Window channels

Thanks for reaching out! Your balances appear very similar in style to our Series 795 Channel Balance. The attached at the bottom of the assembly looks to be some variation of our T-Lock balance shoes. You can likely use the 15-195 which comes assembled on the balances but it might be good to find an undamaged shoe, if possible, to confirm that your shoe does have an open cam.

Unfortunately, I cannot cross-reference your balance stamp with the stamps from our balances, so I'll need to know the exact weight of your sash to confirm the option you need. 

I'll also need to see the installation hole at the top of the window track where the balance installs, it is important to see the shape of it to determine exactly how it connects to that installation hole.

Please let me know if you have any questions in the meantime.
