3990 Tower jaws for the Stronghold

Tower jaws like this one (3990) are made to clamp long work such as a vase, for example. The 3990 is the largest size tower jaws for the Stronghold chuck with ribbed insides. These ridges squeeze into the wood and provide a firm grip. At the end of the jaws, the steel on the inside extends into a dovetail so you can also use it for a shorter workpiece, this again saves changing jaws.
