Wimberley C-30 User Manual

The C-30 Quick-Release Clamp uses Arca-Swiss geome-

try. It is compatible with most Arca-Swiss style quick-release

plates, such as those made by Wimberley, Really Right
Stuff, Kirk Enterprises, Arca-Swiss and Markins.

It is not compatible with most Bogen, Manfrotto or Gitzo
quick-release plates.

The C-30 clamp is 4.1" long. It has three 3/8"
threaded mounting holes. The C-30 was originally designed
to convert the old-style Wimberley Head gimbal (WH-100) to
a head with quick-release
capability. The C-30 was the standard quick-release clamp
sold on the classic Wimberley Head (WH-101) until this
model Head was discontinued at the end of 2005.

Mounting the C-30 to the
Old-style Wimberley Head:

Remove any cork/rubber padding from the Wimberley
Head platform before attaching the clamp (this provides a
more rigid connection). It is not necessary, but it is recom­mended. To do this, simply peel off the cork (use a butter

knife or plastic spatula if needed). Use lighter fluid as a

solvent to remove any excess adhesive that remains on
the platform.

Use the enclosed hex key and fasteners to mount the
clamp to the platform of the Wimberley Head.

Open the jaws of the clamp by turning the knob
counter-clockwise.

You can load a quick-release plate by opening the
jaws of the clamp minimally and sliding the plate in
from the end (end loading), or you can open the
jaws of the clamp wide so that they clear the entire
width of the plate and then load the plate from the
top (top loading).

You will need to top load your plate if you have
safety-stop screws installed on your plate.

Quick-Release Clamp

Captive Knob

There is a captive screw in the end of the threaded stud of the
clamp knob (Fig. 2). This screw keeps the knob and internal
workings of the clamp captive, which means that the knob
should not unscrew entirely and come apart unexpectedly.
You should not need to back the knob all the way off the
clamp stud.

Note: For added protection during transport, we recommend
closing the clamp all the way to prevent damage to the knob stud.

Tongue and Groove design

The clamp has a unique hidden tongue and groove design that protects internal parts from dust and grit (Fig. 3).

The tongues are nearly twice as long as those on other Arca-Swiss style clamps. This added length counteracts
the tendency for the moving jaw of the clamp to tip backwards during clamping, thus keeping the jaws aligned
with the geometry of the plate. This also eliminates unwanted bending stresses on the stud on which the knob
rides.

Safety Stop Channels

Two shallow, finger-shaped channels have been machined into the face of the clamp from the ends, stopping
just short of the central 3/8” tapped hole (see Fig. 4). These channels allow greater forward-backward adjust­ment when using the optional safety-stop screws on Wimberley plates or on other compatible quick-release
lens plates that include this safety feature.
