An aluminum curtain wall mullion joins glazing units at a ninety-degree corner condition. An aluminum vertical fin projects outward from the corner, while an aluminum horizontal fin intersects the mullion framing at a forty-five-degree angle. The glazing units fit into the framing profiles with a one-and-five-sixteenth-inch dimension from the exterior glass face to the mullion centerline. Additional dimensional checks span six-and-one-half inches and three-and-one-half inches across the fin and frame profiles.
