I’m quickly running out of clamps (that I own), however, while many may refer to this as a vise, I often use it as a clamp on my mini workbench when used to assemble puzzles on my office computer table’s end.
Without repeating myself, let me point you at a review I have just posted on this “clamp”…
Nice review. I have a similar vise that I've had for a number of years. I have a few baseplates mounted in different areas as it slides free with the flip of a lever. Works well for some things. Claims to have up to 500 lbs of holding pressure and has quick release.
