1/2 inch channel balances, non-sliding window
Hello, thanks for posting! It looks like you will need our S395-27 with the 2630 stamp option. If you have any further questions please don't hesitate to ask!
We don't recommend straying from the stamp option on your original hardware. Choosing a spring that's too strong can make the window difficult to open, whereas one that's too light won't keep the window up.
I apologize for this inconvenience. The balances that you are inquiring about have been ordered but, due to the state of affairs, things have been moving a bit slower than we'd normally expect and our information is limited. You can sign up for our auto-notification service on the product page and you will receive an e-mail notification as soon as we have the part back in stock.
