I need crank operators, 1 left, 1right for early 2000's crestline casement windows. All the numbers match for 39-172. The clip on end of 5" section is just a hole that a pin pops in. I have bad internet connection so I can't upload photos. Even the screw holes are the same as in pic of 39-172
Please advise.
Thanks, Bill

Hello, Bill. I'm afraid I'm not sure what you're asking. It sounds like the 39-172 matches the operator you're looking for, by your own description. Is there anything in particular you wanted to know about this part? Did you have any concerns that it might not work?
