Temporary vent opening cover

摘要

A temporary vent opening cover is disclosed which is securable over a vent opening in a floor or other surface during building construction to prevent debris from entering the vent opening and accumulating in duct work associated therewith. The cover includes a generally flat cover plate which is sized and shaped to cover the vent opening. The cover plate is spaced outwardly from the surface when the vent opening cover is secured over the vent opening. A plurality of air passages allow air to flow past the cover plate between the duct work and the workspace. A layer of air filter material covers the air passages and prevents debris from passing therethrough. A portion of cover plate may be dedicated to the display of promotional indicia.
