Leviton 16P21-UE Nema 3R Single Pole Protective Cap

Product Description

The LEVITON 16P21-UE is a male single pole protective cap rated NEMA 3R for use with female plugs in electrical installations. This cap provides a weatherproof cover that shields exposed female plug contacts from moisture, dust, and debris when the plug is not in use. Rated NEMA 3R, it is designed to handle rain and sleet exposure, making it suitable for outdoor and semi-protected indoor applications. The black color finish blends with standard wiring devices. Licensed electricians and electrical contractors install this cap as part of a safe cord and plug management practice on job sites and permanent installations. It meets CSA and UL listing requirements.

The 16P21-UE is used in residential and light commercial electrical applications where a female plug must be capped and protected from environmental exposure when disconnected. Typical install scenarios include outdoor receptacle cords, portable power equipment, temporary power setups, and any single pole plug assembly requiring a rated protective cover. The NEMA 3R rating makes it appropriate for use in locations subject to rain or outdoor weather without full submersion risk.
