The Z-Rail Rod Lock attaches to any  Z-Rail   and gives a 15mm rod port along the side of the Z-Rail. You can use this to mount the  Axis Mini  when using a regular Z-Rail oriented across the front of the camera. You can also use it to mount any 15mm rod, articulating arm to your Z-Rail. The Z-Rail Rod Lock tightens to the Z-Rail using a quick release ratcheting lever. Set to the side of the clamp is a 15mm rod port that also tightens and loosens with a quick release ratcheting lever. Zacuto dovetail accessories are adjustable to work with Z-Rail, NATO, SWAT, RED, PICATINNY, and WOODEN CAMERA rails.
