This looks like an S770-24 with a rivet in the top hole so that it uses an S-Clip to attach to the window jamb. We can custom make this for you, but we need you to give us the exact weight of the window sash so we know what stamp option to give your balances. |

I just sent you an email to order (12) of these Series 770 24" balances, stamped 24C, and with a rivet in the top hole. You can reuse your old s-clips if they're undamaged, otherwise see our 19-029. Let me know if you have any further questions. |
