I am writing to see what it would take to get 4 replacement channel balances to replace the Unique 25-D-40 ones I have which look like they were made June of 2003(?). I am including pictures and based on what I can see the Series 380 with the 15-005 bottom shoe is the replacement one. But not sure. The length of the channel measures 26". The length of the bottom shoe is 1" and not 1 3/32". I see the series only comes with one top shoe but no dimensions so I can only assume it will work. Does the 25-D-40 also represent the sash weight which would be 19-25 lbs? Can someone help?
Thank you,
Brian
