The S602 Group Lock Box is made of 430-Grade stainless steel to withstand the toughest environments. The rugged construction offers enhanced design features, making this box stronger and easier to use. The S602 includes 19 total lockout holes, including one on the front latch for the operations lock. The box includes a removable cup that creates a clear, impact-resistant window on the front, allowing participants to see keys are secured inside the box during a group lockout. The S602 also includes a rewritable tag for specific procedure or machine information – use a permanent marker to write on the tag and wipe clean with isopropyl alcohol. The stackable design facilitates storage and simplifies transporting multiple boxes. Replacement removable key cups and rewritable tags are available.
