What Customers Are Saying

Customers overwhelmingly praise this electrical box for its reliability and ease of installation, particularly for old-work remodels in homes without existing boxes. Most highlight how simple and fast installation is, noting it requires no studs and fits securely in drywall with a helpful template. Many commend its suitability for retrofitting older homes and replacing outdated boxes. However, several reviewers consistently report issues with included screws that strip easily and wing tabs that break during tightening, prompting some to use their own hardware. Despite these hardware concerns, most customers find the box functional and worth purchasing again.

Garage lighting

Would Recommend

Bought these to use in the garage. Previous owner did a half rigged job with wires hanging out of a small hole in the ceiling and crappy lights barely attached. Used these to redo the lights and a properly tie wiring up.

Found a light hanging from the ceiling!

Would Recommend

Some how when the contractors installed a light they managed to break the existing box, after 12 years the broken box gave out and I happen to look up and saw the light fixture hanging by the wire! So replaced it with a new one, easy to install, the tool you need is a screw driver!
