The 312 UltraBox is a water tight all weather mini-briefcase. With an interior that is only slightly larger than a standard letter it is deep enough to protect important documents, electronic tablets, phone, camera, etc. Accessory pluck-out foam pad layers can be added to adapt the case for sensitive electronics, gas analyzers, rf devices, etc. The o-ring seal will help to protect hand guns or special tools from rust and corrosive gasses. For OEMs a recessed frame will support an electronic instrument panel in the base.
