Abstract

The invention provides a method of locating a position of an electrical fixture behind a panel by using an aperture cutting guide comprising a support plate and a guide tube having a longitudinal aperture. The support plate is formed with first holes and second holes. The selected second hole and the guide tube protruding through a cut-out of a panel are positioned at an axis of the fixture installation location. A hole cutting tool having a longitudinal rotatable element and a cutting member with cutting teeth is directed towards the cut-out. The rotatable element is movably received and guided by the tube's longitudinal aperture. An opening within the panel is cut by the cutting teeth, so that the guide tube is adapted to retain a proper orientation of the longitudinal rotatable element and to prevent the cutting teeth of the tool from drifting away from a predetermined orientation.

Dependent claims

A method of locating a position of an electrical fixture behind a panel by using an aperture cutting guide, said cutting guide comprising a support plate and a guide tube having a longitudinal aperture passing therethrough, the support plate formed as a strip of flexible material provided with multiple sets of holes extending longitudinally through a central region thereof, each said pair consists of a first or large hole and a second or small hole separated from each other, said hole sets are spaced from each other;

wherein said method comprising the following steps:
determining a location for an electrical fixture installation and arranging orientation of selected said second or small hole of the support plate corresponding to a longitudinal axis of the predetermined fixture installation location;
securing said support plate to a support structure;
positioning said guide tube within the predetermined second or small hole of the support plate corresponding to location of the longitudinal axis of the fixture installation;
installation of a panel having a cut-out over the guide tube so that the guide tube protrudes through the cut-out;
directing a hole cutting tool having a longitudinally rotatable pilot and a cutting member with circumferentially oriented cutting teeth towards the cut-out;
positioning the pilot of the hole cutting tool into the longitudinal aperture of the tube, so that upon advancement of the hole cutting tool towards the panel the pilot is movably received within and guided by said longitudinal aperture;
and
cutting an aperture within the panel by said circumferentially oriented cutting teeth, so that the guide tube is adapted to retain a proper orientation of the pilot and to prevent the cutting teeth of the tool from drifting away from a predetermined orientation.
