This ~20 year old Viking window is missing the roller assembly. See attached photos of where one is missing, and another of what it should look like.

You may want to start by taking a look at our 87-201 sliding window tandem roller. See if our measurements match up with yours. If they should be different, get back to us and let us know how.
