Casement Hardware Help

Hello,

We can't be sure without seeing your operator with the window open so that the entire assembly is visible but I see that you've purchased the Roto 39-091 operator and 39-224 handle in the past. 

You've also purchased the 38-139 lock but double-check that the specifications, including the locking fork projection, match your part. As for the guide and locking handle plate, see the 39-265 and 38-158. Thank you!
