ABSTRACT:
A guard device for use with a drop pipe in a well casing includes a pair of similar guard sections each being formed of a plastic material. Each section includes inner and outer arcuate members interconnected by ribs and plates. The inner arcuate member of each section engages the drop pipe and the outer arcuate member has tabs which engage the well casing to enter the drop pipe. A locking member on each section interlocks with a lock engaging member on the other section. Vertical passages through the sections accommodate electrical conductors, safety ropes and similar components to thereby minimize damage to these components.
