Older 39-025 with half moon cutout

Hello,

I know the original operator used by Silverline had a cut gear but I have replaced it with the 39-025 without any problem in the past. We also offer operators used on the Crossly windows, the 39-251 and the 39-252. These have a short link arm that has a threaded hole at the end which takes the shoulder screw 33-067. It also has that cut gear that you say you need. Take note that you might need to drill out the hole in the window linkage to use the shoulder screw. Look over the specifications of these parts and if you're still not sure if one of these could work, feel free to get back to us with detailed photos of your original operator uninstalled, along with written-out dimensions compared to ours. Thank you.
