Panduit MMP350-C 304 Stainless Steel Marker Plate with Tag

The Panduit MMP350-C delivers permanent asset identification in environments where plastic tags fail. Stamped from 304 stainless steel, these 3.5" × 0.75" marker plates resist corrosion, UV degradation, and chemical exposure across power distribution centers, industrial controls, and outdoor telecom installations. The raised feed slot accepts standard stainless cable ties without pre-threading, cutting install time on high-density cable runs and equipment racks. Each plate accommodates three lines of engraved or stamped text, maintaining legibility through decades of service. Sold in 100-piece packages with cartons of 1,000 for volume deployments.

Key Features

304 stainless steel construction resists corrosion in coastal, chemical, and outdoor environments

3.5" × 0.75" footprint balances visibility with compact mounting on conduit and equipment

Raised feed slot simplifies cable tie installation—no pre-threading or alignment required

Three-line text capacity supports detailed asset coding (circuit ID, destination, install date)

100-pack quantity matches typical rack or zone deployment scale

RoHS compliant for projects requiring environmental certifications

Type 304 stainless steel delivers passive corrosion resistance through chromium oxide surface formation, maintaining structural integrity and text legibility in NEMA 3R enclosures, chemical processing areas, and marine-proximate installations where galvanized or coated steel fails within months. The natural mill finish eliminates paint or coating that chips under thermal cycling or mechanical abrasion. The raised feed slot design—a 0.125" lip along the plate edge—guides standard MLT-S or MIM series stainless cable ties into position without the pre-bending or alignment step required by flat plates, reducing per-tag install time from 30 seconds to under 10 in high-volume runs. Material thickness of 0.020" provides rigidity for hand-stamping or engraving without buckling, while remaining thin enough for tight-clearance conduit mounts.

These plates integrate into Panduit's stainless identification ecosystem: pair with MLT-S ladder-style or MIM ball-lock cable ties for tool-free attachment to 1/2" – 4" conduit, cable bundles, valve stems, or equipment handles. Common deployment patterns include utility metering cabinets (circuit-level identification), chemical plant instrumentation (valve and sensor tagging), telecom outdoor equipment (fiber splice enclosure labeling), and transportation infrastructure (signal cabinet wire coding). The 3.5" length accommodates engraving formats like "480V-L1 / MDP-A / 03-2026" across three lines using rotary or laser engravers, or hand-stamping with 1/4" character sets. Competitor cross-reference to Brady ID1009, HellermannTyton SSID100 series, and Thomas & Betts equivalents eases spec-matching on retrofit projects.

RoHS compliance meets municipal and federal procurement requirements for lead-free components in public infrastructure projects. The 100-piece package quantity aligns with typical single-rack or single-building-floor deployments, while the 1,000-piece carton option supports campus-wide standardization programs. Unlike adhesive labels that lift in temperature swings or printed sleeves that fade under UV, stamped stainless plates maintain identification integrity for the full lifecycle of long-service infrastructure—20+ years in power distribution, telecom, and industrial control applications where asset tracking directly impacts safety and maintenance efficiency.
