The Pelican 1520 Protector Case with Foam is an unbreakable, watertight, airtight, dustproof, chemical-resistant and corrosion-proof hard case used to carry any kind of equipment that needs to be protected from the elements. It is made of Ultra-High Impact structural copolymer that makes it extremely strong and durable. The Protector Case has a 0.25 inch (6.4mm) neoprene o-ring, and easy-open double throw latches that seal perfectly, and includes an automatic pressure equalization valve for quick equalization after changes in atmospheric pressure. It is carried by an oversized handle that enables a person to use two hands for heavy loads.
