A pipe trap assembly is described. Embodiments of the pipe trap assembly can include a first plate, a second plate, and a plurality of fasteners. The second plate can include two or more protrusions extending inwardly from an interior edge of an opening in the second plate. The protrusions can be implemented to frictionally engage a waste line. In one example, the pipe trap assembly can be used to secure a waste line for coupling to a drain base of a drain assembly.
