Panduit MT350W17-D-4HL 304 SS 4-Hole Marker Plate

Panduit MT350W17-D-4HL Marker Plate with Tag

The Panduit MT350W17-D-4HL is a stainless steel marker plate and tag designed for permanent asset identification in demanding commercial environments. Constructed from corrosion-resistant Type 304 stainless steel, this 3.50" × 1.73" plate provides long-term durability in outdoor enclosures, industrial facilities, and harsh-environment datacenter deployments where galvanized or aluminum tags would corrode. The 4-hole mounting pattern integrates with Panduit MLT-S, MIM, and PES400 cable tie and marker systems, creating a unified identification standard across multi-site installations. RoHS-compliant and packaged in 500-unit quantities, this marker plate supports the labeling requirements of campus builds, critical infrastructure projects, and compliance-driven asset management programs.

Key Features

• Type 304 Stainless Steel Construction: Resists corrosion in outdoor, coastal, and chemical-exposure environments where plated steel or aluminum markers fail within months.
• 4-Hole Mounting Design: Secures to cable bundles, equipment chassis, and enclosure walls using Panduit MLT-S stainless steel cable ties or standard mounting hardware.
• 3.50" × 1.73" Dimensions: Provides sufficient marking area for asset tags, QR codes, or engraved identifiers while remaining compact enough for crowded patch panels and high-density racks.
• MLT-S / MIM / PES400 System Compatibility: Integrates with Panduit's stainless steel tie, metal identifier mount, and pre-printed label ecosystems for consistent asset tracking across cable plant and equipment.
• RoHS Compliance: Meets European and California material restrictions for installations in regulated facilities, government projects, and equipment exported to RoHS-enforcement jurisdictions.
• 500-Unit Packaging: Bulk quantity supports datacenter builds, campus network deployments, and integrator stock programs without frequent reordering.

Type 304 stainless steel is the industry-standard alloy for identification hardware in non-marine corrosive environments. Its chromium-nickel composition forms a passive oxide layer that self-heals when scratched, maintaining legibility and structural integrity through years of UV exposure, temperature cycling, and chemical splash. Unlike powder-coated aluminum or vinyl-laminated tags that degrade under prolonged outdoor service, this marker plate retains dimensional stability and surface finish in rooftop camera installations, parking structure access control systems, and perimeter intrusion detection networks. The 4-hole pattern distributes mechanical load across the plate, preventing stress concentration that causes single-hole tags to tear free under cable bundle tension or wind loading. When paired with Panduit's MLT-S stainless steel cable ties (sold separately), the assembly creates a corrosion-matched system with no galvanic mismatch or differential expansion—critical for installations subject to NFPA 70 (NEC) Article 110.14 requirements for identified circuits and equipment.

Commercial security integrators face increasing compliance pressure to document asset provenance, maintenance history, and inspection status at the equipment level. The MT350W17-D-4HL provides a permanent substrate for engraved serial numbers, laser-etched QR codes, or adhesive asset labels that link physical devices to CMMS platforms, warranty databases, and configuration management systems. The 3.50" × 1.73" footprint accommodates standard 1" × 2.5" barcode labels with room for human-readable text, or supports direct metal engraving via rotary, fiber-laser, or electrochemical etching processes. In datacenter environments, these plates attach to cable ladder rungs, overhead bus duct, and PDU input feeders to satisfy BICSI DCDC certification requirements for labeled pathways. In building management systems, they mark valve actuators, damper controllers, and fire alarm initiating devices per local AHJ interpretation of NFPA 72 and IBC Chapter 9. The bulk 500-count packaging aligns with the scale of multi-building campus projects, new construction handoffs, and integrator perpetual inventory programs where per-piece ordering creates procurement bottlenecks.

Panduit's stainless steel marker plate integrates into lifecycle asset management workflows that extend beyond initial installation. Facilities teams use these plates to track calibration intervals on surveillance cameras, document firmware versions on access controllers, and record commissioning dates on network switches—data that remains readable through equipment service life and supports decommissioning audits when systems reach end-of-support. The RoHS compliance matters for integrators bidding federal contracts, California Title 24 projects, and EU-market equipment exports where non-compliant components void certifications. For deployments in salt-air coastal zones, chemical plants, or food processing facilities, the Type 304 alloy specification ensures the identification system doesn't become the weak link that forces premature replacement or creates safety hazards from corroded, illegible tags during emergency response.
