Garage door rollers are a rod-and-wheel system that connects the actual garage door to a set of tracks, allowing it to open and close swiftly and smoothly. Rollers suffer a lot of wear and tear as they do a lot of the work in opening and closing your garage door. They do require periodic replacement because of this.
