ABSTRACT:
A unitary door routing template for routing hardware mounting apertures in doors is provided which affords expedient placement of the template and the cutting of hardware mounting holes while minimizing expense and hazards to operating personnel. The template comprises two elongated, planar, unobstructed, opposing sides for engaging the front and back sides of a door, the template sides being integrally formed with and extending generally perpendicular to an end plate which engages the door edge. The planar opposing sides are spaced from each other at the end plate by a distance equal to or slightly greater than the thickness of the door and, preferably, gradually converge away from the end plate so that, when placed over the door, they provide a stabilizing grip on the door surfaces. The entire template, and particularly the template in the vicinity of the router guide holes, is preferably formed of flexible friable material, such as plastic, and has a thickness greater than 1/4 inch to prevent disintegration of carbide router bits in use due to kick-back and contact of the bit with the template.
