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.

Ok, but flashing was not removed from inside of gear casting.
Product seemed nice at first, nice heft to it, good paint, knob moved easily. However, flashing from the casting process of the gear had not been cleaned properly, leaving debris and oversized teeth inside the 3/8” fitting. Because of this, it did not fit on my crank gear. This was easily remedied with a small screw driver and a properly sized grinding stone on a Dremel tool, and it fits now and works well.

Windows cranks
I bought these. They were not the exact same ones that I had they worked for a little while then came off not sure if it’s because they’re not the exact match or if it’s the quality.

Great Replacement Handle.
The handle was perfect for the 1986 Andersen Casement Window. Somehow I lost the original handle. Fit great and even matched the original color. Glad I was able to find this product.

This was a perfect fit for the patio door. Cost a lot less than calling someone in to replace the handle.

Amazing, there is a little screw that allows you to adjust to the size of the window operator,

The hole for the threaded screw has a burr (hole drilling leftover) that ENTIRELY prevents product from being inserted onto the mating window spline. 2 handles came in this package, both had this problem. Really, factory? This is such a basic error, super frustrating.
