Crank replacement

Hello,

We'd be happy to help but it's tough to make out the details of the operator arms that connect to the sash with the screen in place. If you could either remove the screen or the entire operator assembly to show us, that will help us narrow down your options. Thank you! 

Thanks for getting back to us. Your operator resembles the EntryGard 39-031 and 39-032. The determining factor would be how the length of the shorter link arm compares to your assembly. Take a look and let us know if you need anything else.
