Thanks for writing in. Yes, the Series 775 can replace these old balances. Double-check your measurements, as this should be a 1:1 replacement. If the rods are 25" and 27" respectively, then you'll need the S775-25 and S775-27. You will need to obtain the exact weight of each window sash to know what stamp options to select, along with the 1-1/4" shoe. |
