Storm Door Lever
Hey there,
Thanks for reaching out! The best replacement option we have for the handle set you have here is the 40-212 Larson Classic-Elegance Security Storm Door Handle Set. Unfortunately, I cannot guarantee that it would work as a suitable replacement and I am not too confident. There is a strong likelihood that the handle set will not be compatible with your existing mortise lock.
I'm sorry to say that we do not carry anything that would work in place of the mortise lock you have here.
Take a look and see what you think!
I'm happy to help! Please don't hesitate to reach out with any other hardware repair projects you might have.
Have a great weekend!
