Thanks for posting! Can you confirm the size of the hole, or "spline?" I believe it should be 11/32", not 3/8".
Start by looking at our 39-205, which is our most common 11/32" folding crank handle. We also c arry the 39-157 4" long 11/32" spline extension. They don't make a solid T handle/extension combo. You could possibly use our 39-102 T handle, if you cannot reuse any of your old ones. |

Truth brand casement operator handles usually have a spline size of 11/32", but I recommend measuring yours just to confirm that this is the case.
