Welcome to SWISCO. The shape of that pulley actually has very little to do with identifying the balance. The only difference between the various Series of balance is the attachments on the top and bottom. Send photos of those, or use our channel balance guide to identify it yourself. |

The pivot bar you are showing us resembles our 26-021. I see you have an older series tilt balance. We carry the newer tilt balance which is our S795-36 with a 36B option. The balance channel is screwed at the top of the window. You will need to determine if you need a 1" wide or 1-1/4" wide bottom "T-Lock" shoe.
