Custom Channel Balance Quote Request

Thanks for reaching out to us. I'm afraid we can't supply these balances with a 25-9 stamp. This is an outdated rating system that is no longer in use. The good news is that one of our normal, more modern S385-26 stamps should work fine for you. You just have to weigh your sash on a scale to verify. There's a chart on the S385-26 store page that tells you precisely how much weight each stamp supports.
