Thanks for posting. This looks like either a S380-26 or S385-26. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You'll have to choose a stamp option. Your stamp code of 25-E-50 I believe might translate to our stamp option of 2560, which is for a window sash in the weight range of 28 through 30 lbs. But to be certain, I'd get the exact weight of your window sash to confirm this. |
