Abstract: A roller system is disclosed that includes a roller axle with a longitudinal axis that houses at least a portion of a latch assembly. The latch assembly includes a latch with an exposed portion that moves substantially orthogonal to the longitudinal axis. The system also has a roller assembly that removably fits around the roller axle and has a latch catch. The system has two configurations: (1) a locked configuration, where the exposed portion of the latch obstructs the latch catch from sliding, thereby locking the roller assembly onto the roller axle; and (2) an unlocked configuration, where the exposed portion of the latch is moved towards the longitudinal axis, thereby allowing the latch catch to slide past, separating the roller assembly from the roller axle.
