88" overall length: Long enough to bridge across the duct channel and seat securely without relying on adhesive or fasteners — retention is purely mechanical, which means re-routing wires later doesn't leave adhesive residue or require replacing damaged components.
- Dark beige color matched to Panduct® Type F and HN duct: Visually consistent with the duct system, so finished panels look intentional. In customer-facing or inspection-ready installations this matters — mismatched accessory colors signal a non-standard build to auditors and end-users alike.
- 100-piece packaging (FWR-C, often searched as FWR C): The standard package quantity of 100 aligns with how panel builders consume retainers — by the duct run, not one at a time. A carton contains 1,000 pieces for volume project pricing, keeping per-unit cost predictable across multi-panel contracts.
- Replaces competitor references DM1, DM2, TR1-E: If you're converting an existing panel design spec that calls out DM1, DM2, or TR1-E retainers, the FWR-C is the documented cross-reference — no re-engineering the layout, just swap the BOM line.
Integration and Compatibility
The FWR-C is designed exclusively for Panduit® Panduct Type F and HN duct — the two most common duct profiles found in commercial electrical panels, industrial control enclosures, and structured cabling builds. It does not require tools for installation; retainers snap into position along the duct channel.
For projects involving wire routing and cable management infrastructure, the FWR-C pairs naturally with the full Panduct duct system: Type F duct for standard panel wiring, HN duct for higher-fill or finger-duct applications. When combined with Panduit duct covers and duct connectors, retainer placement and labeling become part of a consistent, repeatable build process rather than a field improvisation.
Panel builders specifying network enclosures or industrial control cabinets will find the FWR-C compatible across the 1.50"–4.00" duct width range, covering virtually all standard duct sizes in a single line item on the BOM. For broader cable pathway planning, consult a cable management planning guide to size duct fill rates correctly before specifying retainer density.

Frequently Asked Questions
Q: What duct types and widths is the FWR-C compatible with?
A: The FWR-C is designed for Panduct® Type F and HN wiring duct with channel widths from 1.50" to 4.00". It is not documented for use with other duct profile families.
Q: How many retainers come in a package, and is a larger quantity available?
A: The standard sell unit is 100 pieces per package (FWR-C). A full carton contains 1,000 pieces for volume procurement.
Q: Does the FWR-C cross-reference any competitor part numbers?
A: Yes — the FWR-C is documented as a cross-reference for DM1, DM2, and TR1-E. If your existing panel spec calls out any of those part numbers, the FWR-C is the direct Panduit equivalent.
Q: What material is the FWR-C made from, and what is the color?
A: The FWR-C is molded from PVC and is dark beige in color, matching standard Panduct® Type F and HN duct aesthetics for a consistent panel appearance.
Q: What are the physical dimensions of the FWR-C retainer?
A: Each retainer measures 3.88" in overall length and 0.70" (17.8 mm) in overall width.
Q: Does the FWR-C require any tools or adhesives to install?
A: No — the FWR-C is a mechanical snap-in component designed to seat in the duct channel without tools, fasteners, or adhesive. This allows wire re-routing later without leaving residue or damaging the component.
The Panduit FWR-C is a component I recommend specifying at the BOM stage rather than sourcing as a field afterthought. The documented 1.50"–4.00" duct width compatibility means a single line item covers the full range of Panduct® Type F and HN duct sizes on a panel build — no variant proliferation, no last-minute substitutions when the wrong size shows up on the job.
Technical Highlights:
- PVC construction: Holds up to the thermal cycling and cleaning solvents typical inside commercial and industrial enclosures — more durable over time than polystyrene alternatives that become brittle in warm environments.
- 3.88" mechanical retention length: Seats across the duct channel without adhesive — re-routing conductors later is clean, no residue, no component replacement needed.
- 100-piece pack / 1,000-piece carton: Aligns with actual panel-build consumption patterns; ordering by the carton (1,000 pcs) brings per-unit cost down significantly on multi-panel contracts.
Deployment Considerations:
- The FWR-C is rated for Panduct® Type F and HN duct only — confirm your duct profile before ordering. Using it with non-Panduct duct systems is outside the documented application and may result in poor retention.
- At 0.70" wide per retainer, plan your retainer spacing based on duct fill percentage — over-placed retainers in a heavily loaded duct can create localized pressure on insulation. Follow Panduct fill rate guidelines for the duct size in use.
For production panel shops building commercial security, BAS, or industrial control enclosures with Panduct infrastructure, the FWR-C eliminates a common two-SKU (retainer + label) workflow and keeps the finished build visually consistent — the right call on repeat panel programs where labor efficiency compounds across units.
