Is 39-388 The best fit?

Question

We previously identified the 39-387 as the operator closest to what would replace my existing stripped operators for 2 windows. As the photos show, I ordered the incorrect handed ones and was about to order the 39-388. While the length of the arm from the gears to the elbow joint look good, the length to the clip on the outer arm seems short. Does this small difference (seen in one of the photos attached) matter? Would the 39-172 or 39-318 be a better fit? Is there another? I can't judge how close in size the base is to my existing one or the the 39-388.

Your input would be helpful before I reorder. Thank you again!

I think the 39-388 is definitely our closest option. The 39-172 and 39-318 are similar, but the link arms are a different design and likely won't work as well.

Concerning the size of the link arm, that may very well be an issue. You may want to measure yours just to be sure. Now, you may be able to get away with a little bit of a difference, but if it does end up getting in the way you have two options.

First, and easiest, you would remount the bracket on the sash. The bracket is the piece on the sash to which the link arm attaches. If you move it back a little, it should make up the difference and all will be well.

If that's not possible for whatever reason, you could always just swap the link arms. You can do this by drilling out the link arm on the old and new operators and then installing the old arm on the new operator with our 62-014.

Let me know if you have any questions!
