I purchased and received a 4" Crank Extension, 11/32", Item #39-157. Unfortunately, the inside diameter of the female end is too small to fit over the male end of my existing window crank...but just barely. Do you have a 4" Crank Extension which has a female end that is just slightly larger? FYI: The male end will adapt to my existing crank with the set screw fully tightened.

Thanks for posting. The hole for the 39-157 is 11/32" in diameter. You said you need one slightly bigger, but not by how much. Can you tell me exactly what size you need? With that, we can see if a part is available in the size you need.
