Hand Crank for Window

Home Owner from Roseburg, Oregon
I have Best Built windows (BBI-1) that were built between 1995 and 1999, our house was built in 1999. The series:850 ; C-C40 ; MST: 3050. The inside opening of the crank is around 12/32 inches, it could be 11/32 inches. What part would you recommend me ordering. Your help on this would be greatly appreciated.

Double-check the diameter of the hole that accepts the spline. if it is 11/32", then you can use either our 39-114L or folding 39-205.
