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.

As expected
Works as expected. Ordered two, but had an issue with one not fitting properly. They replaced it immediately with no further cost to me.

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.

It was the item I needed
I like always how quickly Amazon gets their products out. The handles I ordered for my Anderson windows matched well to the broken ones, only they were a bit difficult to get on. Had to use a metal file to take some of the metal off around the holes for the screws. Was stopping the handle from slipping on. But eventually I got them on.

Exact replacement
Exact replacement handle for Anderson casement for me.

Screw too short
Although the handle is well built and fits perfectly the Andersen gear mechanism , I was forced to return it because the screw that should have secured the handle to the spindle is too short, this is not a minor issue because the handle will not stay in place , will not grip the gear and falls off!

Great fit.
Cranks fit great and matched our screen frames perfectly. Great price for a good product.

Perfect!
Our den has been missing 2 of these on the windows since we moved into the house! I didn't think of ever find any to fit since these Andersen windows are from the 70s but these actually do! I've seen a lot of reviews saying these don't fit their andersen windows, first you have to make sure it's the right size (duh), second loosen the screw that's at the bottom to ensure it has room to wiggle on, third you do actually have to push to get it on its not just going to slide on because then it'd have a loose fit. Anyways, super happy to finally have window cranks!

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

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

Not functional due to poor manufacturing
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.
