Hi,
I have a non tilt window balance I am trying to replace, I have narrowed it down to a Series 380 or 385, top shoe should be a match to 19-005, lower shoe most likely is a 15-004 but it is not a visual match. Rather than being a full 1 inch in depth, mine is 15/16, with a different profile. Any insight is appreciated. Length of channel only is 29 inches, window weight is less than 10 pounds.
Thank you,
Garth
