39-301 page does not list spline size.
If 39-301 does not fit, do you have a folding handle that does?
We need blind clearance, and Anderson standard "Compact" handle has very short lever arm, making it hard to crank windows open and closed.
Thanks!
Does 39-301 folding handle fit 11/32" spline used on 1991 Anderson casement windows?

Thanks for reaching out to us. The 39-301 handle has a 3/8" spline size, which is standard for all Andersen-brand casement window handles. Please note that Andersen and Anderson are two very different companies that use very different parts. I know this is very confusing, since they're only one letter off from each other, but I think that might be why you're having trouble finding this.
If your old handle has an 11/32" spline then you likely have a Truth-brand operator, which was commonly used on Anderson windows (Anderson with an "O," that is). See our 39-205 for our Truth folding handle.
