Abstract
The subject invention is a delay door closer that is to be used in conjunction with a dual door arrangement such as a screen door mounted in conjunction with an entry door of a house or other building. A catch mechanism is mounted on the door jamb with the catch mechanism functioning to lock and hold the screen door in an open position when the entry door is in the closed position. Upon opening of the entry door a sufficient amount to where the user is now able to enter the building, the catch mechanism is disengaged which will cause the screen door to be moved from its open position to a closed position.
