Panduit MT350-M Stainless Steel Marker Plate and Tag
The Panduit MT350-M is a one-hole, 304 stainless steel marker plate designed for permanent cable and asset identification in environments where plastic labels would degrade — think industrial enclosures, outdoor cable trays, and high-temperature panel runs. Each piece measures 3.50" x 0.75" (overall), and the pack ships 1,000 pieces per carton, making it practical for large-scale labeling projects without mid-job restocking. The MT350-M (often searched as MT350 M) is part of Panduit's identification and labeling line, engineered for integration with their marker insertion and printing systems.
Overview
When plastic cable labels won't survive the environment — UV exposure, chemical wash-down, high heat, or physical abrasion — 304 stainless steel is the correct material choice. The MT350-M delivers a rectangle marker plate with a single mounting hole that allows permanent fastening to cables, conduit, panels, or equipment frames. At 19.1mm (0.75") wide and 3.50" long, it provides enough surface area for machine-printed text at readable sizes while staying narrow enough to fit standard cable bundles and marker insertion frames. This is the right pick when you need permanent metal identification markers that will outlast the installation itself.
Key Features
- 304 Stainless Steel Construction: Type 304 is the standard corrosion-resistant alloy for industrial labeling — resistant to most industrial solvents, humidity, and moderate chemical exposure. If your installation involves regular wash-down, salt air, or outdoor exposure, this eliminates the label replacement cycle that plagues adhesive plastic alternatives.
- 3.50" x 0.75" Rectangle Format: The 3.5-inch length accommodates multi-character alphanumeric strings at legible print sizes. The 0.75-inch width (19.1mm) is sized to fit standard marker insertion frames and cable tie-wrap channels without adding bulk to the bundle.
- Single Mounting Hole: The one-hole design allows the marker to be fastened with a screw, cable tie, or wire through the hole — giving you a physically secured label that won't shift or fall off under vibration or thermal cycling, which matters in motor control panels and mechanical rooms.
- Compatible with MLT-S, MIM, and PES400 Systems: The MT350-M is designed to work with Panduit's MLT-S cable tie mount, MIM marker insertion machine, and PES400 printing systems — meaning you can machine-print and insert at volume rather than hand-stamping individual tags. This is a meaningful throughput difference on large wire-tag jobs.
- 1,000 Pieces Per Package, 4,000 Per Carton: The 1,000-piece pack quantity is sized for project-scale use — a single package covers a medium-sized panel or cable run. The 4,000-piece carton suits contractors running multiple panels or ongoing service agreements. No per-piece overhead on procurement.
- RoHS Compliant: Meets RoHS directives, which is a procurement requirement for projects delivered into the EU and increasingly a standard clause in commercial construction and systems integration contracts in the US. Verifiable at the SKU level — not a blanket brand claim.
Integration and Compatibility
The MT350-M integrates directly with Panduit's marker insertion and printing ecosystem. Compatible systems listed in the evidence include the MLT-S cable tie mount system, MIM marker insertion machine, and PES400 label printer. If you're already running Panduit printing infrastructure, these tags load and print without adapter hardware. For installations requiring custom legend text or sequential numbering, the PES400 path is the production-ready option. Pair with appropriate cable ties and mounting hardware for the complete cable identification assembly.

Frequently Asked Questions
Q: What material is the MT350-M made from?
A: The MT350-M is made from Type 304 stainless steel — the standard corrosion-resistant alloy used in industrial identification applications.
Q: What are the dimensions of each marker tag?
A: Each marker measures 3.50 inches in length and 0.75 inches (19.1mm) in width, in a rectangular format with one mounting hole.
Q: What Panduit systems is the MT350-M compatible with?
A: The MT350-M is designed for use with the Panduit MLT-S cable tie mount system, MIM marker insertion machine, and PES400 printer.
Q: How many pieces are included per package?
A: Each package contains 1,000 marker plates. The full carton quantity is 4,000 pieces.
Q: Is the MT350-M RoHS compliant?
A: Yes, the MT350-M meets RoHS compliance standards as listed in the product specifications.
Q: Is this suitable for outdoor or wash-down environments?
A: The 304 stainless steel construction makes the MT350-M suitable for environments with humidity, moderate chemical exposure, and outdoor conditions where plastic labels would fail. It is not rated for submersion.
The MT350-M is the tag I spec when a project requires labels that have to outlast the installation — the 304 stainless steel construction and single-hole mounting design mean these aren't going anywhere once installed, and the 3.50" x 0.75" format gives enough print surface for multi-field legends without crowding the cable bundle.
Technical Highlights:
- 304 Stainless Steel: Resists corrosion, chemical exposure, and physical abrasion — where ABS or vinyl labels would crack or delaminate within a year in a wet mechanical room, these stay legible for the life of the installation.
- 1,000-Piece Pack / 4,000-Piece Carton: Practical pack sizing for project-scale work — a single 1,000-piece package handles a medium panel run; the 4,000-piece carton quantity keeps procurement simple on multi-panel jobs or service contracts.
- MLT-S / MIM / PES400 Compatibility: Machine-printing and insertion compatibility with Panduit's existing marker systems eliminates hand-stamping on large wire-tag jobs — the difference between 50 tags per hour and 500.
Deployment Considerations:
- These tags require a compatible Panduit printing or insertion system (MLT-S, MIM, or PES400) for machine production — if you're hand-stamping or using a non-Panduit printer, verify fit and legend transfer method before ordering at volume.
- The single hole is sized for mechanical fastening — screw, cable tie, or wire. It is not self-adhesive, so plan your attachment method into the installation labor estimate, particularly on high-density cable trays where per-tag time adds up.
Best deployment fit: industrial control panels, outdoor cable tray runs, and mechanical rooms where permanent, corrosion-resistant identification is a maintenance or compliance requirement — not a nice-to-have.
