A roll-out shelving storage rack system includes a frame coupled with a shelf member. The shelf member includes a base support, a shelf support tray, a shelf, and a driver. The base support mounts to the frame, and the shelf support tray engages the base support and is movable between a retracted position and an extended position. The shelf engages the shelf support tray and is movable between a retracted position and an extended position. The driver is coupled to the base support and the shelf. Activation of the driver moves the shelf from its retracted position to its extended position. Further, when the shelf reaches its fully extended position, the shelf support tray moves from its retracted position to its extended position. The extension of the shelf support tray substantially and completely extends the shelf outside of the frame.
