Panduit MLTFC3.4S-CP316 Pan-Steel® MLT Fully Coated Cable Tie

The Panduit MLTFC3.4S-CP316 delivers 316 stainless steel strength with full polyester coating for cable management in corrosive, high-moisture, and temperature-extreme environments. This 12.2-inch MLT tie combines the corrosion resistance of marine-grade 316 SS with a protective polymer jacket that prevents galvanic reaction with aluminum cable trays and eliminates sharp edges that can damage jacketing during pulls or vibration. Self-locking head design locks at any point along the 3.4mm-wide body, letting you right-size bundles from quarter-inch patch cords to 3-inch conduit clusters without pre-measuring or cutting.

Key Features

316 stainless steel construction resists pitting and crevice corrosion in marine, chemical processing, and coastal installations where 304-grade ties fail

Full polyester coating eliminates metal-on-metal contact with cable trays, preventing galvanic corrosion on aluminum infrastructure

Self-locking head engages at any length along the tie body—no need to cinch to a specific position or trim excess before locking

12.2-inch length handles bundle diameters up to 3 inches, covering everything from single Cat6A runs to multi-cable vertical riser bundles

Black polyester finish provides UV resistance and hides dirt accumulation in dusty industrial and outdoor environments

Meets SAE AS23190/3 aerospace standard for tensile strength and temperature cycling, ensuring reliability in mission-critical telecom and power distribution

100-pack quantity suits mid-size projects; 500-piece carton volume supports campus buildouts and recurring maintenance stock

316 stainless steel's molybdenum content makes this tie the correct choice for any environment where chlorides, sulfates, or salt spray would degrade 304-grade stainless or nylon ties within months. Wastewater treatment control panels, seaside cell tower cable management, chemical plant instrumentation runs, and food processing facility power distribution all demand 316's crevice-corrosion resistance. The full polyester coating adds a second corrosion barrier while solving the galvanic incompatibility problem that arises when bare stainless contacts aluminum ladder rack—a common issue in datacenters and industrial facilities where mixed-metal infrastructure is standard. The smooth polymer jacket also protects cable insulation from abrasion during bundle tensioning and prevents the sharp-edge cuts that bare stainless ties can inflict on plenum-rated jacketing.

The self-locking head is a one-hand operation: thread the tail through the head, pull to desired tension, and the internal pawl locks automatically. Unlike ball-lock designs that require specific insertion depth or screw-style ties that need tools, the MLT mechanism works at any engagement point along the serrated body. This speeds installation when you're working off a ladder or in a cramped rack where you can't see the tie clearly, and it eliminates the pre-cut step required by fixed-length ties. Maximum bundle diameter is 3 inches at the 12.2-inch length, but you're not penalized for smaller bundles—lock it at 1 inch if that's what the run requires, and the excess tail simply extends beyond the head without compromising hold strength.

SAE AS23190/3 compliance certifies this tie for aerospace applications, which translates to real-world reliability in temperature-cycled outdoor telecom cabinets, high-vibration industrial control panels, and transit system cable management where failure isn't an option. The standard mandates minimum tensile strength, UV stability, and temperature range testing that exceeds typical commercial cable tie specs. For integrators working on projects with formal standards compliance requirements—military installations, FAA tower sites, nuclear facility I&C upgrades—the AS23190/3 callout satisfies procurement and inspection checklists without requiring separate qualification testing.
