Crack for Bow Window
The window was purchased at Home Depot back in 2002/2003.
In a couple of the pictures there are 2 cranks side-by-side to show how the one on the right is broken at the top.
Thanks for reaching out to us! Your crank handle can be replaced with the 39-226 Male Roto Folding Handle. Although, since your operator appears to be missing the black collar where the handle inserts; unfortunately, we do not carry the replacement for this piece. Many customers have encountered this issue and, as a result, the manufacturer changed the design of the operator.
That said, it may be a good idea to replace both the handle and operator completely. Replacing the handle alone will work for a while but it would only serve as a temporary solution.
I'm happy to provide you with recommendations for replacement operators, I'll just need to see a photo of the entire operator. I am especially looking to see a photo of the operator arm(s) and how the operator connects to the bottom of the window.
