Same basic function as the 303 Standard Head (above),
 except that the stem is cast into the back of the head. This
 allows the head to be positioned more closely to the work
 surface (great for use under a magnifying light).
 When used with a 305 Low-Profile Base (see page
 13), you can create a very low-profile vise.
 Features steel jaws. Nylon, grooved nylon, brass,
 and Teflon® jaws are available as accessories for
 this head (see page 22).
 Length: 7.75” (196.8 mm).
 Weight: 1.4 lbs. (0.6 kg).
