Presuming that they're the same, I've got a post with several photos of mine with the removable metal sliders and their wheels installed. They'll give you an idea of orientation at least. These sliders can be completely removed/cleaned. They also have a rotating "catch" at the front end of the cabinet that is used to lock the drawers in place once you've put them in so that the drawers can't accidentally be pulled all the way out.
