Abstract: A template for facilitating marking of entry holes in a surface for passage therethrough of conduit has a flat portion formed of semi-rigid material and two flat sides. The flat portion has a central opening and a plurality of markings on one side. The markings are parallel to a section of the perimeter and spaced inwardly at graduated distances therefrom. A plurality of slots are formed through the flat portion, spaced apart and parallel to one another, substantially coextensively with each corresponding one of the plurality of markings, to thereby permit a user of the template to make a mark through one of the slots to indicate an outer edge of a hole of a preselected size to be formed using the template.
