ODD Size Designator
Odd size designators are an alpha numeric descrip- tion. The first two digits specify the height whole num- ber with an alpha designator specifying the height fraction. The second two digits specify the width whole number with an alpha designator specifying the width fraction. And the last alpha designator specifies the depth. If he height or width is less than 10 inches, use a 0 in front of the dimension.
