A door latching device comprising (a) a housing, (b) an engaging element, (c) a movable latch pivotally mounted with said housing about a pivot location, and (d) means for limiting latch motion over a range, the means being adjustable to multiple different positions over the range such that the amount of permissible latch movement is variable to be a selected amount in the range, such that there is a different amount of travel possible by the latch between a first position of non-engagement and a position of engagement with the engaging element, the first position of non-engagement being different for different positions of the limiting means and wherein the means for limiting the latch in the removed position engages the latch to normally remain retracted from the engaging element under the principle of unstable equilibrium wherein the center of gravity of the latch in an unlatched position is located in a position relatively closely vertically aligned with the pivot location.
