Truth operator

Question

Hello!
I need to replace a few Left and right dyad Truth operators. The total length of the arm to the rotating crank is 9 1/4 in. The top part (connected to the window) is 4". The other part connected to the crank is 5 1/2". I found a few products on your site, but they are longer than what I have. I am a bit sceptical if I could fit them into the existing opening in the window. Please advise if you have a product that matches one of mine.

Sure, I think we can replace this. See our 39-317 and 39-3178. The only issue is that the arms for these are a little smaller; the link arm is 3-1/2" to your 4" and the gear arm is 4-3/8" to your 5-1/2". It may still work regardless, but in a worst case scenario you could adjust the position of the connecting bracket on the sash.
