Mortise - A rectangular cavity in a shutter stile for inserting a hinge allowing a tighter fit to the side of the window or hang strip.
A shutter mortise is a feature that is absolutely necessary to create the best fitting shutter unit. It significantly reduces the space created by the hanging hinge if mounted directly to the surface. A surface mounted hinge creates a large gap between the shutter and window jamb, or hang strip, that generally allows light to penetrate through the opening.
A mortise in the shutter style should be deep enough to accomidate both leaves of the hinge. It is then unnecessary to mortise the window jamb, or hang strip.
