Promaster 5500 황동 스터드 및 이중 스피곳이 있는 스튜디오 클램프

The double spigot gives me both 1/4-20 and 3/8 male threads in one clamp, which saves me from swapping adapters constantly. The brass stud feels much sturdier than the standard steel ones I've used before.

The brass studs and double spigot feel incredibly sturdy, and the allen key made mounting it to my flat surface a breeze. I was able to secure my studio light in under two minutes, and it hasn't budged once.

I’ve been using this clamp for a few days now and the built-in Allen bolts make permanent mounting incredibly easy. The double spigot gives me plenty of flexibility for positioning lights and reflectors exactly where I need them.
