Hello! Thank you for reaching out to us. We sell the 39-301 Andersen folding handle which is designed for a 3/8" diameter spline. Look over the specifications and see what you think. Just note, we can't promise this handle will give you the needed clearance for your shades. Most window manufacturers don't consider them when they design their hardware, unfortunately. I am sorry for any inconvenience. |
