Replacing window crank
Hello,
If you could open the window and show us the arms that move the sash, that should help us determine which handles would work for you and how they install. Thank you!
I understand that you're looking for a replacement handle. I'm asking you to open the window so that we can see the entire assembly, which will allow us to identify your hardware and confirm the handle that you need. Once we know what handle you need, we can tell you how it is removed and installed.
Great, your operator looks like a match to our 39-315 and 39-316, which do use the 39-114L handle. The 39-114L is pressure fit on the operator's worm gear, so you'd just pull the original handle directly off of the base.
You could use our 39-205 folding handle as a replacement, which uses a set screw to secure the handle to the worm gear.
