发明名称 Door hole cover
摘要 A door hole cover for covering a hole in a door has two substantially flat cover plates that are secured to opposite sides of the door for covering the door hole. The first cover plate has an attachment tube extending from the center of its inner surface such that the attachment tube is positioned inside the door hole during assembly. A centering disk is placed over the attachment tube and held in place by a retainer clip. A fastener fits through a hole in the second cover plate and engages an internally threaded hole in the attachment tube to secure the first and second cover plates to the door in a position covering the door hole. The centering disk inside the door hole substantially prevents movement of the cover plates in a plane that is parallel with respect to the door. The centering plate may include three removable tabs that are left in place to cover relatively large door holes, but may be removed to cover smaller door holes.
