What is the diameter of the lip side that goes into the softbox? Please go measure it ;)
The rubber ring of the SMDV Mount Adapter for Profoto Flash Heads (B&H# SMPROFOTOAD) is designed to be large enough for it to slip onto Profoto strobe heads such as the Profoto B1, B1X, B10, B10 Plus, B10X, B10X Plus, and so on. Rather than relying on a constant size, articulating the lever on the side of this adapter effectively constricts the opening of the rubber side of the ring so that it grips the front of those strobes securely. To be clear, the ring is not a constant size but rather becomes tighter (i.e. more constricted) when one flips the side lever. Given that it's made of rubber and not molded plastic, you should expect some variance both in its inner diameter and also at different ambient temperatures. However, it will work with the aforementioned strobes and also with any other strobe that can utilize the same speed rings and inserts as those.
