Simonton Window Spline Size

I also purchased 39-375 to replace the broken handle on a Simonton window. The diameter of the inner star-shaped recipient for the axle was 11/32 for the part I bought from you, and 0.307" according to my caliper (closest fraction of an inch 12/32?) for the one on the window, so part 39-375 was too small. I am not asking for a refund, since I simply made my best guess and y'all did not misrepresent anything. However if you know of a crank handle that fits a _slightly_ larger axle, please let me know. Thank you.

Thanks for reaching out to us. Sounds like you might need something with a 3/8" spline. This is a relatively uncommon size but not unheard of. Before I recommend anything, can you show me a photo of the old handle and the operator it goes on? That will allow me to better understand what you need and whether anything we sell can work as an alternative.
