A door stop assembly for vertical insertion in a single hole in a floor in the path of a swinging door includes a tubular housing with a top flanged housing for retaining the assembly in the floor, a tubular door check rod within the flanged housing and spring biased to extend up into the path of the door upon being triggered, and a trigger bar coaxially extending through the door check rod. The top surface of the trigger bar is normally flush with the flange so that the door check cannot be accidentally extended by merely stepping on it. When depressed below the flange surface, a steel ball, normally contained within two aligned radial holes in walls of the door check bar and housing, drops into an annular groove in the trigger bar to thus release the door check bar from its housing. When the door check bar is pushed down, the groove in the trigger bar replaces the ball in the aligned holes to relock the check bar in its housing.
