English to Danish Tech/Engineering Manufacturing Keys and locks

Hi,

My text says "adjustable beard" related to the manufacturing and design of keys and locks (Keso).
Even if you do not know the Danish word or equivalent for "beard" in this context, an explanation in English will probably help me as well.

Example found on the web:
All variants of Locking Systems with escutcheons/grips are available for both left-hand and right-hand application (the right-hand option swings the locking bar in clockwise direction into a groove on the right of the door; the situation is reversed for the left-hand option). In addition to Cylinder Locks with keys identical, variants are also available with *Double-Beard Locks*.
