LATCH MECHANISM WITH ENGAGEMENT INDICIA
A door latch slide for engagement with a strike plate in a doorjamb. The door latch slide comprises a latch slide body engageable with an actuator device mounted on the door for moving the latch slide toward and away from the strike plate, the latch slide body being adjustable with respect to the door to adjust extension distance toward the strike plate. A latchbolt extends from the latch slide body and has a non-flat sweep side for contacting an outside of the strike plate to cause retraction of the latchbolt away from the strike plate as the door is closing and an opposite flat face for contacting an inside of an opening in a face of the strike plate to prevent the door from opening when the latchbolt is extended toward and into the strike plate opening. The latchbolt has a pair of indicia on at least one side thereof, one of the indicia indicating a minimum desired distance for extension of the latchbolt into the strike plate opening and the other of the indicia indicating a maximum desired distance for extension. The latch slide may be adjusted during installation of the actuator device by visually extending the latchbolt into the strike plate opening, moving the latch slide body toward or away from the strike plate until the strike plate face is between the pair of indicia on the latchbolt, and setting the latch slide body with respect to the actuator device so that the latchbolt when extended maintains the strike plate face between the pair of indicia on the latchbolt.
