These reels are the very same reels that RMGI uses to load their 2" recording tape. Each reel has a profession solid back flange and a three windage hole front flange. These are heavier duty than the 1/2" or 1" reels, having flanges that are almost twice as thick for reel stability and resistance to bending. Each flange is attached onto the precision NAB hub with six screws. Each comes in a white foldup box with hub support. Made in USA.
