Hold workpieces steady with these vise jaws—they work with slot-mount workstops so you can quickly position, adjust, and change out your workpieces. Using jaws and workstops together keeps the workpiece from slipping, and gives you more control over the position than jaws alone. Slide your workstop into a slot on either the top or the bottom jaw and tighten with a screw. One slot is closer to the jaw face than the other to give you more positioning options. These jaws have industry-standard mounting hole patterns to match most vises, including those made by Kurt, Chick, TE-CO, Toolex, and Palmgren.
