Can the 39-107fk replace the 39-107?

Handy Person from Grand Rapids Michigan
I have a crank on Mrvin windows from 1986, handle with the # 45012 stamped on the back side. The cover I have is like your 39-107 cover. Can I use your 39-107FK to replace this crank and cover
Thank you

Hey there, thanks so much for reaching out to us. Yes, the 39-107FK can be used in place of the 39-107. These two parts are fully interchangeable, and the added benefit of the 39-107FK is that it already comes with its own handle.
