Hello,

Take a look and compare the dimensions of the Caradco and EntryGard operators that we've related for you to your assembly, paying close attention to the length of the shorter link arm. Please note that both of these operator pairs are compatible with the 39-107FK folding handle and cover kit. Let us know if you have any other questions and thanks for posting!
