Alternatively, you can conveniently mount a 15mm rod, articulating arm, or Zacuto ZUD in perpendicular orientation to the Z-Rail. Two 90° Rod Locks placed on the same rail can be spaced for properly mounting 15mm LWS accessories without the need for a baseplate. Z-Rail accessories are also compatible with NATO, SWAT, RED, Picatinny, and Wooden Camera rails.
