Hello! Looks like you're showing us two different operators. Am I right to assume that the top operator is a replacement that you tried out, but discovered that the hole was too small? If I'm right, can you tell me the diameter of the hole on your original? I'd also like a picture that shows a clear angle of the installation screws on the top and bottom tabs. There should be either 3 or 4 screws altogether and I need one photo that shows all of them. Thank you! |

Thank you! We have two operators with a similar hole pattern, a straight link arm, and a 3/8" link arm hole. See our 39-194 and 39-378. These are designed similarly but have different dimensions in other respects. I recommend looking both over to determine which, if either, can work for your window. |
