Precautions when installing

●Do not damage the groove in the rail. If damaged, rollers will not run smoothly. (When making holes with a drill, fill the groove with a plastic pipe or similar materials to avoid damaging the rail groove. Also be sure to screw straight.)

●Make very sure that chips and dust do not get inside the rail when making holes in it and during installation. If they do, remove them using an air compressor or some other means.
