All patio door thresholds are equipped with a weeping system. Moisture can touch the face of the sliding door and travel down into the track, where it finds its way out, thanks to two small holes (one on each side) in the threshold.

It is critical to maintaining the weep holes open in order for water and moisture to escape.
