Opening it fully to 180° is required to remove the plate.

I use their lever clamps on tripods (my bigger one has two, one on the leveling base to let me rapidly switch from ballhead to gimbal head, the other on the head itself). I’ve never had a scare with them. I do use a screw clamp in my monopod head, because I frequently carry that on my shoulder with a lens mounted, and there’s a reasonable risk of a lever catching on a backpack strap and getting pulled fully open. But otherwise, I prefer the ease and speed of a level clamp.
Thanks for the recommendation of RRS. Still doing homework, so it could be a while before I make my decision. I use the Acratech GP-s Ballhead. Love it, except for what happened. I've had it since 2018 and it has served me well. L bracket doesn't have a safety screw on the bottom so I may also look for a plate that does. Appreciate the advice.
