I have a few broken window channel balances. The windows are all non-tilt windows with 1/2? channels. I tried to match it to your channel balances and it appears to match your S380 series (with a 19-005 channel balance top and 15-005 balance shoe) Can you confirm based on the attached pictures?
The manufacturer of the window appears to be Kinco, Ltd out of Jacksonville, FL. (Series Mark 40/50 HP; H-LC 30-53x96)
After I removed the channel balances from one window I determined that not the channel balance but a broken sash guide appears to be the issue. Unfortunately, I am not entirely sure which replacement sash guide to get. Can you assist? It appears to be a 18-009 (or maybe 18-018) sash guide?
Any help would be greatly appreciated! Thank you!
