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. ## Claims ### Claim 1 A pipe end protector, comprising: 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 having a peripheral edge having a first portion connected to the protector body by a hinge and a second portion initially connected to the body by frangible webbing, the knock-out being deflectable from the protector body about the hinge; wherein, when the protector is attached to the pipe end, the frangible webbing can be broken away from attachment with the body and the at least one knock-out remains attached to the protector body while hingedly deflecting from the protector body about the hinge. ### Claim 2 (depends on 1) The pipe end protector according to claim 1, wherein the at least one knock-out is returnable to an original position with respect to the protector body. ### Claim 3 (depends on 1) The pipe end protector according to claim 1, wherein the protector body is generally cylindrical in shape. ### Claim 4 (depends on 1) The pipe end protector according to claim 1, further comprising a threaded portion capable of engaging threads on the pipe end. ### Claim 5 (depends on 1) The pipe end protector according to claim 1, further comprising at least one grooved portion formed on an outer surface and substantially parallel to a longitudinal axis of the protector body. ### Claim 6 (depends on 1) The pipe end protector according to claim 1, wherein a plurality of notches are formed in the protector body for accommodating a torque-applying device. ### Claim 7 (depends on 1) The pipe end protector according to claim 1, wherein the hinge is a living hinge. ### Claim 8 (depends on 1) The pipe end protector according to claim 1, wherein the protector body and the at least one knock-out are integrally formed of molded polymeric material. ### Claim 9 (depends on 1) The pipe end protector according to claim 1, wherein at least one vent hole is formed in a wall of the protector body adjacent the at least one knock-out. ### Claim 10 (depends on 1) The pipe end protector according to claim 1, wherein the protector body and the at least one knock-out are formed as one piece. ### Claim 11 A pipe end protector for protecting a pipe end from damage and for preventing moisture and other contaminants from entering a pipe through the pipe end, comprising: a body; an end wall connected to the body and positionable adjacent the pipe end; a plurality of knock-outs formed in the end wall, each knock-out being movable between a closed position parallel to the end wall and at least one open position different from the closed position while the end wall is positioned adjacent the pipe end, the at least one open position being a position in which each knock-out hinges inward toward an interior portion of the pipe; and means for maintaining connection between each knock-out and the end wall in said open and closed positions. ### Claim 12 (depends on 11) The pipe end protector according to claim 11, further comprising thread-engaging means for engaging a threaded portion of the pipe end. ### Claim 13 (depends on 11) The pipe end protector according to claim 11, further comprising engaging means for engaging a torque-applying device. ### Claim 14 (depends on 11) The pipe end protector according to claim 11, further comprising grip-enhancing means to enhance manual gripping of the pipe end protector. ### Claim 15 A protector for protecting a pipe end, comprising: a body engageable with a pipe end; an end wall connected to the body, the end wall having a shape substantially matching a shape of a pipe end; and access means formed entirely within a central portion of the end wall and attached to the end wall by a living hinge, the access means selectively permitting access to an interior portion of the pipe end through the end wall while the body engages the pipe end. ### Claim 16 (depends on 15) The pipe end protector according to claim 15, wherein the selective access-permitting means comprises a knock-out. ### Claim 17 A method for protecting and manipulating a pipe end, the method comprising: covering a pipe end with a protective body; providing at least one knock-out portion in the protective body, the at least one knock-out portion being movable between a closed position and at least one open position being a position in which the knock-out hinges inward toward an interior portion of the pipe end; deflecting the knock-out portion from the closed position to the at least one open position, thereby forming an opening in the protective body while maintaining attachment between the at least one knock-out portion and the protective body; and inserting a pipe-manipulating device into the pipe end through the opening to move the pipe end to a desired location. ### Claim 18 (depends on 17) The method for protecting and manipulating a pipe end according to claim 17, further comprising: removing the pipe-manipulating device from the opening; closing the opening by deflecting the at least one knock-out portion from the open position to the closed position.
