Do I have the 39-109B pella window crank

Question

the depth of my extending part that the crank will screw on to is 3/4 long but the description says they are 3/8 inch - my windows are probably 25 years old -  will this crank handle fit this old of a window

Thanks for contacting us. The 3/8" dimension is not how deep the screw is, but rather the diameter of the hole on the handle itself. What is the diameter of the hole on your handle?
