1984 window hard to turn small crank. Looking for a longer handle or ADA handle.

Thank you for reaching out to us. Can you show us a photo of your operator with the window open so that the arms that move the sash are fully visible? Once we can identify the operator, we can determine which handles are compatible with your assembly. Thank you!

Thanks for the additional photos! The operator shown here reminds me of the 39-027E and 39-013. However, they have an 11/32" spline which is compatible with the 39-205, 39-114L, and 39-114 handles. Can you double-check the hole diameter for us, just to be safe? 

We sell the 39-224 and 39-230 but these are designed to fit a 5/16" hex gear bore. The 39-274 is our only other option. Take a look and see what you think.  

Certainly, our return policy can be found here just in case. All orders can be placed directly on our website at your convenience!

We don't sell a T handle for a 5/16" spline. The 39-102 T handle that fits an 11/32" spline appears to be our best option. However, we don't have this in a light bronze color option, unfortunately. I am sorry for the inconvenience.
