These lift rings are designed to represent the round lift rings found on EMD diesels. They have a step etched surface to them so when folded together, they give a double sided feature that gives the illusion of the round shape of a lift ring. The rings in this package are an HO scale 3 3/8 in. O.D. by 1 3/4 in. I.D.. For those working in other scales - .039" O.D. X .020" I.D.. Here is a photo of what will be in the package.
