The UURig R029 Canon M6 Mark II L-Plate is Arca-type compatible on the bottom base plate, and multiple 1/4"-20 accessory sockets are found on each side of the plate to attach a small quick release plate, so you can mount the plate vertically as well from either side. The built-in cold shoe mount allows for a microphone or a small LED light that stays out of the way from the camera's tilting screen.
The camera mounts to the L-plate via its 1/4"-20 threaded mount, and the anti-twist lip and rubber gaskets inside the bottom plate prevent the camera from moving while attached to the plate. Access to the battery compartment is maintained with the machined area under the plate, which is also where the included flat wrench is stored. A removable hand grip is included to provide a comfortable way to hold the camera.
