The Speed Ring for OCF Flash Heads from Profoto is part of the Off-Camera Flash system developed for the B2 head but is also compatible with the B1 and B10 Off-Camera Flash. The speed ring has been scaled down and fitted with an easy patent-pending snap-in system for the softbox rods while the hard rubber collar has been replaced with a lighter weight silicone rubber substitute. The speed ring and optional softbox are able to rotate 360 degrees.
