2. Measure and Mark
Measure the height of the existing electrical outlets (to the bottom of the plate) and mark your safe’s location at 1/2″ higher. The extra half inch compensates for the plate, placing your new false outlet at the exact same height so it doesn’t appear conspicuous.
Measure the size of your gang box and mark that carefully on the wall. The more meticulous you are with the measuring and cutting, the better your chances of having a very inconspicuous final product.
