This popular, small precision PanaVise has all of the traditional "tilt, turn and rotate" features of it's big brothers. More like a tool than a vise, the grooved jaws open to 2 7/8" (73mm) and are made of fiber reinforced thermal composite alloy. Jaws are controlled with a fine / course adjusting knob which permits very delicate work. Head movement is through three planes (360° rotation, 360° swivel and 210° pivot) and is controlled with a single knob. The PVjr's base is made of die cast zinc for years of continuous use, with a 4 5/16" (109.5mm) bolt circle countersunk for 1/4" (6.3mm) flathead bolts (not included). Compatible with the 300 series base mounts. This unique vise is 6 3/4" tall (171.4mm), weighs 1.25lbs (0.6kgs) and is packaged in a attractive clamshell which can be hung on a pegboard or set on a shelf.
