Abstract: A mounting plate enables the bracket of a conventional door closer to be removably retained to a door casing or the like. The mounting plate has a pair of tabs that define slots for slidingly receiving the flanges of the closer bracket. A stop permits entry of the closer bracket into the mounting plate slots from only one direction and also limits sliding in that direction. Bumps on the mounting plate cooperate with the closer bracket mounting holes to loosely restrain the closer bracket from sliding out of the mounting plate in the other direction. After the mounting plate is secured to the door casing or the like, the closer bracket is slid into the mounting plate slots, and the closer bracket functions in a completely normal manner. When the closer bracket must be removed to provide full utilization of the door opening, it is necessary only to slide the closer bracket out of the mounting plate.
