revolves around the pin.
Width The dimension from the center of the pin

Diameter (OD) of the knuckle is approximately
two times the material thickness plus the pin diameter.
Clearance The dimension between the outer face
of the knuckle and the opposing edge of the leaf cutout over the entire
range of rotation. Paint clearance is a dimension and not a feature you
add to a hinge. If you need a hinge that will be painted, you may need
to ask for more paint clearance than is provided on our standard products.
You should specify the minimum paint clearance you require.
