The Kirk BL-D500N L-Bracket for Nikon D500 is a custom-made aluminium L-Bracket that means that you can quickly change your camera from horizontal to vertical & vice-versa without having to adjust your tripod head. Furthermore, the L-bracket helps to protect the camera body & keeps the weight of the lens & body over the tripod's centre of gravity. It is compatible with ' Arca-Type' heads.
