Panduit IMLT355H-Q StrongHold™ Heavy-Duty Stainless Steel Cable Tie

The Panduit IMLT355H-Q delivers industrial-grade cable management for installations where corrosion, temperature extremes, or physical abuse would destroy conventional polymer ties. Built from type 304 stainless steel and measuring 45.5 inches in length, this StrongHold™ tie secures large cable bundles in outdoor enclosures, coastal environments, chemical processing plants, wastewater facilities, and equipment rooms where NFPA 70 or local AHJ mandates metal ties. UL-listed under file E56854, the IMLT355H-Q meets NEC requirements for supporting power and communications wiring in commercial and industrial occupancies.

Key Features

Type 304 stainless steel construction resists rust, UV degradation, and temperature cycling from -80°F to +1000°F

45.5-inch length accommodates bundle diameters up to 14 inches — ideal for backbone fiber trunks, multipair copper runs, and industrial control wiring

0.010-inch material thickness provides high tensile strength while remaining flexible enough for hand installation with compatible Panduit tools

UL-listed (file E56854) for compliance with NEC Article 300.11 support requirements and local fire marshal inspections

Ships in 25-count packages (125 per carton) with metallic finish that blends into gray or silver cable tray and ladder rack

Type 304 stainless steel offers the most common balance of corrosion resistance and cost for security and IT infrastructure. While marine environments or direct chemical exposure may call for 316-grade alloys, 304 SS handles rain, humidity, temperature swings, and incidental contact with cleaning agents in parking structures, rooftop installations, and industrial MDF/IDF rooms. The IMLT355H-Q's 0.010-inch thickness sits in Panduit's heavy-duty class — thicker than light-duty ties used for patch cord dressing, robust enough to support vertical cable runs and outdoor conduit straps without cutting into jacketing under load.

The 45.5-inch working length makes this tie the go-to choice when you're bundling 50+ Cat6A cables in a data center hot aisle, strapping fiber entrance cables to building steel, or securing multi-conductor control wire in a factory automation cabinet. Standard 8- or 14-inch ties require daisy-chaining or won't close around the bundle; the IMLT355H-Q wraps once and locks, eliminating the need for multiple ties and reducing both material cost and installation time. Integrate it with Panduit's GS4MT-E mount bases, PPTMT push-mount anchors, ST2MT screw ties, HTMT hook-and-loop mounts, or PBTMT push-button bases to create Code-compliant support assemblies on cable tray, threaded rod, or J-hooks.

Installations subject to fire marshal or electrical inspector review benefit from the UL listing under file E56854. This third-party certification confirms the tie meets flammability, load-bearing, and materials standards required by NEC and adopted building codes — critical when AHJs red-tag jobs for using uncertified hardware. The metallic finish also satisfies aesthetic requirements in exposed-ceiling commercial spaces where black polymer ties stand out against aluminum tray or galvanized support hardware.

The IMLT355H-Q ships in 25-count hang-sell packages, with five packages per 125-count carton. This packaging lets you stock a small quantity on the service truck for emergency repairs while bulk-ordering cartons for new construction or retrofit projects. Pair with Panduit's GS4MT-E edge-mount clips for tool-free attachment to cable tray flanges, or use ST2MT screw-mount ties when anchoring to wood studs, ladder rack rungs, or equipment chassis. For outdoor camera pole installations, wrap the IMLT355H-Q around conduit and EMT before securing to the pole with U-bolts — the stainless construction won't rust or weaken under years of sun and rain exposure.
