Specially designed for use with the XLCS Micro Cage, this 15mm rod will screw directly to the face of the cage in 2 locations via 1/4"-20 threads. A cross section of holes near the threaded end will allow you to securely tighten/loosen the rod.
 
With the 15mm rod in place, you can easily fix a single-mount style follow focus wheel to the cage while maintaining a compact settup. Theis also works great with focus motors if using a wireless settup or for gimbal use.
 
The rod is 100mm (~4 inches) in legnth--however, with multiple rods you are able to double or tripple the length by threading them on to eachother.
