hello,
I'm trying to replace these broken window sash. These have 193 FS CALDWELL and seems to measure about 20 inches long. I also need matching top guide to go with these as the current ones got brittle and snapped.

Hey there. Start by comparing your channel balance to the S380-20 or S385-20. The only difference between these two balances is the shoe depth. See below. For a stamp option choose 1930.

Thanks for the reply. Mine measures closer to 1inch so i'll go with the S380-20. Which top guide will fit these ?

These can work with a number of different Top Sash Guides. If you're unsure what you need, send us photos of your old one, removed from the sash and from a front and side angle, and we should be able to narrow it down.

Hello, thanks for your help! I took some photos of the current top sash guide. Could you give me some recommandations?

Thanks. We don't have an exact match for this Top Sash Guide, but the 18-008H might work as a substitute. Review the dimensions and see if it matches up.
