Jam blocks

A handy person from coulmbus Ohio says:
I have windows that are two years old. I have noticed air flowing thru the window jams. They are vinyl double hung/ single hung windows. I can't seem to find these anywhere. Could you advise. Thanks

May we see some photos of the part you are describing to us?

Sorry, it is just wedged in the jamb. Maybe a jamb plug?

We carry one similar to yours, our 26-139, but it has a hole for the Series 600 balance. Yours is for a coil balance system. It isn't a critical part of the window, but nice to have. Look over and see if you can use our hole aligner.
