3 Seasons Portch Window Crank

A handy person from Cedar Rapids, Iowa says:

Our house was built in 1966. We have a 3-seasons porch and one of the window cranks is totally broken. I have included photos of what the broken one looks like and what a fully functioning assembled crank looks like. The arms that open and close the windows seem to be fine. And the crank is 6" long. Please let me know what part I need or if you need more photos, I can take some more.

Thank you!

There are two possible replacements for this operator. You will have to carefully compare the dimensions we show to your own hardware to be sure. Check out our 39-074 and 39-280 and see if either of these can work for you.
