The SmallRig 2144 Quick Release Clamp and Plate (Arca-Type Compatible) made of Aluminium Alloy allows the user to adjust the tightness of the clamp by stirring the tiny screw on the lever meaning that it is also cross-compatible with most Arca type plates.
The plate is attached to the bottom of the camera or cage by screw(s).
The clamp features multiple 1/4''-20, 3/8''-16 threaded holes and thorough mounting holes on the bottom allowing the user to mount it on tripods, jibs and other devices.
