Just chiming in to ask if a super clamp with an actual ratcheting mechanism even exists. I own two of the Manfrotto's with the L-shaped "ratchet" handle and it does not actually have a ratcheting mechanism, nor is there one in any other brand of clamp I've ever seen that uses that word. So far I'm convinced there is no such product made, and every time someone links a so-called "ratcheting" clamp, it very clearly is nothing of the sort, but just a another clone of the Manfrotto I have. They are describing the style of handle, but it does not ratchet.
I really wish that manufacturers would use a different word to describe this kind of handle, as calling it a "ratchet" or "ratchet action" is totally misleading.
