Hello Jay, If you're referring to the VPI Type Threaded Clamp, the 2 models (actually 3 if you count the least expensive Jr version Clamp) that VPI make, are two piece, but conjoined, so that when you tighten the Clamp to LP, the bottom portion remains motionless against the Label, thus never causing any marring of the Label, at least none that I ever noticed, or had a problem with.
And as you might know, VPI as well makes a Heavyweight Clamp, which I assume is not threaded.
There's of course other companies, one new one that I've recently noticed, called ttweights.com. Thier VPI Style Clamps appear to me, to be one solid piece of metal, and I can imagine, that yes, while Clamping a one solid piece Clamp down upon the LP, that there's that possibility of Label marring. Only ttweight's Collet Style Clamp appears to be a two piece affair.
TTweights.com also appear to make a number of Clamps/Weights with no threads, probably somewhat similar to the VPI Heavyweight, but possibly not quite as dished on it's underside? They look very nice, and are not really that expensive. Hope this helps. Mark
