Abstract
The present invention provides modular sliding door rollers for use in sliding doors. The modular sliding door rollers have a major roller unit and one or more minor roller units modularly connected together in series. The major and minor roller units have a roller which is adjustable to extend out of and retract into the major and minor roller units by adjusting a roller adjuster on the major roller unit. Two pairs of partially overlapping and divergent roller axle slots are provided on each of the major and minor roller units to provide for extension and retraction of the rollers.
