Superstar mounts inside a base cabinet and allows storage of appliances on a spring action shelf that easily lifts and locks into place level with the counter top. Heavy mixers can be handled easily by the chef and since Superstar acts as its own counter top, the appliance does not diminish valuable counter space. Two lockings catches secure the mechanism in the open position. When finished, simply lift up on the shelf to release the catches and gently push the system back into the cabinet. Epoxy coated steel construction. Unit includes one left hand mechanism, one right hand mechanism and two heavy-duty springs. Shelf not included.
