[Easy to install] There is no groove on the door. Simply attach the two screws to the lower guide rail and pull the roller guide plate into place. [Excellent Durability] The sliding door floor guide is made of high quality iron, and the high temperature surface is coated with high pressure black powder coating to ensure corrosion. Easy sliding] The smooth bearing is easy to slide, and then the door is easy to slide. The bottom of the floor guide is flat, does not damage the door, and the floor can slide smoothly and quietly.
