Abstract: This is an improved door closer mechanism for attachment to, or incorporation into, a standard spring type door closer, or for use with a standard spring type door closer. It is particularly useful for screen or storm doors. The unique feature is a reversible pawl and ratchet assembly operating on a rod between the door and door casing, which allows the door to ratchet open freely to any desired position where it is held by the pawl until a slight closing pull or push on the door reverses action of the pawl and allows the door to close freely. While the door is closing or is fully closed, reopening of the door resets the pawl for again holding the door open as desired. Reversing of the pawl is fully automatic, and nothing has to be manually touched except the door itself.
