• bolt means mounted entirely within the housing means for movement between a latched and an unlatched position adjacent the opening in the housing;
• keeper means having a projecting strike portion which strike portion passes through the opening in the housing and engages with the bolt means to latch the closure;
• the keeper means further including a mounting portion and means for loosely securing the mounting portion to the other member, whereby the keeper is free to move in two dimensions with respect to the other member and with respect to the opening in the housing;
• keeper guide means fixed on the housing in spaced relation to the bolt and aligned with the opening through the housing;
• the keeper guide means including an inner opening aligned with the bolt and corresponding in crosssection to the strike portion of the keeper, the guide means further including beveled surface means surrounding the inner opening and diverging from the inner opening toward an outer opening larger than the inner opening, wherein the strike portion of the keeper is channeled by the keeper guide means through the inner opening into latching engagement with the bolt upon closing the closure member with respect to the frame member, whereby any misalignment between the keeper and the bolt is compensated for by the loose mounting of the keeper and the beveled guide surface means properly positions the loose keeper with respect to the bolt.
