The SmallRig 2960 HDMI & Type-C Adapter is specially designed for SmallRig cages and L-brackets for the Blackmagic Pocket Cinema 4K and 6K. With the adapter you can move the HDMI and USB-C port to a different position to prevent pulling on the cables. You can also attach the SmallRig 2930 adapter to the side of the camera cage with two screws.
