SWISCO - The Replacement Hardware Authority

Window cranks

A home owner from USA says:
Can't quite read what it said on the unit but it looks like...6097p, 6498p, on the longer ones, and 6d97p, on both of the short ones. What don't make sense is the longer one is right and left crank so different numbers, but the short ones are also right and left but has same numbers.
What is worn out is the teeth on the crank gear, I don't know if you can help me.
Here are the pictures, Thank you Mike

Thanks for posting. Don't worry so much about the numbers printed on your hardware. Manufacturers change those all the time over the years, and we find that they aren't the most reliable method of identifying a match. You're better off basing your replacement options on more tangible details like design, size, and function.

Based on your pictures, I think our 39-387 and 39-388 may work for you. Carefully go over our measurements and see what you think.
