Stud for LH 39-220B

Quick Learner from Oak Park IL
I am need to replace my current operator the the LEFT HAND Encore Dyan operator (39-220B). I know I need a stud to go with it - can you confirm which of the two I need to get : 39-545 or 39-546?

Thanks

Hello there. Either the 39-546 or 39-545 bracket could work with the 39-220B. A lot of it depends on whether the bracket is facing upwards or downwards, which depends on the sash design. If it's facing downwards, it likely is the 39-546; but if its upward it could be the 39-545. Ultimately check what's on your sash to confirm. Also note that if the old bracket is undamaged you likely could just reuse it. Let me know if you have further questions.
