### ⭐⭐⭐⭐⭐ Great and expensive replacement color matched.
*by K***G on October 1, 2024*

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.
