Abstract: A vacuum hub for tape reels and capstans is disclosed. The hub consists of two hollow parts each part having a ring of spaced projections thereon. The width of the projections being less than the width of the spaces between the projections. When the two parts are secured together with the projections of one part inserted into the spaces of the other part a series of spaced apertures is formed extending from the interior of the hub to the outer surface.
