This is the cap at the top edge of the bottom pane of an aluminum, non-tilting double hung window. THe channel balances seem to be the 385 (Caldwell?) series.

Hello,

Unfortunately, we don't carry your exact top sash guide, but the 18-109 is similar. Note that it doesn't have the same top as your part. I can't guarantee that this will work, but look over the dimensions and see what you think. Thanks for posting!
