The corner intersection of a curtain wall system establishes the dimension point at the mullion centerline relative to the face of glass and edge of slab. An exterior vertical fin, designated FP-1, is anchored to the mullion profile with a projection ranging from three and three-eighths inches minimum to one foot maximum. Glazing pockets accommodate quarter-inch typical glazing infill with precise dimensional layout offsets for framing alignment. Reference sheets A364 through A373 provide additional fin connection and engineering information.
