Casement window sliding hardware

Hi there!

Thanks for reaching out to us. Take a look at the 39-014 and 39-013 operators. These looks like modern versions of your assembly. Note that they have a nylon roller at the end of the arm, so you'll want to make sure your old one does too. Review the specifications and see how they compare with your old assembly.
