Hey electricians and DIY pros, this RACO electrical box is seriously heavy-duty and perfect for industrial applications where you need extra space for larger wires or devices. It's a 4-11/16 inch welded square box that's 2-1/8 inches deep, giving you plenty of room to work with - we're talking 42 cubic inches of capacity! The knockouts are super convenient: you get one 1/2 inch, four 3/4 inch, four 1 inch, plus three TKO knockouts that give you even more flexibility for different conduit sizes. The raised ground feature is awesome because it means you don't need a separate bonding jumper for circuits up to 600 volts. The Phillips/slotted screw heads make installation way faster and easier - no more searching for the right screwdriver! These boxes are UL listed too, so you know they meet all the safety standards. They come in a pack of 20, which is perfect if you're working on a bigger project or just want to stock up your workshop. The welded construction means they're super sturdy and will hold up well over time, even in tough industrial environments. Whether you're working on commercial buildings, industrial facilities, or just a serious home workshop, these boxes can handle pretty much anything you throw at them. They're that reliable workhorse that makes electrical jobs so much smoother. Definitely a must-have for any electrician's toolkit!
