Its not all thread, it is a patented fast thread, move to the left approx 1/2 turn unlocks, then you can lift or lower the handle without screwing up or down and slowing your work process down, then about a 1/2 turn to the right when tightening locks the thread, then you can tighten as needed. The pad ends are also removable , change from the v end to the flat for bigger pipe. Most I have seen are made with a threaded shaft that walks off the pipe, are a small diameter and bend, or they put a makeshift union on them to get the end to swivel,then when the clamp thread is raised it actually tightens as it goes up, etc etc,
As for our clamps,they work, been using mine for years, service parts are avail if needed, dont have to lose a weekend building and mocking up clamps with standard thread counts and non swivel ends.
Got a new batch of clamps forsale, I edited my first listing / post, if interested click on the link on the first post, lowered the price on these clamps to stir things up a bit.
