Find more than 1,300 steel electrical boxes, covers and accessories, mostly from Southwire's Topaz line plus Westgate. You'll find 4-inch and 4-11/16-inch square boxes, octagon and handy boxes, drawn and welded boxes, multi-gang switch boxes and extension rings, masonry boxes, device rings, raised and industrial covers, blank covers and BX/MC connectors.
How do I choose the right steel box? Size the box for the number of conductors and devices it will hold, then pick the depth and knockout sizes (1/2-inch, 3/4-inch or both). Choose the mounting style, such as bracket-mounted or masonry. Raised device rings and covers bring the box flush with the finished wall. Topaz and Southwire items are final sale under our returns policy. Orders of $500 or more ship free within the contiguous US.
