Copkim 4-Pack 4" Square Metal Electrical Boxes – With Covers, Ground Wires & Screws, 2-Hour Fire Rating, 11 KO's 1/2" And 6 KO's 3/4"

About This Product

If you're wiring up a workshop, finishing a basement, or doing a home renovation, you'll need some solid junction boxes to keep everything safe and code-compliant.

This Copkim 4-pack gives you four 4x4 inch metal boxes – galvanized steel, tough as nails.

Each one comes with a duplex outlet cover, a green ground wire (about 7.
87 inches long), and four screws.

So you're not hunting for hardware – it's all right there.

These boxes are designed for serious durability – they're rated for 2-hour firewalls, so they hold up in a fire and protect your wiring.

Each box has eleven 1/2-inch knockouts and six 3/4-inch knockouts – that's a ton of entry points for running conduit or cables, so you can keep everything neat and organized without cramming wires into tight spots.

Capacity is 21 cubic inches, which is roomy enough for multiple connections, switches, or receptacles.
The exposed work cover gives you extra protection against dust, moisture, or accidental contact.
Use 'em indoors or outdoors – they're versatile and built to last.

Just remember to keep the small parts away from little kids.

For the price of a 4-pack, this is a no-brainer for any serious DIY electric project.
