Optimize Flammable Liquids Storage with the Justrite 17G Flammable Safety Cabinet, Sure-Grip® EX Piggyback – 891720:

Elevate safety and efficiency with the Justrite 17G Sure-Grip® EX Piggyback Safety Cabinet, model 891720, meticulously designed to enhance the storage and segregation of flammable liquids in laboratory, construction, or engineering settings. Boasting exterior dimensions of 24 in H x 43 in W x 18 in D (610 mm H x 1092 mm W x 457 mm D), this cabinet offers a remarkable solution to limited floor space, enabling a 17-gallon (64 L) expansion of storage capacity without compromising accessibility.

Crafted to be adaptable, it can be used independently on benchtops or stacked on top of 30 or 45-gallon (114/170 L) Justrite safety cabinets. The Justrite 17G Piggyback’s low-height design further facilitates placement on bench tops or atop larger cabinets, with an option for wall mounting through an additional wall hanger assembly (model 25950).

Constructed with precision, this model features a robust 18-gauge (1-mm) thick steel double-wall with a 1.5 in (38 mm) insulating air space, contributing to its fire-resistant and leak-tested design. The fully welded construction maintains the unit’s squareness, ensuring longevity and providing enhanced protection in fire scenarios through minimized air gaps.

The high-performance self-closing doors, opening to a full 180 degrees, are equipped with a patented, concealed self-close mechanism that guarantees obstruction-free access to shelf space. Continuous piano hinges ensure smooth door closure, while fusible links, designed to melt under fire conditions at 165°F (74°C), trigger the automatic closing of the doors.

Safety is paramount in the design of Justrite 17G Piggyback, featuring a self-latching system with three stainless steel bullet-slams, an innovative U-Loc™ handle, and Haz-Alert™ reflective warning labels, all contributing to the safeguarding of personnel and facilities. A galvanized steel SpillSlope® shelf directs spills to a leak-tested sump, meeting EPA requirements and ANSI MH28.1 standards. Dual vents with flame arresters, adjustable self-leveling feet, and a grounding connector are further indicators of this cabinet’s comprehensive safety features.

Its durable lead-free epoxy/polyester powder-coat finish not only ensures chemical resistance but also minimizes the impact of corrosion and humidity. With over 300 safety cabinet models, ranging from 4 to 115 gallons (15 to 435 liters), Justrite caters to diverse safety, compliance, and storage requirements. All Justrite cabinets are backed by a 10-year warranty and undergo FM approval testing, ensuring adherence to OSHA, NFPA 30, NFPA 1, and IFC standards.

Considering the complexity of handling and storing chemicals, it’s crucial to select a safety cabinet that aligns with industry standards and local regulations. Justrite flammable cabinets have established themselves as best-in-class, trusted across a broad spectrum of industrial settings worldwide, including laboratories, manufacturing, oil refineries, chemical processing plants, and more.
