Flemoon Outdoor Extension Cord Safety Cover — 6 Pack

Flemoon Outdoor Extension Cord Safety Covers are compact, weatherproof enclosures that seal and secure plug and cord connections to protect outdoor outlets and decorations from water, dirt, and damage.

This 6-pack of black Flemoon electrical connection boxes is built for seasonal lighting, holiday inflatables, landscape equipment, and any exposed outdoor cord splice that needs a reliable seal. The boxes are made from reinforced polypropylene and include rubber gaskets, snap-lock lids, corner clips, and cable clamps to keep connections from shaking loose while blocking rain, snow, and dust. They’re UL- and CSA-standard compliant and sized for common extension cords (14/16/18 gauge) and many flat or braided cables.

How does the Flemoon box keep outdoor plugs dry and secure?

The enclosure uses multiple layers of protection: a snap-lock lid with four corner clips plus molded rubber gaskets at each cable entry to prevent water intrusion. Cable clamps hold cords steady so the connection won’t wiggle apart under tension or wind.

• Snap-lock lid with four corner clips for a tight mechanical seal
• Rubber gaskets lining each entry port to block water and dust
• Cable clamps fasten cords to prevent accidental disconnection
• Reinforced PP shell resists impact, UV, and outdoor wear

What cord sizes and plugs fit inside the enclosure?

The ports are sized for typical extension cords and decorative light cables; the entry diameter is 10 mm, which works well with 14, 16, and 18 gauge round cords plus many flat and braided wires. Larger power strips, bulky right-angle plugs, or oversized adapters will not fit.

• Entry port diameter: 10 mm — fits most 14/16/18 gauge cords
• Outer box dimensions: 2.3" x 2.3" x 7.1"; inner usable space: 2.0" x 2.0" x 5.3"
• Not compatible with power strips, large adapters, or right-angle plugs
• Good for flat wire, braided cords, and standard round extension cords

How easy is it to install and use the Flemoon connection box?

Installation is straightforward: place the plug and connected cord pair inside the box, align the cord through the grommeted entries, fasten the cable clamps, and snap the lid closed. The package includes cable ties that thread through side mounting holes for hanging or fastening to a structure.

• Simple—no tools required for basic assembly and sealing
• Four corner clips snap shut for a secure latch
• Included cable ties allow hanging from eaves or mounting to posts
• Compact and lightweight for temporary or seasonal use

Where is this enclosure most useful?

Use the Flemoon box wherever outdoor electrical connections are exposed: holiday lights, inflatables, garden pumps, landscape lighting transformers, or patio heaters. Its small footprint makes it ideal for hanging connections rather than sitting on the ground.

• Holiday lighting, Christmas inflatables, and seasonal décor
• Garden tools, pool pumps, fish pond equipment, and fountains
• Security cameras, outdoor heaters, and small appliances on patios
• Temporary job sites or events where cords hang in the air

Who is this for? Flemoon’s 6-pack of waterproof electrical connection boxes is designed for homeowners, decorators, landscapers, and event installers who need an affordable, compact way to weatherproof plug-and-cord junctions. If you use standard extension cords or decorative lighting outdoors and want to reduce the risk of water, dirt, and strain-related failures, these enclosures offer a quick, certified, and reusable solution.
