I believe this an older version of our S770-32 Channel Balance. Look it over to confirm. You'll have to choose a stamp option as well. Your old balance's stamp is from a rating system we do not use. To know what stamp to select, weigh your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp on the S770-32 shop page. |
