Review on SmartSmith Sliding Adjustable Bearings Upgraded by Chris Fisher

I had to customize the barn door kit to suit my application. Since I removed the groove that the included door track went in, I used these roller guides to fix the problem. The only thing I did differently was attach the rails firmly to the wall, but put the screws in the base into the rail's slot. Otherwise the conductor would end up crashing into the wall. I installed them on carpet and the problem was in the carpet. In any case, moving the screws to the floor worked great. The bike path is very smooth.
