I don't know what unit you have. Those of us that are doing this modification do not have rollers. The bottom of my slideout is covered with darco (that slick, black, plastic looking material) and sits directly on a wear bar. When the slideout moves, the darco is in direct contact with the wear bar and eventually starts wearing out (usually on the outer edges); not a real great design.

My slideout now sits on UHMW strips instead of the darco. The wear bar is a similar material to UHMW. When the slideout moves now, there is very little friction and the darco material is not rubbing on anything.

I have not seen one, but I have read that some units actually have rollers; maybe yours.

Look here for photos and a better explanation. Post 5 shows a clear picture of the damage and the repair. Post 38 shows the wear bar attached to the trailer frame and how the slide sits on the UHMW after repair.

Here is a link to download a PDF of the repair with photos that clearly explain the problem and repair.

This thread discusses the difference between DIY UHMW strips or using the commercial product Slide Skis.
