LH 30470 20755 40471 Truth casement operator

A handy person from Forest Lake Mn says:
Hi, my windows are NORCO "1990". The long arm has a pn: LH 30470 which is 9.5" long from radius end to edge. The short arm has a pn: 20755. The body has a pn: 40471 (Truth). If this works I would need RHT and LH cranks.

Thanks
John

Hello, John. I believe your operator is a match for our 39-155 and 39-156. Look over our dimensions to confirm and let me know if you had any questions!

The short arm (Rht) side is 3-13/16, correct.
The long arm on the left is 10-3/4 from the (end) of radius to the pictured hole. Not the center of the radius or pin.

Thanks for clarifying, John. I'm afraid we don't have an operator with that same exact measurement. To my knowledge, Truth never made an operator with a long arm with that kind of difference. At this time, the 39-155 and 39-156 are still our best options.
