Works Great

Fits my Pro Media Gear monopod perfectly. I am very happy with my purchase. I did get the "special" screw to attach it to my monopod however, it still needed a thread adapter to fit properly.

C-40 Arca converting from Manfrotto

Super Smart.
C-40 Arca fit perfectly into my manfrotto travelling tripod.
So robust, secures camera to tripod head without chance of popping out any more.
Thank you,

C40 Arca-Swiss clamp

It works and is well made. The only problem is the $9 for the Manfrotto anti rotation inserts - very expensive for what really are

The stock photo doesn't convey how heavy-duty this clamp is all around, including even the threaded insert. The build quality is really first-rate. I was debating whether I needed the C60 and its additional length, but that would have been overkill for me, as the C40 has more than enough holding power and is a good length, and the really robust 1/4-20 threaded insert is plenty strong enough. Also, the adjustment range of the moveable jaw is quite broad, so this clamp should fit just about any Arca-Swiss-type plate. With the current pricing on this clamp of just $30, it's a tremendous bargain, and I've already purchased a second one. If you need an Arca-Swiss clamp, this is absolutely the one to get!

Don’t Let the size fool you.

Same PMG quality in a smaller size. Works well with a table top tripod like the Feisol TT-15 and the ball head of your choice. I just didn’t like the clamps that come with heads made for such a compact tripod.
