The C-30 clamp was made specifically for the old-style Wimberley Head (WH-100 & WH-101). The new version of the Wimberley Head (WH-200) has a built-in quick-release clamp, eliminating the need for the C-30.

The added length of the C-30 (1.6" longer than the C-10) provides little added functionality for most applications. We recommend using the lighter and less expensive C-10 clamp.

We are still manufacturing the C-30 for those who wish to retrofit an old-style Wimberley Head, replace a damaged C-30, or have an application that requires a longer clamp.
