ThisBates Line of Casting Reelsis a true marvel of modern ingenuity and craftsmanship. Each reel begins as a solid block of 6061-T6 bar stock aluminum and is cut on our 9-axis CNC machine bringing each shape and specification to life with the highest level of precision technology can achieve. On Bates Reels there is only one plastic part on the outside of the reel and that is the casting adjustment.
