Ideal for still photographers who want to attach a softbox to a battery-powered flash head, the Speed Ring for Bolt VB, Quantum Q & Lumedyne Series Flashes from Impact softens the output of the flash while ensuring the softbox won't stress or damage the head.The speed ring features labeled flex rod holes for effortless mounting of most rectangular, square, strip, or octagonal softboxes to a Bolt VB series flash head, as well as Quantum, Lumedyne and Norman portable bare bulb heads.
The sturdy all-metal ring rotates 360 degrees, thereby avoiding reorientation down time, while the self-locking outer ring prevents movement or slipping once the position of the softbox is set. Convenient 3/8' threaded accessory holes facilitate mounting your softbox directly to accessories such as umbrella adapters, articulated arms, or clamps.
