Operator Replacement Guidance

A home owner from Washington, DC says:
All of the casement windows in my house have Truth dyad operators similar in size to SWISCO products 39-171 and 39-172. I want to install operators with folding handles in all of my windows but I could use some guidance as to which of your products are appropriate replacements.

Bob from SWISCO responded:

Thanks for posting. I agree these operators look like our 39-171 and 39-172. Just make sure the arm dimensions match up; let me know if anything differs. For a folding handle that works with these, see the 39-205 sold separately. Let me know if you have further questions.
