ABSTRACT:
A shield is disclosed which protects the bottom of liquid filled tanks in general and underground flammable liquid storage tanks in particular. The shield is slidably secured near the bottom of the fill drop tube which is positioned within the tank. The shield bottomly covers the drop tube in a manner to protect the tank construction during stick gauging. When a gauge stick is dropped into the tank through the fill opening to measure the quantity of liquid contained therewithin, the gauge stick strikes the shield and not the bottom of the tank.
