DIYers and electricians, this complete outlet box kit has everything you need for a professional-grade electrical installation in one convenient package. You get two 20 amp tamper-resistant outlets that feature those safety shutters to prevent kids from inserting objects - such a important safety feature for homes with curious little ones. The 4x4 inch metal electrical box is seriously sturdy with sixteen knockouts (ten 1/2 inch and six 3/4 inch) giving you tons of flexibility for wiring configurations. The 21 cubic inch capacity provides plenty of room for all your connections without cramming everything in tightly. The commercial-grade outlets feel substantial and durable, with self-grounding design and full saddle yokes that make wiring straightforward and secure. The included raised cover gives everything a clean, finished look that meets electrical code requirements. Whether you're adding new outlets in your garage, workshop, or tackling a renovation project, having all the components matched and included saves you multiple trips to the hardware store. The tamper-resistant feature is becoming code requirement in more areas, so installing these now keeps you compliant and safe. The quality construction means these outlets will handle years of use without loosening or wearing out like cheaper alternatives. Seriously, if you're planning any electrical work that needs reliable, safe outlets, this kit delivers professional results without the professional price tag. It's one of those projects that seems intimidating but is actually very manageable with the right components all together in one package.
