Thank you for posting on our discussion board. I believe either our S380-18 or S385-18 balance will work for you, depending on the 'depth' measurement of the bottom balance shoe. You will need to measure the depth of your bottom shoe, the way it is shown in the diagram below, to decide which of the two balances is a match. Whichever one chosen will use a 1740 option that supports a sash weight of 14-17 pounds. Alternate view of 15-004

Then most likely you need the S385-18. When it comes down between these two types of balances, if the shoe is at all greater than 1" deep, its safe to assume its the Series 385, even if the depth just wore down a bit from age and use. Let me know if you have any other questions. |
