A pipe end protector includes a protector body having a shape substantially matching that of a pipe end and at least one knock-out formed integrally with the protector body. The at least one knock-out has a peripheral edge having a first portion connected to the protector body by a hinge and is deflectable from the protector body. The at least one knock-out remains attached to the protector body while hingedly deflecting from the protector body about the hinge.
