Abstract
A door assembly includes a door frame having a horizontal header along the top thereof. A firestop extends downwardly from the header, the firestop has a plurality of sides defining a channel therein. The firestop has an at least partially open side to allow the channel to be open and receive a closer assembly. A door closer assembly is coupled to the door. The door closer assembly has a biasing assembly and an arm having a first end and a second end. The first end is rotatably coupled to the biasing assembly and is slidably coupled to the channel.
