These sturdy receptacles offer excellent value. They deliver rugged, lasting construction that hold up in a high-use commercial environment, while still maintaining the look of a traditional outlet. They are also ideal in residential applications where the outlets are regularly being used, such as the hallway for the vacuum or in the kitchen for hand held appliances. The tamper-resistant dual mechanical shutter system also helps prevent insertion of foreign objects. All 20 amp straight blade outlets will accept both 15 amp and 20 amp straight bladed plugs.
