Garage Door Rollers
In addition to cables, a garage door also has rollers. While you do not notice the rollers right away when looking at the garage door, they are another part that helps the garage door open smoothly. Doors have various numbers of rollers. Generally, the more rollers a garage door has, the quieter it is to operate. Most garage doors have 10-12 rollers. Like other components that help move the door, the rollers attached to the garage door can wear out quickly if they are frequently used. The rollers may come off their tracks or make an unusual squealing or grinding noises. In order to prevent problems with the garage door rollers, they should be inspected periodically by a professional who is experienced in servicing San Luis Obispo garage doors.
