A wall-mounted barn door guide is optimal for thicker doors, or for situations where you can't drill into the floor, like with concrete flooring, or original flooring in a historic home. 

This roller guide mounts to the wall and makes a u-shape, the bracket wrapping underneath the door and out to the other side. The minimum door thickness is 1-1/2", and the maximum door thickness is 2-3/4". For thicker doors, see the Industrial Heavy Duty Roller Guide. This guide is finished black powder coat on solid steel with a black nylon wheel. Screws are included. Review the spec sheet for technical details and measurements.
