A waste line trap is provided to prevent foreign objects and debris from being flushed through commodes into waste line systems. The waste line trap has a solid cylinder with continuous outer and inner walls. A plurality of angled fins are spaced equidistantly on the inner wall and extend outwardly toward the center of the cylinder. The fins have downwardly extending top beveled edges which terminate in vertically extending inner beveled side edges. The trap is installed in the discharge line of a commode and functions to catch foreign objects and debris from entering the main sewerage line.
