Mole grips is another term for locking pliers. They work in exactly the same way as locking pliers. All pliers us a simple lever and fulcrum system to exhibit force on an object to either keep it in place or move it in the desired direction. Locking pliers use the same basic system but have additional features that keep them securely attached to the object. To use them safely and effectively, first, open the jaws using the quick release lever. Then place the jaws around the object you want to grip. Close the handles together until the jaws close around the object. Use the adjustment screw to get the best possible grip. Complete your task and then use the quick release lever to safely remove the mole grips from the object.
