Please tell me if I can replace this Marvin window crank with a T type handle? I think 3/8" Thank you, Pam

Hello,

Take a look at the 39-108 T-handle that installs on a 3/8" diameter operator spline. You may also want to confirm your spline diameter since 11/32" is more common than 3/8", which would require the 39-102. Thanks for posting!
