Master Lock S602 Large Portable Group Lockout Box with Key Window and Rewritable Tag

The Master Lock S602 is a large portable group lockout box engineered for demanding industrial lockout/tagout (LOTO) procedures. Built from 430-grade stainless steel, this group lock box is designed to withstand the toughest workplace environments while providing a centralized, secure location for managing multiple energy isolation points simultaneously.

Key Features:

• Clear, impact-resistant key window — a removable cup on the front creates a visible window so all participants can confirm keys are secured inside the box during a group lockout
• Rewritable tag included — use a permanent marker to document specific procedure or machine information directly on the tag; wipe clean with isopropyl alcohol and reuse as needed
• 430-grade stainless steel construction maximizes corrosion resistance for long-term durability in harsh conditions
• Flanged side design allows for easy application of individual locks by all authorized personnel
• Gasketed key slot guides keys securely into the removable cup
• Drain holes on the bottom prevent liquid accumulation inside the box
• Stackable design simplifies storage and makes transporting multiple boxes more efficient
• Hinged door with red finish for high-visibility identification in safety-critical environments
