Promaster Dovetail QR Clamp Kit

The 3/8"-16 thread mounted perfectly on my monopod, and the clamp locks down tight with zero wobble once the dovetail slides in. It also came with the 1/4" adapter, which was a nice bonus since I switch between cameras all the time.

I attached this to my tripod head and the 3/8"-16 threads were a perfect fit, no wobble at all. The clamp locks down tight and releases smoothly, which makes swapping cameras on location much faster than my old screw plate setup.

The 3/8"-16 threaded port screwed onto my ball head in seconds, and the clamp locks tight with zero wobble. I've been swapping it between my grip and tripod for a week of shoots and it's held rock solid every time.
