Review: Great and expensive replacement color matched. - We got these free windows, and one of them didn't have a window crank. Ambition windows would clean them all up and put them in our greenhouse for a building. And it worked perfect. There was some shavings up inside. I had to clean out with tweezers Once I set it on the window, it didn't go down all the way. I took a rubber Mallet and tapped on it, went down and fit perfect. Since I don't want it to come off. the color match perfect.
Review: Took jiggling to fit - Our Andersen window crank arm snapped off. I ordered this replacement and had trouble at first getting the handle all the way on. I looked into the handle and some of the metal channels had leftover pieces blocking the channels that were cast to fit the window part. I almost gave up on the handle but then decided to just try tapping/pounding into place (no tools). It went right on and the set screw was fine. The crank arm works great. The extra effort helped me get another arm that was loose, back on. Still rating 5 stars since it works like it’s supposed to work. Just a little painful to install.

### ⭐⭐⭐⭐⭐ So grateful for this product
*by K***T on December 29, 2024*

I am so grateful for this product we bought a 1950s house and one window was missing the crank, I was grateful that I could find it on Amazon. It’s a very good quality. The handle quality is amazing. It fits onto a star shape bolt that it cranks with, the color matched perfectly. I had to replace one that was gone. I didn’t even know what was originally there. I am so grateful that this product works so we can open the window. I could not believe that we could find our replacement part for such a good price and it was a great value for the money money
