Abstract: An assembly is presented. The assembly includes a rotatable cylinder including product-holding members positioned on the circumference of the cylinder. Several cylinder passageways are deployed within the cylinder, which provides fluid communication between the product holding members and a vacuum. As such, a suction force may be applied from the vacuum through the cylinder passageway to the product-holding member. A locating pin is deployed on one end of the rotating cylinder. The locating pin enables rotation of the cylinder and a positive stop of the cylinder in an aligned position. The locating pin works in conjunction with an O-ring so that vacuum is only applied to one cylinder and one set of product holding members when the locating pin is locked in the positive stop position.
