This is a very handy little item, just fit it on top of your light stand spigot and tighten the knob on the side, then attach any other item (within its weight limits) with 1/4" opening x 20 thread on the top.
Sturdy ball.I am using this together with STROBEPRO DUAL PISTOL GRIP ROLLER STAND.Pleased with how the pivot is holding my camera.Steady as it can hold the weight without issues.( I have a CanonT6S).In fact I have a second one which I will mount an overhead camera for YT videos.
This is a superb light and stand! I love the how you can easily adjust the Kelvin and light percentage, and the remote is excellent. I was amazed at actually how much power this light gives off ( I really wasn't expecting that ), and the barn doors really help focus the light where I want it. Everything arrived in perfect condition and the quality is top notch! I am a novice film producer and have a lot to learn about lighting, but between this and a reflector I have it will be useful for many situations. Highly recommend!
