What Customers Are Saying

Customers overwhelmingly praise these electrical boxes for reliable performance in retrofit and new installations. Most highlight easy, intuitive installation with angled screws that bite securely into studs, eliminating weak drywall flanges. Reviewers consistently note sturdy, thick plastic construction that feels rugged and stable compared to flimsy alternatives, with secure mounting ideal for heavier devices. Many appreciate versatility for both old-work retrofits and new construction, plus ample internal space for GFCIs in confined areas. A few mention difficult-to-drive screws or awkward cable clamps, but overall satisfaction remains exceptionally high.

Great size, easy to use.

Would Recommend

Perfect for our project but the included screws are pretty cheap so we used better ones. Screws get a bit deep in the box, so an extension might help when using a cordless driver.

Decent box

Would Recommend

I like that these boxes don't require a Romex connector. These types of boxes are good for dimmers, because they don't have a flange that causes the plate to stick out. However I think it's dumb how they have different inlets rated for different size wire. They should design them so they're all good for up to 10/2 cable.

Easy to install. Durable.

Would Recommend

The angle installation makes it easier to install versus straight screw installations. The fit for the Smart box made it easy to slide through the drywall.

Great post construction electric box

Would Recommend

This is a highly recommended electric box, that is perfect when the walls are already sheetrocked. I had to add an outlet, and it was a great solution. It’s sturdy and has the same results and strength as if it was installed before being sheetrocked. The screws are angled perfectly to go right into the stud, and their is plenty of room in the box.
