[0.95 lb] Works great for mounting a Quantum Q Flash to a soft-box. This allows the soft-box and the speed ring to be supported by the tripod and all the weight is not put on the Q Flash. The Q Flash is then attached to the ring and it does not seem to be a problem for the flash to sustain its own weight.

[Strip] I usually use westcott softboxes, but found a special with impact that included a free grid. For connecting the box to the profotos, this worked perfectly

[0.95 lb] More cost effective than the profoto ring but still a quality piece of gear with a stable connection.

[0.95 lb] Really isnt a whole lot to say other than it works just as expected. Using this with their 2x3 softbox on an Acute setup.

[Metal] These rings are of very high quality: I recommend that you consider them as an alternative to the Profoto and Chimera rings. It use to be that third party photo products were inferrer to brand names. But I have seen a steady improvement in quality and design from third party vendors in recent years. As a college educated full-time NYC photographer for 40 years I can attest that they perform equally to the more expensive speed rings. They work with chimera, profoto and impact soft boxes. *Also check out the newer Impact Duo soft boxes; Decent products at a very palatable price, I have been �replacing my older worn-out high-end boxes with the impact line.

[Metal] A must for Lightbox attachment

[0.95 lb] I was looking for a specific piece for my flash and couldn't find it. I asked a sales person for help and he pointed out this speed ring. WHAT A GREAT SUGGESTION! I can now use my current soft boxes on both my flash and studio stobes! Thank you.

[0.95 lb] I needed a speed ring for an off-brand softbox for my profotos and this did the job perfectly

[Strip] I was worried when other reviews said they don't fit but the two I just received both fit both B1's and B2's and hold the strip boxes just fine.

[10] I was looking for something like this for a while. I purchased a Profoto B1 kit from B and H last year to replace my old Calumet strobes I had for a long time. This impact speed ring will make it possible for me to use all my Calumet soft boxes and beauty dish I have collected over the years. Only thing I had to do is drill the holes slightly bigger so the rods fit in the holes. I'm an happy camper now. This will save me a bunch. Now I don't have to buy more new stuff.??. Thank you B&H for always having great stuff.
