Thanks for writing in! I believe you may be able to use the 39-138 Single Arm Crank Operator; the opposite handed version is the 39-139. Although, to determine that these are the correct replacement, you'll need to carefully review and compare the measurements. The most important measurement being the length of the arm.

Both of these operators are compatible with the 39-114L Crank Handle.
