Promaster 6160 quick release plate
Second one I bough, great product
Well designed and easy to screw on and off with fingers. Great add to my PH-111V head.
I use a number these attached to spotting scopes and a binos adapter for quick attachment to a Promaster XC525 tripod. Provides a solid attachment with no play when optics are attached.
Does what it is supposed to do.
Works as advertised! Easy on and easy off. I have one on spotting scope and camera so I can change from one to the other in a few seconds. Very solid.
