Window balance 25 4 EW CMC 10

Hi there! It looks like you have an S350-26 with a stamp option of 2540. As for your sash guide, I'd need to see pictures of it undamaged and out of the window in order to confirm a match.

My sincerest apologies! In that case, you'll need either the S380-26 or S385-26. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need the stamp option of 2540. Please let us know if you have any questions!

This looks like our 18-171 Top Sash Guide. Give it a look and see if you agree. As far as sash stops go, it depends on what you originally had. If you want to send us pictures of your original we'll see what we can do.
