The CRS attaches to a standard L-bracket and adds about 1.25" for your tethering cable. It also has a small locking bar to "lock" your cable to the spacer. This is great since any tugging on the cable can easily damage your camera's ports, a very expensive fix by the way.
Vertical orientation. The CRS firmly attaches to your L-bracket for stability.
Horizontal orientation, not much change but cable is firmly attached.
