Thanks for posting. See our S377-12. You will need to choose a stamp option. Look for a stamp code on your metal channel that conforms to one of the stamp options on the product page. You could also weigh your window sash, and match that precise weight with one of the weight ranges listed with each stamp option listed on the product page. Many thanks.
