Thanks for posting! The part in your first picture appears to be a screw plug like our 26-036. This goes in the hole in the master window frame. The 19-036, on the other hand, is a mounting screw way that you'll find at the top of your balance.
Speaking of your balance, I'm actually not sure what yours is. If you were to show me the bottom end, as well as whatever clip or shoe is found there, I could identify it for you. |
