This CAMVATE Mini Ball Joint Extension Arm with 1/4"-20 Mounting Screw and a red locking lever provides an articulating extension arm for attaching to the 1/4"-20 mounting holes on your camera or camera support. Each end of the extension allows for 360° rotation and approximately 180° tilt adjustment. One end of the arm has a bare 1/4"-20 threaded screw, and the other end has a thumbwheel. The thumbwheel tightens against your accessory, preventing it from twisting loose.

Q: 2. Hi All, Can anyone help me. I was wondering if anyone has used this with the MeFOTO PMU50 Quick-Release Plate? Will it work?

A: I bought these because the plates i bought didnt have the fold out ring to grasp to undo. These u dont need a penny to tighten or undo. For me its a no brainer. Extra cost but to me worth it.

A: If I'm not mistaken this screw is nickle plated -- maybe chrome but more likely nickle.

Q: 8. Does the D-ring lock to one side so that it doesn't swing down and get in the way when you're trying to seat the plate in the head of the tripod?
