ABSTRACT:
A method of manufacture of a radius drip cap for sealing arcuate window frames when installed on an architectural window assembly previously installed on a building wall comprising uncoiling a strip of aluminum, cutting the strip into aluminum pieces, pressing each strip forming the strip with three stepped flanges including a pair of vertically extending upper and lower cap flanges separated by a horizontally extending cap flange linking the pair of vertically extending flanges together, slitting an uppermost of the vertical cap flanges at transverse intervals forming longitudinally spaced upwardly opening slits, and applying a closure to each of the slits on the upper cap flange to render the slits watertight on the uppermost vertical cap flange for precluding water leakage through the slits.
