Canyonwest Cases offers the full line of Pelican watertight Cases. Cases are available empty, filled with Pick-N-Pluck foam or with custom foam inserts made to your specifications. Pelican cases provide the ultimate protection. They meet and exceed the highest standards of industrial, military and commercial applications. Made of a lightweight, space-age ABS structural foam resin, they won't dent, crack or corrode. Cases feature an exclusive 1/4" neoprene "O" ring and multiple heavy-duty pad-lockable latches that when closed guarantee a perfect seal. Cases are watertight (to 30 feet), airtight and dust proof. An atmospheric pressure purge valve compensates for changes in temperature and altitude.
