The shuttle uses custom designed full pull out slides made from that painted aluminum extrusion and ball bearings as rollers. It should work. Maybe it is the paint applied to all the mating surfaces, or maybe the bearings are just a wee bit too small. Either way, the shuttle does not act like a drawer on ball bearing rollers. Instead it acts like a drawer sliding on painted aluminum slides without any ball bearing rollers. My wife probably won't be able to operate the slide with a loaded fridge on it.

The other negative is the handle has been changed from the photo. It now is like a toolbox drawer handle, except in reverse. You push the handle down to unlatch. You can't even get your fingers under the handle to pull once you push it down. I have to push the handle down with one hand and then pull on the webbing straps with the other hand to get it to come out. Once the slide is about half way out, you really need to support the full fridge weight as you pull to keep is coming out without too much drag.

They also deleted the handy rubber pads seen in the photo. You'll need those and you'll have to fashion those on your own.

Other than the low profile, flat top, and quality materials, the shuttle has nothing going for it and really shouldn't be offered for sale in the current configuration. Too bad, I wanted that low profile to work.
