This pivot shoe looks like our 15-228. If the Coil Balances are 1/2" thick, then you need the Series 160 Coil Balances. Look for stamps on the coils that indicate what spring weight you need. If there are no stamps or you are unsure, you'll need to obtain the exact weight of that window sash. Give us that exact weight and we can work out what you need. |
