Panduit IMLTFC152S-C6L StrongHold Fully Coated 316L Stainless Steel Cable Tie, 20.5", 100-Pack

Overview

The Panduit IMLTFC152S-C6L is a 20.5-inch (521 mm) locking cable tie from the Panduit StrongHold line, engineered specifically for installations where standard nylon ties fail — corrosive process environments, outdoor cable runs, chemical plants, and refineries. The fully coated 316L stainless steel construction combines the corrosion resistance of marine-grade alloy with a black polymer coating that prevents direct metal-to-metal contact, protecting both the tie and the cable jacket from abrasion and galvanic interaction. Each pack contains 100 ties, with a 500-unit carton available for large-scale installs.

If you're specifying industrial cable ties for infrastructure that lives outdoors, near salt spray, or in chemical exposure zones, the material choice here is non-negotiable — 304 SS is adequate for mild environments, but 316L's molybdenum content is what holds up in chloride-heavy and acidic atmospheres where 304 begins to pit.

Key Features

• 316L Stainless Steel Core: The "L" grade (low carbon) minimizes carbide precipitation during fabrication, which directly preserves corrosion resistance at welded joints and formed areas. For long cable runs in refineries or coastal outdoor enclosures, this grade survives where standard 304 SS ties eventually develop surface rust and stress corrosion cracking.
• Full Polymer Coating, Black: The complete coating over the stainless core serves two functions — it cushions cable jackets against the metal's sharp edges (critical on plenum-rated or thin-wall data cables), and it eliminates the galvanic couple that occurs when bare SS contacts aluminum cable trays or copper conductors directly. Black coloring also provides UV absorption tolerance and blends with standard black cable jacket installations.
• 20.5-Inch (521 mm) Working Length: This longer format handles large bundle diameters — conduit groups, multiconductor power runs, and thick fiber bundles that shorter 8" or 11" ties can't cinch. Plan your bundle diameter against the usable loop length; the 521 mm total accommodates bundles up to roughly 150 mm (6") diameter with adequate tail for tensioning.
• Self-Locking Mechanism: The locking head is designed for tool-assisted tensioning using compatible Panduit installation tools (GS4MT-E, HTMT, PPTMT, ST2MT) — these apply controlled, consistent tension and cut the tail flush, which matters on safety-critical runs where a sharp protruding tail is a hazard or a snag point. Manual application is possible but results in inconsistent tension.
• UL Listed (File E56854): UL listing provides third-party verification of the tie's construction and material claims. For installations subject to NEC compliance review or commissioning sign-off by a third-party inspector, UL-listed hardware simplifies the paperwork trail. The listing number E56854 is verifiable directly through UL's database.
• Indoor/Outdoor Rated: Confirmed for both environments in the product specification. Outdoor rating paired with 316L SS and full coating means these are appropriate for exposed cable management on rooftop equipment, outdoor enclosures, security camera cabling runs on building exteriors, and process plant exterior tray work.
• Pack Quantity — 100 Units Per Pack, 500 Per Carton: The 100-unit pack size fits project-scale purchasing without committing to the 500-unit carton. For cable management projects with defined scope (a single rack row, one camera run, a panel bundle), the 100-pack matches consumption without leaving excess stock to degrade in storage.

Integration and Compatibility

The IMLTFC152S-C6L (often searched as IMLTFC152S C6L) is designed for use with Panduit's tool series: GS4MT-E, HTMT, PPTMT, and ST2MT installation guns. These tools are sold separately and are worth specifying on the same Panduit tools order if your team doesn't already have them — hand-tightening 316L SS ties to consistent tension is difficult, and tail cut quality affects both safety and aesthetics in finished cable management work.

Cross-reference part numbers from other manufacturers that this tie replaces or is compatible with include: 111-01513, 12810B, 12860B, S6420, and S6421. If you're replacing an existing inventory of competitor ties with this SKU, confirm the bundle diameter and minimum bend radius requirements match before substituting at scale.

For complete cable routing systems, pair these ties with appropriate cable tray and ladder rack — the fully coated SS ties won't abrade tray paint or create galvanic issues on aluminum tray systems.

