Abstract
A door closer is provided to automatically pull a storm or screen door to a fully closed position without user action. The door closer includes a bracket housing with a cam switch movable along a track as the door opens and closes. The closer cylinder rod is engaged with the cam switch until the door is fully opened. The cam switch biases the closer cylinder and rod as the door approaches the closed position.
