ABSTRACT:
A sliding door unit having a stationary and a movable door panel has an improved sill which underlies and supports the door panels. The sill includes sill surfaces of different elevations for imposing a gravitational potential on any water seeking to infiltrate between the door panels. In addition, the sill includes a drain tank which operatively communicates with the highest sill surface for draining any water reaching that sill surface to an exterior side of the sill. The sill also includes an improved support member for supporting an outwardly extending threshold of the sill. Furthermore, the sill includes a guide system for guiding the stationary door panel into place during manufacture of the door unit.
