ABSTRACT:
A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprises a latch arm assembly having a latch arm pivotally secured to a panel of the door and pivotable between a first, open position and a second, latched position. An activating mechanism is operably connected to the latch arm assembly by a connecting apparatus and actuates the latch arm between its first and second positions. A latch member is secured to the jamb in which the door is mounted and is arranged and constructed so that when the latch arm is moved into its second, closed position, the latch arm engages the latch member and exerts force upon the latch member in a direction substantially normal to the plane of the door so as to cause the door to contact the door frame over substantially its entire height.
