Window balances
Hello! Your balance appears to be a match for our S795-26. I believe this is the part you want, but look it over and see if you agree. Note that the metal channel is 26" long and the "T" lock shoe is 1-1/4" wide. You should check both of those details on your own balance before you buy anything.
I've never seen a shoe that wide for this configuration, unfortunately. The only sizes are 1" and 1-1/4". make sure to remove your shoe from the window before you measure it; it's not possible to get an accurate dimension otherwise.
The 1" wide shoe that's compatible with this style balance is our 15-194. This is only sold separately.
These just pop on and off. We actually have a video on the 15-194 store page that shows how this is done. I'll share that below in case you haven't already seen it.
