A channel device to hold a sliding door at its bottom. A U-channel beam attached to the bottom of the sliding door confines a roller bearing attached to an angle bracket on a door frame at the open end. The sliding door bottom is maintained adjacent to the door frame and the floor with the roller bearing traversing the U-channel beam. A large sliding door, such as a barn door, can thus be kept manageable for closing and opening. |
