    Abstract: A flashing end dam having an angularly adjustable leg (adjustable end dam) includes a bottom leg, and adjustable rear leg, a side leg and a moveable web. The adjustable end dam is bent from a blank such that the bottom leg and the adjustable rear leg are formed, while bending a portion of the bottom leg and the adjustable rear leg to form the side leg and the moveable web. The adjustable end dam may be installed above a window opening in a masonry wall. The adjustable end dam is normally placed in a corner above and past the window opening. However, the adjustable end dam may be installed in any suitable application. If a nonparallel cavity variation exists between the structural wall and the exterior facing, the adjustable rear leg of the adjustable end dam may be bent back or forward to span the cavity.
