Gary Fong GF-LSC- Collapsible Speed Mount for Camera

Q: Does it fit with the yongnuo 565ex??

Please see this video on how to test for fit: https://www.youtube.com/watch?v=rDNRqASadhE

Q: will this fit nikon sb-600

It should due to the adjustable strap it can expand or shrink to fit a larger or smaller flash unit. My Canon 600EX-RT is one of the larger flashes around and it can fit perfectly.

Q: Shouldn't this product include a universal mount? The silicon grip band that goes on the flash first? My unit did not include the grip band.

Hi from Gary Fong. The previous generations had a grip band, the generation five does not need it. Please see our fit guide here: https://youtu.be/rDNRqASadhE
