Can you tell me if this is the speed ring I need for Westcott's 7' Octobank soft box?
Hi. For alienbees, Einsteins, etc...yes it is. For the 7' Westcott Octa, I would be sure to use the mounting bracket that comes with the octa to place it on a c-stand, etc. Otherwise the full weight is on the strobe....which cannot adequately support the octa.
