Prime-Line H 3966 Spline Socket Crank Handle, Stone, Smooth 360-Degree Operation (Single Pack)

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.

A proper replacement for fixtures on vintage Andersen windows. Well-crafted and reliable.

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.

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.

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.

Matched my window perfectly. Came on time and hassle free. Thank you!

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.

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