Outdoor Outlet Box Waterproof with Dual 20 AMP GFCI Receptacles

Our review looks at a practical, no-nonsense outdoor power solution aimed at homeowners and installers who need a waterproof receptacle with built-in safety. The SURAIELEC outdoor outlet box combines dual 120Vac, 20 AMP WR & TR GFCI receptacles with a 3R-rated all-metal enclosure, and the biggest reason to buy is its blend of weather resistance and integrated ground-fault protection for outdoor lighting, holiday decorations, or temporary power needs. It is best for anyone wanting a rugged, lockable outdoor outlet that is straightforward to install and maintain.

Key Features

• Built-in GFCI protection: Dual 120Vac, 20 AMP WR & TR GFCI receptacles interrupt power on a ground fault to protect users and equipment outdoors.
• Weatherproof metal enclosure: The 3R-rated galvanized steel box is rainproof, dust-tight and rust-resistant for long life in exposed locations.
• Pre-punched knockouts: Knockouts on the sides, bottom and back in three sizes make conduit or cable entry quick without drilling.
• Lockable cover: A metal, lockable design helps secure the receptacles for public or seasonal use at campsites, porches, or event spaces.
• Complete kit: The package includes the steel box, gasket, metal cover and dual GFCI outlets to provide an economical, ready-to-install outdoor power point.

Who It's For

The product is well suited for DIY homeowners, landscapers and contractors who need a durable outdoor receptacle for lights, holiday decorations, or temporary equipment. Its all-metal construction and lockable cover make it appropriate where security and weather resistance matter, such as porches, yards, campgrounds or small public charging points.

Those who require advanced integration with smart home systems, specialty outlet types, or commercial grade specifications beyond a 3R rating should consider other options. Also, buyers who need guaranteed flawless GFCI operation in every unit should note that some users have reported mixed functionality with the GFCI modules.
