Designed to meet OSHA and NFPA standards, Justrite's safety cabinets are sturdily constructed of all-welded, 18-gauge, double-walled steel with 1.5" of insulating air space for fire resistance. High performance, self-latching doors close easily and securely for maximum protection under fire conditions. Fail-safe closing mechanism ensures three-point latching system works the first time, every time. Exclusive "spill-catcher" galvanized steel shelves catch incidental drips and adjust on 2.25" centers for versatile storage. Other extras include a leaktight 2" bottom sump, dual vents with flame arresters, four adjustable leveling feet, grounding connector and warning label. Fully painted inside and out with a durable lead-free epoxy/polyester powder paint for chemical resistance, each cabinet is backed by an exclusive Ten Year Warranty. FM approved.
