  1. Q What is the difference between this clamp and the regular 13MHHM clamp?... Read more
    A

    The purity clamp has an enclosed wing nut.  It's also highly polished whereas the 13MHHM is not.   You'll notice that the "A" dimension for this clamp is also slightly bigger than the standard clamp, this is because the purity clamp is truly a spherical clamp.
