Window casement
Hi there!
Your operator reminds me of the 39-316 but take a look at the specifications and see if they match up with your old assembly.
I'm afraid I don't recognize the bracket, however. Can you remove it from the arm and show us photos of the front and back? Seeing how it installs on the sash would also be helpful.
Could you flip the operator over so that we can get a better look at the bracket?
Thank you! Please allow me to consult one of our senior experts on this bracket. We'll reach out as soon as we have more information.
I would suggest using some type of lubricant on your existing bracket. I believe some oil and a flat blade screwdriver should detach the bracket from the operator arm. If not, take a look at the 39-514 along with the 39-105 detach clip. This should work as a replacement if you can't get yours disconnected. Review the specifications for the mentioned parts and see what you think.
