Bessey LM2.004 LM General Purpose Clamp
MightyMini is a handy little guy that does the work of a 1-, 2- or 3-inch c-clamp - but nine times faster. Built to lighter specs, it can handle the majority of lighter duty clamping tasks.  This clamp features quality cast jaws with a bright drawn steel rail serrated on two sides, an ergonomic grip wood handle, and a protective non-marring cap. There's a 2-inch nominal throat depth with a 4-inch nominal opening.
