ABSTRACT OF THE DISCLOSURE A liner for the wear surface of a track which supportingly engages the rollers of a movable door such as roll-up doors used on vehicle load bodies adapted for use in hauling beverages. The liner is in the form of a strip of material secured to the surface of the track normally engaged by the rollers to reduce the wear incurred on the track by rollers engaging the track especially during over the road movement of the vehicle when the rollers vibrate or move a small increment of movement against the track with the wear liner eliminating the formation of a recess or hole in the track formed by engagement of the roller therewith. The liner may be a thin strip of stainless steel or a strip of ultra high molecular weight polyethylene or equivalent wear resistant materials.
