Gerkin double hung features a patented "candy cane" operating jamb stop which seals the ends of the interlock rail and the face of the lower sash with perfection! No other double hung has it. To compliment this patented performance, we have included three or more weather seals in every area where the sash makes a connection with the frame, including the interlock.
