The 0450 has 2” polyurethane wheels for optimum load distribution over soft terrain. By locating them on the back of the chest, they offer a wide, stable track. This also leaves the front of the chest clear of wheel obstructions, creating more usable drawer space.
The 0450 has two built-in Automatic Pressure Equalization Valves: one for the top lid and the second for the main compartment. They make opening the case easier after altitude changes by balancing the interior pressure with the ambient pressure.
