Greetings! I believe you have an older style "Bilt Best" window operator. Take a look at the 39-027E & 39-028E 9-1/2" Operators, or the 39-013 & 39-014 13-1/2" Operators. I am not sure of the arm length of your operator, so compare these products with your old parts and see what matches closest. You will also need to replace the track and handle. Take a look at the parts I've associated on this page. Please note that you might need to retro fit your wood sill cover to accommodate the newer style operator. |
