Hello, Unfortunately, we can't determine your sash weight based on the size of the sash. Generally, you just need to remove one of the original balances to measure then length and locate the stamp on the metal channel to choose the correct option. If there is no stamp, you'll need to weigh the sash with a common bathroom scale and follow the chart under the balance product description. Thanks for posting! |
