S795, open cam

Sounds like you need the S795-28 with a stamp option of 28C, and the S795-34 with stamp options of 34C and 34B, respectively. Do these balances attach to the top of the window jamb with a screw clip, rather than a hook? If so, you can simply purchase the standard balances through our online store. Since you need the 15-195B open shoe, also purchase our 15-195B for all the balances you need. The video below shows how to swap in a different T-Lock shoe; it's a very easy process.
