Thanks for your help. I have 2 sets of window balancers, my original BSI 25-3 and an attempt at replacements marked 25-3 GP5 CMC 7. My original BSI parts started screaching when lowering the window and, upon inspection, had a frayed cable so we had our contracter find us replacements.
Although the CMC parts matched the physical characteristics of the BSI's, they don't hold the window up all the way. The window is 17.5 pounds. The springs are very different in length and tension apparently.Anyway, your site shows what appear to be form-factor replacements with specified weight ranges. At 17.5 pounds, would you suggest the 15-19 range or the 19-25 range?
I ask because my two samples of balancers, my original that worked great, and the replacements that don't work so great, are both marked 25-3. Any suggestions would be appreciated.Thanks again, Alan
