Promaster 雙頭螺柱 1/4"-20公轉3/8"公 - 黃銅

I needed a way to mount my smaller light to a heavier stand, and this brass adapter threaded on perfectly without any wobble. The two different thread sizes on one piece saves me from carrying extra adapters in my bag.

Brass feels solid in hand, not flimsy like some of the cheap adapters I've had. The 1/4"-20 to 3/8" threading is machined cleanly, so my light and grip screwed on without any wobble. Been using it for two shoots now and it hasn't loosened once.

Finally got around to swapping out a mismatched softbox mount and this little brass adapter sorted it in seconds. The 1/4" to 3/8" combo is exactly what I needed for my light stand, and the threads feel solid and precise when you tighten it down.
