See our S395-12. This looks like it matches what you have. You also have to choose a stamp option that reflects the strength of the balance. Your stamp 1190 is from a rating system no longer in use. To know what stamp to select, weigh your window sash. Match that exact weight with one of the weight ranges listed alongside each stamp option under the product description on the balance's shop page. |
