Hello there. Good eye, this does look an S395-37 to me. The only issue is choosing a stamp option. Your stamp code of 36-9 is from an older rating system we no longer use. To know what stamp option to select, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the product page. Let me know if you have any other questions. |
