Window crank operator

I don't think we'll be able to get you this exact operator, since it appears fairly old, but we will do our best to find an equivalent replacement option. Before I recommend anything, can you show me a picture of the link arm? It appears to be folded under your operator in each of your photos and I can't make it out. It's an important detail, so seeing it will help us find a good match. Thanks!

Perfect, thank you! Now, I wasn't able to find an exact match for this operator. There's a chance it may be too old. However I did find one that may potentially work, if with some minor alterations. 

See our 39-017. You'l note that it has two installation holes in the top tab, but my hope is that you'd simply ignore one and use the other to install it in the frame. You'll also see that the top to bottom hole center spacing is 5-1/4", not 5-1/2". I couldn't find anything like yours with 5-1/2". You may still get ours to work but it would require redrilling the installation  holes.

The hole in the link arm, which is one of the most important details, appears similar in size to your own. It's a 5/16" 18 threaded hole. I'm hoping they match up.

Let me know what you think!

Ah, that is a potential match. It still has the same 5-1/4" top to bottom hole measurement, which means you'll still need to drill a new installation hole, but I can tell you that the length of the link arm doesn't matter so much. The linkage in this kind of window has some play so you can get away with a difference. The most important measurement in relation to the link arm is the size of the hole--this one is 1/4-20 threaded.

There is another important detail to consider, and the main reason I didn't recommend this to begin with: the 39-350 has no left hand match. We did carry it at one time, but it was discontinued. We can only replace this side.
