Leviton R77-TWR20-00W 20A Tamper Weather Resistant Outlet

Product Description

The LEVITON MFG CO R77-TWR20-00W is a commercial-grade, tamper-resistant and weather-resistant duplex receptacle rated at 20 amps. Built from durable nylon, it features an internal shutter mechanism that blocks contact access unless a 2-prong plug is fully inserted, preventing foreign objects from entering the slots. A shallow-profile body maximizes wiring room inside the box. Side-wired terminals with large-head screws and back-wiring clamps accept up to No. 10 copper wire. Triple wire power contacts deliver strong conductivity and reliable plug retention. This unit is sold as a pack of 10 and ships at 2.61 pounds.

This receptacle is suited for both indoor and outdoor installations where tamper resistance and weather resistance are required by code. Common applications include exterior walls, garages, bathrooms, kitchens, pool surrounds, and commercial facilities where NEC Section 406.8 compliance is mandatory. Captive mounting screws speed up installation, and washer-type break-off plaster ears allow flush alignment with the wall surface. Break-off tabs enable easy conversion to 2-circuit wiring configurations. Licensed electricians typically install this device in new construction and retrofit projects alike.
