Hello,

It looks like both of your operators have been discontinued and are not longer being sold. We do have some possible solutions but we can't guarantee that they will work and if they do, you may need to make some modifications to get them to install properly. 

Take a look at our 39-389 or 39-390 operators depending on the size that you need for your awning window. As for your casement window, see our 39-094 and 39-095 operators. Thank you and let us know if you have any other questions!
