These are vinyl clad 4500 casement windows installed by NVR homes around 2002, I would like to obtain some replacement crank mechanisms as the gears have stripped. ID info is on one of the pics, can you assist?

Hi- thanks so much for posting!

We will need to see a photo of your window open as far as it will go so that we can see the entire mechanism. This will help us to better determine what replacement operator you will need.

I think it might be a Truth 9" - do you agree?

Thank you! It's tough to make out, but it appears to be a straight arm type operator. See our 39-028E and 39-027E to start out. Two important details are the length of the arm and the style of the bearing at the end of it. As long as those match up to the two I mentioned, I think they'll work great as replacements.
