Support Jack is something that helps to easily lift any vehicle, preferably SUVs and other heavy vehicles, so that the mechanic can perform the operations properly underneath. This jack offers consistent support and rigidity to odd shaped workpieces. This jack is designed to prevent workpiece deflection under forces created during machining operations. This jack helps in creating the vice-like action by gripping the jack post from both sides and locking the jaws. This jack is very effective and easy to operate. This is highly serviceable in giving support to the centering sheets as well as beam bottoms.
