Help identifying parts

A handy person from Summerville, SC says:
26-7 I have attached multiple photos. I believe I have a t-lock balance system. What length do I need. The part is marked 26 but measures 27".

I think you have an older model of our S795-27, one that uses an older and outdated rating system. I recommend weighing your sash on a scale to confirm which S795-27 stamp option will work best for you.

I also recommend purchasing our 15-195B open cam shoe separately, since this appears to match your original. You can swap it out once you get them, it's very easy. The video below shows you how.
