What is the maximum width limitation for gooseneck tunnel inserts?

The maximum width limitation for gooseneck tunnel inserts is indeed set as "no limit." This allows for flexibility in the design and manufacturing of containers, especially considering different types of cargo and loading requirements. Gooseneck tunnels are specifically designed to accommodate the structural needs of trailers while maximizing the usable space within the container.

When there are no width limits imposed, it enables manufacturers to optimize the tunnel design for better functionality, ensuring that various cargo dimensions can be handled without restriction. This situation contrasts with the other options, which suggest specific maximum widths; such limitations could potentially restrict the design capabilities and usability of the gooseneck tunnel inserts. Thus, the absence of a maximum width encourages innovation and adaptability in container design.
