When the bottom of the sweep fills in the door gap, drill pilot holes through the sides and screw it down. Measure the distance between the door frames at the floor. Transfer this measurement to the threshold, put on a pair of safety glasses, and cut it to this length with a hacksaw or jigsaw.
Place the threshold onto the floor between the frame members and drill pilot holes for the mounting screws. Mounting holes in the threshold will have been pre-drilled at the factory to facilitate this action. Turn in the mounting screws and tighten them securely.
