The RRS-OBA allow positioning of your optics balance point directly over the optic ball socket on the Granite Peak and 3L/V2 Tripod solutions. It has seven 1/4X20tpi female thread holes space 3/8" apart for balance point adjustments. It also has the proper KDC 60° bevel to slide into the RRS-Shoe and KDC-NanoPanhead. Almost a must for balancing binos. The singel 1/4X20TPI male thread will attach to the base of cameras, spotters, and most importantly will attach and spinlock to the base of the RRS-Bino Tower.
