Abstract: The present invention is a masking system or kit which protects door and room hardware from contamination during the painting and other similar processes. These are a variety of mask described, each of which protects a different piece of hardware, such as door hinges, door knobs, dead bolts, and wall electrical outlets and switches. The masks work in combination to protect all of these items, but may be used individually. The masks of the present invention are reusable, but are cheap enough to manufacture that they may be disposable. A unique feature of many of the mask embodiments of the present invention is a tapered cross section which creates a fine edge which closely fits into the join between the hardware and the door or wall.
