Abstract: A protective hole cover having a plurality of slots along which slide friction locks secured by screws. Since the slots extend radially outward, the protective hole cover may be releasably secured to holes of varying dimensions. To secure the hole cover, two of the friction locks are positioned at an appropriate distance from the center of the protective hole cover and secured by the screws extending through the slots and into the friction locks. The protective hole cover is then placed within a hole with the two friction locks contacting an interior surface of the hole. The third friction lock is then slid outward to engage the interior surface of the hole as well and the friction lock is thereafter tightened to secure the protective hole cover over the hole. When it is desired to remove the protective hole cover, one of the screws 40 is loosened and the friction lock slid inward toward the center of the protective hole cover.
