Promaster Dovetail 平板夾具

Got this to hold my tablet on a tripod for filming, and the rubber padding inside keeps it from sliding around even when I adjust the angle. The two ¼"-20 ports made it simple to swap between the clamp and a quick release plate.

The dual ¼"-20 threaded ports let me mount my tablet to both a tripod and a flex arm without adapters. It clicked into place firmly and hasn't budged during my time-lapse sessions.

I've been searching for something to hold my tablet steady on a flex arm for video calls, and this clamp finally does the trick. The two ¼”-20 ports mean I can swap between the arm and a tripod without unscrewing anything, which is way more convenient than I expected.
