Sigma Engineered Solutions 16801 Non-Metallic Weatherproof Outdoor Outlet Kit – Lockable IN-USE 15A GFCI

Overview

Elevate outdoor power safety with the Sigma Engineered Solutions 16801 weatherproof outdoor outlet kit. Built around a durable, non-metallic design and a deep 3-1/8" cover, this complete kit keeps in-use outlets protected in wet and damp settings, whether you’re grilling on the patio, tending a garden, or powering seasonal equipment.

Designed for accessibility and reliability, the kit centers around a Tamper Resistant, Weather Resistant (TRWR) GFCI receptacle housed inside a gasketed, weatherproof enclosure. This configuration minimizes exposure to moisture while keeping essential power readily available for outdoor lighting, tools, and devices. While individual results vary with usage, the setup can help maintain operation in challenging outdoor conditions.

Flexible installation and security

The patented corner hinge lets you mount the cover in either vertical or horizontal orientations, so you can fit the space and style of your outdoor area. The 3-1/8" deep cover design keeps the GFCI receptacle protected while still allowing convenient access when needed. A locking tab at the bottom provides an extra layer of cord management and helps deter unauthorized access, contributing to safer, more organized outdoor power use.

Quality and compliance

Built for outdoor performance, this kit is cULus listed and NEMA 3R rated, meeting NEC’s Extra Duty standards for demanding environments. While outcomes depend on installation and usage, the kit is designed to deliver durable, long-term protection for wet locations such as porches, decks, and outdoor workshops.

Picture string lights setting the mood for a summer evening, a power tool feeding a weekend project, or a fountain feature receiving steady supply—all while the outlet is secured behind a weatherproof cover.
