Entrance Features should be installed using a combination of galvanized fasteners and urethane adhesive. First locate the center point of your door and crosshead. If your system has sidelights, take your measurement from the outside of the entire system to locate the center point. Mark the top jamb at the bottom edge so your mark is visible when installing the crosshead. Install your crosshead or combo crosshead & pediment using galvanized fasteners. We recommend using galvanized screws. Apply urethane adhesive to the back of the entry head and fasten into place making sure to line up the center mark on the crosshead with the center mark on the door jamb.
