Review on 🚪 SMARTSTANDARD: Silent and Smooth Adjustable Sliding Solution by Elder Unogu

These roller guides have a great design. door unless you make sure the flat surfaces on the head are parallel to the surface of the door. Plastic rollers with a slightly larger diameter would have prevented marks on my new door. Overall this is a nice addition to any barn door setup. Tighten the screws to avoid damage to the door. I would buy them again for future barn door installations.
