Metal outlet box with wings

Choose the category based on mounting method, environment, and box capacity. Consider whether you’re mounting in-wall or on a surface, the space behind the wall, and how many devices you’ll install. Look for boxes with wings designed for your framing and weather conditions, and pick a gauge that matches your wiring needs. Brands like RACO, Carlon, and Arlington offer wings-equipped metal boxes in several sizes.

The wing mounting design and knockouts configuration are the most complex attributes to consider. Wings determine how the box anchors to studs and how flush or protruding the box will be in the finished wall. Knockouts must align with your conduit or cable entry and provide the right device spacing. Choose wings and knockout layouts that fit your wall thickness and wiring plan.

DIY users typically select standard, easy-to-install wings boxes that meet common codes. Professionals may require deeper, weather-rated, or specialty versions and precise knockout counts for complex installations. Consider tool compatibility and the need for secure grounding when deciding between the two.

Keep the box clean and dry to maintain ground integrity. Check that the wings stay firmly attached to framing and that mounting screws are intact. Ensure the box and cover meet local electrical standards and are suitable for the installation environment.

Size and capacity should match the number of devices and wires you plan to install. Estimate box fill and allow for future upgrades, if possible. Opt for a larger box when space permits to reduce crowding and heat buildup.
