The Giant Lock Box is constructed from all steel components. The walls and doors are 16 gauge steel. The doors have four welded hinges each, opening 270 degrees to be out of the way. When closed they securely lock with heavy steel bars clasping from the top and the bottom of the container. Each door has gaskets fully around the door to stop insects and rodents from getting into the container. The Giant Lock Box is 16' x 8' x 8' high. Each container has  vents installed to allow for water vapor to escape the container  and prevent condensation.
