Our clamps have a unique tongue-in-pocket design that protects internal
parts from dust and grit. The tongues are nearly twice as long as
those on conventional Arca-Swiss style clamps. This added length counteracts
the tendency of the moving jaw of the clamp to hinge backward during
clamping, thus keeping the jaws aligned with the geometry of the plate. This eliminates unwanted bending stress on the threaded stud.
A captive knob is designed in such a way that the user cannot accidentally remove the knob during use. There is a stop screw located on the end of the stud to keep the knob from unscrewing from the threaded stud.
Two shallow channels extend from the sides of the clamp and stop just
short of the central tapped hole. These channels allow greater fore-aft
adjustment when using the safety stops on Wimberley quick-release
