Extended-Travel Channel Balance Quote?

Question

Channel is 26 inches and marked 25 4 DO CALDWELL. These date to about 1995.  No maker's identification that I can find.  Windows are all 36 x 60 single hung vinyl.  I need 14 of these

Thanks for writing in. This does not appear to be an Extended-Travel balance, but rather a standard type of channel balance. Specifically you have either our S380-26 or S385-26. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. For a stamp option, in either case choose 2540.
