Thanks, Paul. We took the rail and sweep apart. Pictures attached. There appears to be a leak at the bottom of the door hinge area, probably because the sweep (no longer) extends far enough. The sweep is 1" wide and doesn't quite extend the full 21-3/8" of the drip rail which when screwed to the lower door frame holds the sweep in place simply by compression. In investigating possible suppliers, it might have been Style-rite, Clifton, NJ (probably no longer in business) or Keller Glass out of Texas which shows the (unusual) 1" sweep. Anyway, my contractor and I would be interested if you came up with anything else. At the moment, we think a new and slightly longer sweep would be all we need. By the way, can you tell us where you are located?
