Airstreams and other trailers with sliding pocket doors have nylon roller carriers that must operate smoothly in the track.  When they get worn or broken they can be repaired with this roller and plate.

Our roller carriers are an upgrade from the original because they have ball bearings and a higher weight capacity of 150 lbs (more than enough), yet they still have the same 3/4" wheel diameter.  They are also height-adjustable for fine tuning.

The plate is screwed to the top of the door an the wheels go in your existing track.
