Tightness of the clamp can be adjusted by stirring the tiny screw on the lever so it is also cross-compatible with most Arca type plates. The plate is attached to the bottom of cameras or cages by screws. The clamp features multiple 1/4-20 3/8-16 threaded holes and thorough mounting holes on the bottom so you can mount it on tripods jibs and other devices.
