C-30 Quick Release Clamp

C-30 Quick-Release Clamp ($100.00) - Length: 4.2"    What's Included

The C-30 clamp was made specifically for the old-style Wimberley Head (WH-100 & WH-101).

The added length of the C-30 (1.6" longer than the C-12) provides little added functionality for most applications. We recommend using the lighter and less expensive C-12 clamp.

We are still manufacturing the C-30 for use with an old-style Wimberley Head or in special applications that require a longer clamp.

Tongue-in-pocket Design
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.

Captive Knob
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.

Safety Channels
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 plates.
