That's not an NAB hub, that's an EIA hub.  The only reel
with an NAB hub on the other page you link to is the one
at the bottom for 1/2" tape.  We may be experiencing a
disagreement on the meaning of "hub".  :-) The EIA hub has
a 1/4" hole with three thin tabs on it, with the provision
for a drive puck a little bit farther out from the center
than the tabs.  The NAB hub has a 3" hole with three
wider tabs.  As far as I know, the diameter of the subsequent
hub upon which the tape wraps is not part of the distinction,
but I welcome informed correction.  :-)  I've got hundreds 
of tapes on low-torque spot reels and 7" reels, but I've
always seen them referred to as low-torque EIA reels.
