These D rings are very nice. The opening is 5/8" , overall measurement is 7/8" x 5/8". The metal itself is 3 mm thick. These rings are not welded, but have a nice tight closure. But if you do need to open them you can do so with a pair of pliers (wrap the pliers in masking tape to avoid scratching the finish). Nickel finish.
