ABSTRACT:
Disclosed is a device for accurately cutting away a section of a panel opposite an electrical outlet box. This device employs a locator plate having two sets of pins, each set extending outwardly from opposite sides of the plate. With the locator plate in position, the panel is placed over the plate with one set of pins piercing the panel. The template is then placed in position with holes in the template servicing to guide the pins piercing the panel and bring the template into registration with the open side of the box so that the center of the template coincides with the center of the open side. With the template in position, the marginal edges of the template overlap the edges of the open side. The user can now use a cutting tool to cut the hole tracing a path defined by the marginal edges of the template. An extension plate is provided for a double outlet electrical box.
