Are all the corner castings the same?

There are eight ISO corner castings in total: top left, top right, bottom right and bottom left. The descriptions relate to the position of the castings as on the end and door faces of the container, as you look at the container from the outside. Each shipping container uses two of each of the four variations.

The most notable difference is between the top and bottom corner castings. While the bottom castings have two stadium shaped holes on two sides (plus a large stacking hole underneath), the top castings have two differently shaped holes on the side, and the stacking hole on top. The top castings have a stadium hole on the long side of the container, and a shield hole on the front or rear end of the container. It is important to note that Domino Clamps fit both the shield AND and stadium holes, but NOT the much larger stacking holes on the top of the top casting and the underside of the bottom castings.

The left and right castings, both top and bottom are just mirror images of each other but are the same in all other respects. If you are unsure which casting you are looking at, it will have been cast with two letters on the inside which will be visible when looking in through the stacking hole; TL for top left; TR for top right; BL for bottom left; and BR for bottom right.
