Question

This is my second submission. This is a different window that also needs new balances. Same house. Western Product window that's 23 years old.

Hello there. This looks like an S350-28 Channel Balance. You have to choose a stamp option also, which reflects the balance's strength. Your old balance's stamp of 27-9 is from an outmoded rating system. To know what stamp to pick, weigh the window sash. You can use that exact weight to pick the right stamp option.,
