Stamp option?

Hi there, thanks for the inquiry. May we see your balance removed from the window? We'll need to see the top and bottom nylon fittings to determine the series you need.

Just to add on: if your question is just about what stamp option you need, the stamp code of 28-1 should correspond to our stamp option 2810, which is for a window sash in the weight range of 7 through 12 lbs. Let us know if you need anything else. Or like Kathleen said, if you want to confirm the balance's identity, show us photos of the top and bottom nylon fittings.
