The term "outlet covers" most often refers to the plates that surround wall-mounted electrical outlets. The plates serve to cover the hole into which the outlet has been set and the wires within. They also provide a finished look to the outlet and may be either functional or decorative.
Outlet covers may be purchased in hardware, home improvement, and department stores as well as online. They frequently come in a set size and shape, often a rectangle, based on the standard use in the geographic location in which they are being sold and usually accommodate one, two or four outlets. Most are plastic, though metal plates may be used, particularly in industrial applications. They are usually available in standard colors, such as white, beige and black.
Typically, basic outlet covers are relatively inexpensive. The most inexpensive version is normally sold at a slight discount in a bulk pack of several units. These are often called contractor packs because they are commonly purchased by contractors who are building a house or commercial building requiring many covers. Most stores also sell the them individually for homeowners or contractors who only need to replace one or two.
Decorative outlet covers are available in a wide range of designs and materials. They may be brushed aluminum, brushed copper, stainless steel or virtually any variety of wood. They may be printed or hand-painted in any number of designs, ranging from cartoon characters to classic floral motifs to modern art designs. They also may be covered in fabrics, from silk to burlap.
While the hole shapes will still conform to fit standard outlets, the overall shape of decorative covers may be square, rectangular, round or free form. Decorative covers may be available in some home improvement and department stores, but the selection is usually more extensive at online vendors. Interior design and home decor stores may also sell decorative varieties.
Installing an outlet cover is a simple task. The plate simply affixes to the wall with a single screw, which is generally included in the package. The screw is usually tiny and can be tightened with just a few twists of a manual screwdriver or, in a pinch, a butter knife. Those concerned that they may slip and insert the tool into one of the outlet holes should shut off power to the outlet at the breaker box before beginning.
Plastic plugs or inserts that are placed into the receptors of outlets when not in use are sometimes described as outlet covers as well. These plugs are intended to prevent small children from accidentally shocking themselves by inserting fingers or other objects into the outlet. They are available at many hardware and home improvement stores, in baby stores, in many department stores, and online.
