PGT Channel Balance and Top Sash Replacement I.D

Thanks for posting. See our S395-24 Channel Balances. Your stamp option of 2320 corresponds to a window sash weight range of 9 through 15 lbs.

In regards to your Top Sash Guide, I can't be as certain as your old piece appears damaged, but the 18-166 seems like a good place to start. Carefully compare the dimensions listed on the product page and see if you think it's a possible match. 

Does the Top Sash Guide on the other side of the window also have this 'cut out' design? Could we see a picture of it? In any event I am not certain this would matter in terms of function, but I will see if one of my colleagues can confirm this.