Frequently Asked Questions

Q: What is the difference between the IMLTFC152S-C6L and a standard stainless steel cable tie?

A: The IMLTFC152S-C6L uses 316L stainless steel (not 304 SS) and adds a full black polymer coating over the metal. 316L's molybdenum content provides significantly better resistance to chloride-induced pitting and stress corrosion cracking — important in chemical plants, coastal environments, and anywhere salt spray or process chemicals are present. The full coating also protects cable jackets from abrasion and prevents galvanic corrosion when the tie contacts dissimilar metals like aluminum trays.

Q: What installation tools work with the IMLTFC152S-C6L?

A: Panduit specifies the GS4MT-E, HTMT, PPTMT, and ST2MT installation tools for this tie. These tools apply consistent, controlled tension and cut the tail flush — important on safety-critical or inspection-grade cable runs. Manual tensioning is possible but produces inconsistent results, especially with the stiffer 316L SS material.

Q: How many ties are included per package?

A: Each package contains 100 ties. The full carton contains 500 ties (5 packs). Order the carton quantity if you're stocking for ongoing maintenance use; the 100-pack is better matched to defined project scopes.

Q: Is the IMLTFC152S-C6L UL listed?

A: Yes. The IMLTFC152S-C6L meets UL listing requirements under file number E56854. This provides third-party verification of the construction and material claims, and simplifies compliance documentation for inspected installations.

Q: Can these cable ties be used outdoors?

A: Yes. The IMLTFC152S-C6L is rated for both indoor and outdoor use. The combination of 316L stainless steel, full polymer coating, and UL listing makes it appropriate for exposed outdoor cable management — rooftop runs, exterior enclosures, and process plant outdoor tray work.

Q: What bundle diameter can a 20.5-inch cable tie accommodate?

A: The 20.5-inch (521 mm) overall length provides enough working loop to handle bundles up to approximately 150 mm (6 inches) in diameter when accounting for the locking head and minimum tail length for proper tensioning. Verify your specific bundle diameter before ordering if you're near that upper limit.

The IMLTFC152S-C6L is the tie I specify when 304 SS or nylon isn't going to hold up and the job can't afford a re-tie six months later. The 316L grade with full polymer coating is a specific material combination — not just a marketing upgrade — and the 20.5-inch length covers the large-bundle scenarios that shorter ties simply can't handle.

Technical Highlights:

• 316L Grade (Low Carbon SS): The low-carbon formulation prevents carbide precipitation at formed and stressed areas of the tie, which is exactly where 304 SS begins to pit in chloride or acidic environments. For refineries, wastewater plants, or coastal outdoor runs, this is the correct alloy — not an overspec.
• Full Coating Over Metal Core: The black polymer jacket does real work: it cushions cable jackets (prevents insulation abrasion on multiconductor runs), breaks the galvanic couple against aluminum tray, and gives you a cleanly finished appearance on visible cable management. Bare SS ties cut jacket insulation on long-term vibrating runs.
• UL File E56854: Third-party listed, verifiable. On any project with a third-party commissioning inspector or NEC-compliance checklist, UL-listed cable management hardware gets waved through. Unlisted hardware gets questioned. Worth the spec decision.

Deployment Considerations:

• Budget for the compatible Panduit installation tool (GS4MT-E, HTMT, PPTMT, or ST2MT) on any job using these in volume. 316L SS is stiffer than nylon and harder to tension by hand to consistent torque — tool-applied tension is the right approach, especially on safety-critical tray runs or anywhere tail trimming quality is inspected.
• The 100-pack is the right procurement unit for project-specific work; the 500-unit carton is the stocking unit for maintenance shops. Don't order the carton for a one-time job — SS ties stored improperly (wet storage, contaminated bins) can develop surface oxidation on the coating edges before use.

Best fit: large-bundle cable management in chemical processing, coastal outdoor security camera infrastructure, or any industrial installation where the commissioning inspector will be checking both material certification and tie-installation quality on the finished cable runs.
