This black iSeries Waterproof Utility Case from SKB features an empty interior, allowing you to customize the space according to your needs. This impact-resistant case is made from injection-molded polypropylene copolymer resin to be resistant to UV radiation, solvents, corrosion, and fungi according to MIL-STD-810F standards. It is IP67-rated and gasket-sealed to make it dustproof and temporarily submersible. Molded-in hinges, patented trigger release latches, and padlock holes with stainless steel protector clips add to the security of the case. Three rubber overmolded cushion grip handles snap into vertical/horizontal position for convenient carrying options, and in-line skate-style wheels on the side allow it to be pulled along the ground when the case is packed. A built-in automatic ambient pressure equalization valve (MIL-STD-648C) allows for safe air travel.Polypropylene-Copolymer ResinDust and WaterproofCorrosion, Fungus, and Impact ResistantPatented Trigger Release Latch SystemOvermolded Snap-Down HandlesIn-Line Skate-Style WheelsMade in the USALarge heavy-duty handles and wide-set double wheelsUltra-high-strength polypropylene copolymer resinUV, solvent, corrosion, and fungus resistant (MIL-STD-810F)Complete gasket seal makes these cases absolutely watertight (MIL-STD-C-4150J)Automatic ambient pressure equalization value (MIL-STD-648C & IP67)Resistant to corrosion and impact damageMolded-in hingesStainless steel lock hasps
