The Justrite 29937 SpillSlope replacement shelf is a galvanized steel shelf that can be used with 30-, 40-, and 50-gallon Justrite safety cabinets and 17-gallon Justrite Piggyback cabinets (each sold separately) to store safety cans containing flammable or hazardous liquids. The shelf can support up to 350 pounds and slopes slightly to direct spills to the back of the cabinet. It is made of galvanized steel, which is resistant to rust, dents, and certain chemicals. The shelf measures 1 x 39-3/8 x 14 inches (H x W x D) and has a shipping weight of 10 pounds. (H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.)

Hazardous storage cabinets are used to store, organize, and segregate safety cans containing flammable or hazardous liquids. Some cabinets are made of galvanized steel and are double-walled to reduce the risk of fires. Others are made of polyethylene, which is resistant to certain acids and corrosive liquids. Cabinets may have standard hinged doors that close manually or self-closing hinged or sliding doors that close automatically. They can be color-coded: yellow for flammables; red for combustibles; blue for corrosives; green for pesticides; silver or light neutral for laboratory materials; and white or gray for other waste or outdoor lockers. Certain cabinets are FM Approved and meet National Fire Protection Association (NFPA) and Occupational Safety and Health Administration (OSHA) standards for the storage and handling of flammable liquids. Hazardous storage cabinets are used in a variety of commercial and industrial environments and can also be suitable for home use.

Justrite manufactures safety equipment to store, transfer, use, and dispose of hazardous materials. The company, founded in 1906, is headquartered in Des Plaines, IL.
