Vinyl window casement operator unknown brand
Hello! Your operator appears to be a match for our 39-089 and 39-090. Look it over and let me know what you think.
These operators don't connect to the sash via a track, though. These clip onto brackets like our 39-514 and 39-513, which just screw to the bottom of the sash. Can you clarify exactly what par tthis track is?
I'm actually not sure, I've never tried using it with these operators. The 39-089 will certainly attach to it without issue since it has the same peg, but you're probably going to have to drill new holes in your sash for it to mount.
If that does end up being necessary, just be very careful when drilling into a sash like this. The last thing you want to do is hit the glass.
The operator attaches exactly as you described: the bracket screws to the bottom of the sash, and the operator snaps to that bracket. No rollers or track are involved at all with this kind of hardware.
When you looked over our operators, did you notice any significant differences in size? There are some older models that have a differently sized link arm. Ours is 5" long, which is the most common size, but in the case that you have something different it may be causing the issues you're experiencing. In such a case you may need to remount the bracket's position in the sash to compensate for the new size.
We do not have an instructional sheet for this setup, no. These are pretty straight forward: the operator screws to the window frame and the bracket screws to the sash. That's really all there is to it.
Like I mentioned before, back on the 3rd of this month, the 39-089 is specifically designed to work with the 39-513 bracket. Since your old bracket is missing then that's really all I can tell you with confidence. If you don't think that the 39-513 will work, then you need to find the old bracket so that you can determine what will.
To reiterate, without the old part to use as a reference, all you can do is guess. My best guess is the 39-513.
Your only options at this point is to either give the 39-513 a shot or try to find your old bracket so that you can confirm beyond any shadow of a doubt what you need. That way you don't have to guess at all: you can just look at the old part and pick accordingly.
