Roger, will wait for pic. When you and I are talking about "channel" we do not mean "frame" as is shown in Manual Sec. 3, fig. 48. The frame is the whole metal piece for both stationary and sliding window. Window "channel" is typically felt covered corrugated metal that fits into the frame and into which the glass fits. "Channel" is supplied in a long piece which you may have to trim to length before installing. this stuff is also used in the windup door window "frame". yes?

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
