Replacement Crank

Thanks for writing in! This window operator is similar to the 39-315 Truth Dyad Operator. Your square base is no longer available, so this is an updated style. To confirm that this is what you need, carefully double check the dimensions below.

Be sure to take a look at the related products on the website to determine if you might need replacement for the other hardware and accessories as well.
