Regarding window openers,
We need 8 mechanisms. 4 that open left and 4 that open right. The stamp is 30905
We also need 14 crank handles. The stamp says 45001
We need 3 small track. Stamp says 40448
If it comes in only white that that is fine. If the crank is shaped differently, that is fine too.
Thank you,
Robin
Hello, Robin. I'm pretty confident we can replace this. Now, yours is an older style that isn't made anymore, but I have a couple ideas of what you can do about that. I just wanted to pass these ideas along to my colleague Dave. He has a lot more practical experience with these than I do. Once we butt our heads together I'll get back to you ASAP and we can talk about our options.
Hey there! Tom Just caught me up with this. Now, we only have one operator pair that will replace this: our 39-317 and 39-318 (sold separately). These are a somewhat updated design, in terms of the shape of the base, but otherwise functions the same way.
There's one detail, however, that may prove to be a problem, and that's the size of the link arm. Ours are only 3-1/2" long (from the center of the hole to the center of the rivet). Just eyeballing yours I can tell that its longer.
So what can we do? Well, you have three options. The first is to try it out as-is. It very well may work without issue, but I have a feeling we won't be that lucky.
The second option is to remount the bracket in the sash. Do you see that triangular bracket at the end of the arm in your photos? That's what I'm talking about. You'd have to redrill new holes in the sash to mount it in such a way that it will compensate for the shorter arm. Your window won't open as far, but only by a couple inches. You shouldn't notice. Just be careful not to drill into the glass!
The third option is to swap the arms out. You'd put the old arm on the new operator. This is a little more complicated and takes more work, but let me know if you're interested and I can walk you through it.
