Channel Balances

Home Owner from Celina, TN
I need to replace several channel balances and wanted to make sure I order the correct ones. Any help would be appreciated!
These are 25" long & are stamped 2430 and house was built in 1987

Hey there, thanks for reaching out! 

It looks like you have either the S351-25 with a 1" shoe or the S390-25 with a 1-1/8" shoe. To determine which series is needed for your window, look over the dimensions from the diagram below to confirm the depth of your bottom shoe. You'll need to select the 2430 stamp.

Comparison of the S351 and S390 balance shoes.
