What was on the bottom of my Gitzo's center post fell into a stream in the Wind River area. After that, nothing prevents the center post from slipping out of the tripod when I detach and slide it. Since he left me I couldn't even see what he looked like and I couldn't remember because I don't use the hook. I bought this to replace it. I'm pretty sure this Gitzo hook is ok, but according to the description it fits Gitzo Series 2 tripods. It doesn't fit my Series 2 (GT2545T). The screwed part is too small. I returned it and bought the one that was claimed to fit the B&H which is a completely different design and has a larger screw size. It now fits and holds the center post in the tripod.
