صندوق إضاءة Fotodiox Pro، حلقة سرعة ولوحة عالمية لومضات بقطر 3-6 بوصة بدون قاعدة حربة - لوحة حلقة سرعة 7.75 بوصة لصناديق الإضاءة القياسية

I was worried about compatibility with my older softbox, but the 6-inch outer diameter fits perfectly and the all-metal construction feels solid. No wobble or cheap plastic parts here.

For the price, this all-metal speedring feels solid, and the 6-inch insert locks into my softbox without any wobble. I was worried about compatibility, but it connected to my strobe's speedring plate on the first try.

The metal insert fits perfectly into my standard softbox and feels solid enough to hold even a heavy strobe without any wobble. I was relieved to find the 6-inch outer diameter matched my modifier exactly.
