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 Electrical Box with Convenient Adjustability

Would Recommend

This is a well-designed electrical box that offers a practical solution for both new installations and remodeling projects. The adjustable design is especially useful because it allows you to position the box properly for a clean, flush finish. The polycarbonate construction feels sturdy, and the design makes installation straightforward. A great option for anyone doing electrical work or home renovations. I would definitely recommend it!

Are you going to make these boxes with less depth? On an exterior wall there won’t be any insulation between the box and wall, one a little shallower would be nice.
