The Justrite Sure-Grip? EX Piggyback Safety Cabinet with Self Close Doors is designed for the storage and segregation of flammable liquids in lab, construction, or engineering settings. With exterior dimensions of 18 in H x 43 in W x 18 in D (457 mm H x 1092 mm W x 457 mm D, its low-height design allows you to expand available storage by 12 gal (45 L) without taking up valuable floor space. Use independently on bench tops or stack on top of 30- or 45-gal (114- or 170-L) Justrite safety cabinets. It can also be mounted on a wall with an optional wall hanger assembly (model 25950). This yellow model is constructed with a sturdy 18-gauge (1-mm) thick steel double-wall, with 1.5 in (38 mm) of insulating air space for fire resistance. The fully welded, not riveted, construction holds the squareness of the unit for a longer life and offers greater protection in a fire since air gaps are reduced. High-performance, self-closing doors open to 140 degrees. A patented, concealed self-close mechanism provides obstruction-free access to shelf space. The doors self-index to guarantee they will close in tight sequence. Continuous piano hinges ensure the doors close smoothly every time. When used properly as designed, safety cabinets with self-closing doors shut automatically in case of a fire. The self-closing doors, under tension, are held open by using fusible links. Under fire conditions, when the ambient temperature reaches 165 F (74 C), the links melt and the safety cabinet's self-closing doors automatically swing shut. The self-latching system engages with three stainless steel bullet-slams located at the top, bottom, and center locations of the door. For replacement fusible links, order model 29988. For added security, each cabinet comes with an innovative U-Loc? handle that does not require manual rotation to engage the mandatory latch. Cabinets include a cylinder lock and key set, or you can choose to use your own padlock. Haz-Alert? reflective warning labels that read "FLAMMABLE - KEEP FIRE AWAY" are highly visible under fire conditions or during power outages when illuminated with a flashlight. The cabinet also features dual vents with flame arresters, four adjustable self-leveling feet, and a built-in grounding connector. Its durable lead-free epoxy / polyester powder-coat finish provides excellent chemical resistance inside and out, as well as minimizes the effects of corrosion and humidity. Justrite supplies more than 300 safety cabinet models ranging from 4- to 115-gal (15- to 435-L), to meet a versatile range of safety, compliance, and storage requirements. All Justrite cabinets carry a 10-year warranty. This model is tested and approved by FM Approvals. It complies with OSHA, NFPA 30, NFPA 1, and IFC requirements.
