I am looking for a Truth dyad casement operator. The part numbers stamped on the arms are 40352, 30905 and 31401.

Hello,
Take a look and compare the operators and sash locks that we've related for you to undamaged versions from your windows to see if they match up. Thank you!

What replacement truth dyad casement operator was relayed to Grand Junction, CO who posted on 713/21? I have to replace both the right and left dyad casement operator for my original windows and they bear the same numbers.

Hello,
Have you seen the related 39-171 and 39-172 operators that we originally recommended in this thread? They resemble yours but you'll need to confirm the dimensions and the end of the link arm that attaches to the bracket matches ours. Thank you!
