What is the minimum distance from a rail insert/section to a corner fitting on an end rail?

The minimum distance from a rail insert or section to a corner fitting on an end rail is specified to ensure structural integrity and functionality in handling situations. The correct answer is based on design and safety standards established within the industry to prevent issues that could arise from improper clearance.

A distance of 150mm allows for adequate space to accommodate necessary movement and load distribution during transportation and handling. It helps to avoid any potential wear or damage to the corner fittings that could occur if the distance is too short. This measurement also ensures that the fittings can function properly without interference from the rail insert, maintaining the overall safety and reliability of the dry van structure.

While the other distances listed may seem reasonable, they do not align with the established industry standard, which emphasizes the importance of maintaining appropriate clearances to enhance the durability of the container and prevent structural failures.
