设计to mount on top of our standard 30- and 45-gallon (114- and 170-L) safety cabinets, these Piggyback cabinets create a safe storage space without taking up any valuable floor space. Cabinets can also be used independently as a wall-mount unit or on a countertop. ChemCor® thermoplastic coating on all interior surfaces provides superior protection against corrosion from drips and off-gassing from harsh chemicals. Seam-free surface eliminates the need for rivets or fasteners which risk corrosion from seep-through chemicals. Non-porous surface resists staining and cleans up easily. ChemCor® Lined Hazardous Material Safety Cabinets have the same quality features found in Justrite's flammable cabinets — including double-wall, 18-gauge (1mm) welded steel construction, 2" (51mm) liquid-tight containment sump, dual vents, adjustable shelves, three-point stainless steel bullet self-latching doors with U•Loc™ padlockable handle and Haz-Alert™ reflective warning labels. An all epoxy baked-on powder-coat finish, inside and out, provides increased chemical resistance. Interior ChemCor® liner ensures complete corrosion resistance and protection. Self-close door(s) shuts and latches automatically when a fusible link melts at 165°F (74ºC) under fire conditions. Unique, concealed self-closing mechanism offers obstruction-free access to contents.
