Description:
These parallel jaw pliers feature interchangeble jaws and replaceable jaw tips. There is provision for a wire cutter. The pivot pins can be removed to allow the jaws free movement. A bar with teeth extends from one handle through a slot in the other handle. This bar can engage a pin in the slot to form an adjustment lock. A small cam can be turned to hold the adjustment lock in place.
