I think I need two (2) Series 795 channel balances ? 34" long and "B" stamp option as my sash weighs approximately 21 lbs. However, I need clip on top rather than screw on. I have attached pictures that show what I presently have. I think it looks like the 1-1/4 T-lock, closed cam. Can you please confirm. Let me know the the price and how to order. Thanks.
