ABSTRACT:
Tri-spacer for centering and holding drop pipe and electric wires in the center of a well casing. The tri-spacer consists of a one-piece triangular member with flexible ends providing a centering action with very little constriction, binding, or drag on the well casing when the drop pipe and electric wires are lowered or raised in the well, and at the same time keeping the drop pipe and electric wires centered. The tri-spacer includes an insert wedge for locking action to the well casing and a sharp annular ridge on the inner diameter of the tri-spacer making an impression in the drop pipe.
