Channel Balance assembly

Question

Hi, I have determined that I need the 795 series Channel Balance assembly but I am a little confused on the size. My current rails are stamped "32-7 BSIN RL" and one is "26 7 BSI RL". I am assuming that the 32 and 26 are the sizes although the 32 measures a little over 33 and the 26 a little over 27. I also assume the weight is "B". Is this correct?
Thank you,
Wendell

Hey, Wendell. Your stamps are a little different from the typical Series 795 balance. The stamps typically only represent the spring strength rating, they shouldn't be used to identify other details. I recommend just measuring the length of the metal channel and going by that. To identify the right Series 795 option to work for you, you will need to weigh your sashes.
