I'm having trouble getting the right crank handle for my crank-out casement windows (pair); I recently ordered 39-274, but the spline didn't fit over the crank receiver - too small. I've re-measured and think an 11/32" is right, but would ideally like the 39-274 item in that size if available. However, your website isn't showing that in the slightly larger size, and the only 11/32 cranks are configured a little differently, which worries me that the crank handle may not clear the window stool right below it. What you do have in the 11/32 cranks is this (you can see the style difference): https://www.swisco.com/Long-Crank-Handle/pd/Replacement-Window-Operator-Accessories/39-114L. I don't want to order this and have it not fit and then have the expense of returning still another item. Help me out here.
here is a pic of where the window crank handle gets inserted. As best as I can tell, the diameter is ¼". The crank I previously ordered was well-made and of good quality, but simply didn't fit over this part. So if there is a similar item with a slightly larger spindle (if that's what you call it) opening, that might work here.

Thanks for reaching out to us! I'm afraid we don't sell a version of the 39-274 handle with an 11/32" spline. If you're worried about the handle hitting the sill, we recommend you consider the 39-102 T-handle or the short 39-114 handle. The total "wingspan" for the T-handle is 2-3/8". Look over the specifications and see what you think.

Thanks for your help; I did find two handles that work in the meantime, and am happy with how they fit.
