A rotatable spool, such as a reel of magnetic tape, can be held tightly at a hub axial position and loosely at a second axial position beyond the previous position by using the metallic plate of the reel for holding the reel. In the first position a magnet through the plate positively holds the reel in position. If the push rod is axially actuated, the reel is separated from the magnet and a lower force such as a small magnet mounted to the rod, could hold the reel in position for a second operation, such as in a manufacturing process.
