I had a local shop (now closed since the owners retired) hang some door slabs for me and they included a weatherstrip with each door that looks like this:
They left them off presumably because the doors were unfinished, but now that they're finished and installed I'd like to seal up the bottom of the doors.
What's the preferred way of installing these? Adhesive? Screws? Staples? And if I do use fasteners, where should they be? Note that the little flaps appear to be too close together to fit up the sides of an exterior door.
Or should I purchase a different kind of weatherstrip from somewhere else? The thresholds on the door frames are adjustable in height so I have some wiggle room.
