Secure these heavy duty vises to the back of a truck to clamp at your job site. These vises mount directly to a standard 2” hitch with the included pin. Moving parts are enclosed to keep contaminants out and lubrication in for smooth operation. In addition to flat jaws, vises have V jaws (also known as pipe jaws) that securely grip pipe and other round objects. Use the anvil for bending and shaping material with a hammer. Vises include a bracket for benchtop mounting.
