Some people believe that accurate results require tedious measurement. But this procedure demonstrates how easy it is to get great results without squinting at a tape measure. In fact, once you've made the jigs for setting and marking the boxes, you can put your measuring equipment back into your toolbox.
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.
