Custom Hinge Selection Tool
Bend - Swage - Offset : Leaf Offset
Offsetting a leaf is the opposite of swaging.
With offsetting, the leaf material of one or both leaves is pushed in the direction away or opposite of the pin side of the hinge.
Offsetting requires a dimension either from the center of the pin to the surface of the leaf or the distance between the 2 leaves when closed and parallel.
One reason for offsetting is to move the barrel away from the mounting surface so paint is not damaged when operating the hinge.
