Protective device for shipping container corner castings

Abstract

A protective device for installation on a corner casting of a shipping container, the corner casting having a lower wall and an aperture. The protective device includes (a) a base, with an upper surface configured for engagement with the lower wall and a lower surface configured for engagement with a ground surface to provide a barrier between the corner casting and the ground surface, (b) an inner component sized and configured for insertion through the aperture, and (c) connection means for connecting the base to the lower wall of the corner casting. The connection means preferably comprise the inner component being rotatable between first and second configurations; in a first configuration, the inner component is rotated into an aligned orientation aligned with the aperture to allow insertion of the inner component into the corner casting interior; in a second configuration, the inner component is rotated into a misaligned orientation disallowing passage of the inner component back out through the aperture, such that the inner component engages the lower wall from within the corner casting while the base is retained against the outside of the lower wall to provide the barrier.
