The optional Shark Jaws feature a serrated surface that gives a strong grip on the workpiece that will not let go. The top 1/4" of the jaws can be used for contracting on a dovetail spigot or expanding into a dovetail recess. The jaws are 1-3/8" deep.
Grips: 1-7/8" to 3-1/4" Expands: 2-5/8" to 4-1/2"
Jaws may differ slightly from picture
