C-40 Arca fit perfectly into my manfrotto travelling tripod.
So robust, secures camera to tripod head without chance of popping out any more.
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!
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 didnâ€™t like the clamps that come with heads made for such a compact tripod.
It was very easy to rebuild my Manfrotto Befree Advanced tripod with this clamp. It matches the tripod perfectly. Both with regards to function and looks. It is of high build quality and finish.
