The box-setting jig enables you to quickly position outlets at a uniform height and with a consistent projection from the framing. You then use the marking jig to transfer the position of each box to the floor, virtually guaranteeing that you’ll never bury a box behind the drywall. The marking jig then enables you to lay out the box’s outline onto the face of the panel. Cutting the opening with your jab saw is a quick and confident process. Allow approximately 5 minutes per outlet box for setting, marking, and cutting. Before you begin, install wiring and have it inspected, if required by local regulations. First, run the wiring to the stud bay, and coil an extra length of wire to make it easy to grab later. For safety, cap each conductor of the wire with a separate wire nut or tape. After you attach the drywall, cut a hole for the box. You can trace the outline of the box onto the wall or get a free paper template from the store where you buy the electrical box. Pull the wires through the hole, thread them into the box, and set the box into its opening. Rotating the mounting screws of the box turns ears that press against the back surface of the drywall to securely hold the box.
