Hello! The 39-268 does appear to serve the same function. It works a little differently than yours, though. It doesn't have the same guide, or track, that I see screwed to the face of your window sash. Rather, the 39-268 has a stationary bracket that screws to the face of the sash. When you crank it, the bracket slides along the arm of the 39-268 itself.
