  • Door threshold shield apparatus
    Patent number: 8857107
    Abstract: A door threshold shield apparatus includes a shield body shaped for covering a portion of a door threshold. The shield body can include a sheet metal or other suitable material. A hook is positioned on a first longitudinal edge of the shield body for retaining the shield body on a first edge of the threshold, and a cap flange is positioned on a second longitudinal edge of the shield body. The cap flange is shaped to be received between a removable cap flange on the threshold and a threshold base, thereby rigidly securing the shield apparatus to the threshold. Once construction is complete, the shield may be removed without removing the threshold base by detaching the threshold cap.
