Three panel doors secured by one standard padlock. The unique design ensures high capacity to weight ratio and maximum internal to external volume. The cage has multiple shelf positions, and the shelves are removable. Ideal for transforming a 20ft container into a mobile warehouse with full access through the center aisle in transport or storage. Six cages fill one 20ft container, leaving the center aisle open, while nine cages fill the container completely. Includes blocking and bracing.
