Made of injection-molded ultra-high-strength polypropylene copolymer resin, this SKB Cases 3i-Series 2922-16 Wheeled Waterproof Utility Case is built to withstand the most extreme and demanding shipping and handling conditions on the planet. The large 29 x 22 x 16" interior is completely empty, so you can customize it to your needs using an optional interior foam and dividers set or your own creativity and materials. Three snap lock handles provide carrying options, or you can extend the telescoping handle and tow the case behind you if it's too heavy to carry.
Design features include gasket sealing that makes the case dust and waterproof, a molded-in hinge for added strength, five stainless steel reinforced padlock holes, and seven trigger release latches arrayed in pairs on two sides and a set of three on the front that seal the interior tight. The case is further resistant to a variety of hazards that you may encounter such as impacts, ultraviolet (UV) radiation, solvents, corrosion, and even fungi. A pressure relief valve comes into play especially during air transport by regulating the internal pressure, keeping your gear and the case from getting crushed and allowing you to open the case without having to break a tough pressurized seal that may develop.
