Passageway metal plaque with lock missing - need dimensions


Alexandre Uster von Baar
 

The metal piece that goes over the passageway door, where you can add 2 locks, is missing. I would like to have another one made (unless I can find 1 for sale).
Could anyone please send me the dimensions of their?
Thanks in advance, sincerely, Alexandre
