Good afternoon. I have Wright Windows, aluminum, and need two "T" cranks. Can you tell me if I need to fit an 11/32" or 3/8" spline.

Thanks

I'm afraid I can't confirm the diameter of your handle's hole. Wright brand windows have been known to use both sizes. You will need to measure the old handle as carefully as you can to determine which one to go with.
