Maximize chemical safety compliance without sacrificing valuable floor space with the Marketlab Piggyback Safety Cabinet. Engineered for high-density flammable liquid storage, this heavy-duty cabinet is specifically designed to stack directly on top of standard 30-gallon or 45-gallon safety cabinets, or to rest securely on laboratory countertops. Built from 18-gauge double-walled steel with 1.5 inches of insulating air space, it features dual 2-inch flame arrester vents, a 2-inch leakproof containment sump, and self-latching manual doors with a three-point fail-safe system to protect critical environments from fire hazards.
