The self-adhered weather resistant barrier sill corner is cut to fit the rough opening and applied to the sill and jamb over the sill liner. The square flashing piece features indicated cut and fold lines with four-inch minimum dimensions to form a folded corner piece. This flashing component integrates into the exterior wall assembly to protect the window opening from water infiltration at the sill-jamb intersection.
