A junction box that won't hold the knockout or doesn't accommodate the wire bundle makes for an installation nightmare. This 4-11/16" steel junction box with 12 knockouts handles the capacity of a full commercial run — multiple 1/2" and 3/4" KOs on every side, walls rated to code depth. The 4-11/16" square gives you the cubic inches you need for 12-gauge wire bends and future capacity. Gauge steel that doesn't flex when you nail it off. Standard in commercial build-outs for electricians across northeast Nebraska and northwest Iowa. In stock at Crofton Lumber (Crofton, NE) and Akron Lumber (Akron, IA) — ready for pickup today.
