40ft Double Door High Cube units come with cargo doors on both ends. This will allow you to access from either side or both ends of the container. The additional cost of the cargo door is typically $400-$600 more then single door units, making them a more cost-efficient solution than simply modifying the container. These units have a capacity of 2694 cu. ft., and allow for more volume toward ceiling of the container as they are one foot taller. 40ft high cube cargo boxes are manufactured to meet ISO Specifications and feature security lock boxes on the cargo doors. We have these units in stock and ready to deliver.
