Truth Dual window crank arm

Question

I believe the correct replacement for this original crank arm is 39-253LB. Please confirm, I originally ordered the wrong part, and want avoid another incorrect order.
The orginal hardware has 2 different ID numbers on each arm (41011) on the longer arm and (31876) on the shorter arm.

I agree, our 39-253LB looks like a great match. As long as the dimensions match up and as long as the slider at the end of the arm matched our 39-529 then it should be compatible with your window.

If your old cover can't be removed then you'll also need our 39-451 cover/handle kit (sold separately).
