Need help

Many thanks for posting. This looks like our S795-24. For a window sash that weighs 25.6 lbs. sash, you will need to choose a stamp option of 24E. Before proceeding, confirm this balance attaches to the top of the window jamb with a screw clip. If it uses a hook like our 15-198 instead, please let us know--this is not a stock item, but we can provide it for you via custom order. We'd just need to know how many balances you need. If it uses the screw clip though, you should be good to go. Let us know if you have further questions.
