Hi there!
I have multiple windows in which
1. the lock handle comes off. In all cases the locking mechanism works fine when you insert the handle and turn it, but the handle routinely comes off
2. the crank will open the window but not fully close it for locking. The window has to be pushed closed from the outside or pulled from the inside which is not easy!
My goal is to get replacement parts which I am sure I can install. Just want to make sure I am getting correct parts
We should definitely be able to supply these two parts for you. Starting with the lock, you have an older style that's no longer in development, but we do offer a few modern parts that should work just the same, depending on size. Look at our 38-095, 38-096, 38-138, and 38-139 to start out. We have detailed dimensions on each product's store page that you can use as a reference.
Concerning the crank operator, we have two potential replacements: either the 39-253RB and 39-253LB, or the 39-438B and 39-439B. The only difference between these two pairs is the design of the guide at the end of the arm, which I cannot currently see. I recommend watching the video below for a more comprehensive description of what I'm talking about.
