I need to replace several window channel balances (please see pictures). They are 26 in. long and 1/2 in. wide. They are marked "25 4 KN Caldwell" and are approximately 22 years old. I don't know the weight of the window these are supporting, but it is vinyl framed and 44in wide x 28in tall. If you need further pictures or info, please let me know. I tried to use the parts identifier portion of the website, but can't tell the type of lower attachment this has.
Thanks,
D
