ThePoseidon 10 235x181x105 mm is a waterproof small arms carrying trunk made of durable 6 mm thick polypropylene and modular foam that allows us to customize the space to our needs. The trunk has a compensating valve, IP55 certification and military NSN designation. Durable plastic Poseidon cases are made by injection molding from 6 mm thick polypropylene. PP is a highly flexible thermoplastic material that is resistant to bending, falling and breaking. Polypropylene is also characterized by low weight, non-flammability, low water vapor permeability and high resistance to acids, alkalis, organic solvents. 100% water resistance Thanks to the double-sided seal, Poseidon trunks are airtight and 100% waterproof, so the contents of the crate are safe even after full immersion in water, heavy rainfall, etc. The crate additionally uses an equalization valve, which automatically regulates the pressure inside the crate and prevents water and dust from getting inside. Cases with an equalization valve can be safely transported underwater and in the air. The chest meets military standards, as evidenced by the NSN stock designation given to products for the military (NSN: 8145-23-114-7579). Robust closure The Poseidon 10 trunk is closed with 2 solid buckles, and thanks to the use of hooks we also have the possibility to secure the chest with a standard padlock. The solidity of the construction is guaranteed by steel pins in the hinges and a double-layered folding handle. Modular foam Unlike ordinary "shark's jaw" foam cases, Poseidon trunks use a modular foam insert, which allows us to organize the transportation space to suit our needs. The foam inserts in the form of cubes can be easily removed, so that the transport space can be precisely tailored to a particular unit of weapon, camera or delicate electronics.
