This crank arm somehow became detached in the wind. Do I need to replace or how do I fix? Thank you. (wright window)

It all depends on the length of that long arm. If it measures 9-1/2" long, you should take a look at our 39-027E and 39-028E single arm operators. If not, let us know, and we will suggest another part for you to look at.
