Great for lock work. It’s light enough to carry around, but heavy duty enough to hold key blanks, lock cylinders, or small parts. Attaches to any flt, smooth surface with its vacuum base, swivels 360 degrees, tilts 90 degrees and locks into any position. Complete with rubber jaw covers. Jaws are 2-3/4” length and open to 2-3/4” wide. VTTV.
