A few years ago I worked on C-5 Galaxy Cargo planes, and there was a similar device used to opperate the seat position locks. I remember playing with one of them one day and thinking what a fabulous pushrod it would make. There was absolutely no friction, smooth as glass. Of course, being military equipment, that little pushrod probably cost $10,000 LOL

But I always wondered if someone made them for this hobby. If they do, I'm a customer!
