The Vanguard USA Supreme 46F Carrying Case (Black) is a virtually indestructible, engineered hard polypropylene case that is airtight and built to withstand the most extreme conditions. The O-ring sealed case is waterproof to a depth of 16.5' (5m). It has a three-piece foam set with a recessed area inside the case for the top foam and an automatic pressure equalization valve. There are six thick, quick release, easy-open latches that lock in place, and steel-reinforced lock holders to use with padlocks for added security. The case is carried by a cushioned handle and has anti-slip rubber feet.
