Replace 2 pieces

Hello, thank you for posting,

With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. 

You will need a 28" balance length. 

The 32 at the end of your stamp should indicate that the window sash weighs 32 pounds. Please obtain the weight of the sash to check this. If so, you can use a 2760 stamp option that can support a 30 to 33 lb window sash. Please review and let me know if you have any additional questions!
