Casement operator

Thanks for posting. It's a bit difficult to make out the style of the link arm in this picture. Could you show us a top-down view of the operator, either removed from the window or at least with the arm in clearer view? That will help us identify possible replacements. Many thanks.

Sure, you can send an email to help@swisco.com. Just be sure to include your discussion reference #, D138370, so we know who to reference the picture to. Many thanks.

Perfect, thank you! This looks like our 39-141 at first glance, but it could also be the 39-138. The major difference between them is the size of their arms. Look them over and let me know what you think!

Sure, you want to measure from the center of the wheel at the end of the arm to the center of the gear in the base. If yours is 8-1/2", you may still be able to use our 39-138, which is 9-1/2". That extra inch may not make a difference, but even if it does it should be easy to compensate for.

Thank you! This definitely looks closer to our 39-138. It may be off by less than an inch or so, but I think it will still be fine.

Awesome! Let us know if you need anything else. Thank you for considering our business, we really do appreciate it. 

Thanks for getting back to us! I'm not sure what clips your screens used before, but one common combination we like to use is our 70-180 plastic clip with a 33-020 screw. Look these over and see if you can get this combination to work.
