This is SUNWAYFOTO the first Lever-Release Clamp. It's unique and very easy to install on and remove from the Platform. You only need to take two 1/4-20 camera screws to install the Clamp onto the Leveling Base ( the clamp central hole is non-thread). If you have attached a Quick-Release Plate to your camera, then you can experience the fast lock and release.
Mount hole: UNC3/8
