This vise can be bolted to your work surface, clamped in the jaws of your woodworking vise, or secured with an optional bolt assembly through a 3/4" diameter bench dog hole. The arched base allows work to overhang the edge of your bench, so the piece can be worked by hand or power carving tools without obstruction.
The 3-1/2" diameter mounting plate, with three screw slots, is attached to a 1/2" steel rod with 3" height adjustment capability. Spare faceplate and mounting rods let you quickly changeout workpieces.
It's a handsome design, an excellent value, and works better than any other model we've seen.
