You're running a new circuit in a basement finish or garage and your switch box is too shallow - the device sits proud of the drywall and the inspector flags it. A 1-gang steel box with adequate depth solves the fit problem before it becomes a callback. 1-gang capacity fits a single switch, receptacle, or device. 1-inch depth handles the most common residential device depths without being oversized for the cavity. Steel construction with cable clamps means Romex stays put without separate staples inside the box. Pre-formed nail slots speed the mount to wood studs. Multiple knockouts for NM cable entry in standard configurations. Standard in the rough-in inventory of electricians and remodelers across northeast Nebraska and northwest Iowa - the switch box that fits when the depth is tight. Stocked at Crofton Lumber and Akron Lumber.
