I need to replace two window cranks (one RH and other LH) at my house. I see a few cranks on your website. How can I determine which is the correct one for me. Going by the number and positions of the fastening screws and their relative positions, the Model 39-016 appears to be the correct LH crank for me. How can I confirm that before placing an order?
Thank you.

Can you send us a few photos of your existing crank operator? We may be able to confirm for you that the 39-016 is the correct replacement based on your photos.

I need help to identify the correct crank to order to replace existing cranks. One is Right handed and another Left handed. Do I need measurements or anything else? The home where these are needed was built in 1979. I do not know if the images from your website attached are the correct ones.
I need your assistance.
Thank you.

Good Morning,
We need to see photos of your existing operator. We cannot tell what you need without seeing an image.

Thank you for submitting your photos.
Unfortunately the images do not show the internal linkage of the operator. The outside casing looks correct, but I cannot recommend an operator without seeing the inside linkage portion (including dimensions).

Here are some new views of the window cranks I have. All three pictures show the same crank. The photos sent early were for the other hand, but they are all the same type. Can you please now identify the correct part number for me?
Thank you.
Thank you.
