A cutting guide apparatus for guiding placement of bore holes in a door may include an engagement interface and a backset assembly. The engagement interface may be configured to retain the apparatus proximate to an edge of a door. The engagement interface may include a handle hole guide structure and an edge bore guide structure. The backset assembly may be operably coupled to the engagement interface to enable an amount of backset from the edge of the door to a center of the handle hole guide structure to be adjusted. The engagement interface may include a first leg configured to be disposed along a first face of the door, and a second leg configured to be disposed along a second face of the door. The backset assembly may be configured to engage the edge of the door at a variable location between the first and second legs.

A cutting guide apparatus for guiding placement of bore holes in a door may include an engagement interface and a backset assembly. The engagement interface is configured to retain the apparatus proximate to an edge of a door and center an edge bore guide between an inside face and an outside face of the door. The engagement interface includes a first arm and a second arm that are each operably coupled to a common pivot axis. The backset assembly is operably coupled to the engagement interface to enable an amount of backset from the edge of the door to a center of a handle hole guide to be adjusted. The backset assembly includes a first mounting bracket operably coupled to a first portion of the first arm and a first portion of the second arm, and a second mounting bracket operably coupled to a second portion of the first arm.

A cutting guide apparatus for guiding placement of bore holes in a door may include a first leg configured to be disposed along a first face of the door, a second leg configured to be disposed along a second face of the door opposite the first face, and a spacing element disposed between the first and second legs. At least one of the first leg or the second leg may include a handle hole guide structure and the spacing element may include an edge bore guide structure. A first portion of the handle hole guide structure that is proximate to the first or second face of the door may be undercut relative to a second portion of the handle hole guide structure that is opposite the first portion.

A drill bit jig includes an elongate member, two jig securing elements and a drill bit guide. The elongate member is hollow so that one or more elongate drill bits may be stored therein. The drill bit guide includes a plurality of through holes where the axes of the through holes are parallel to the axis of the elongate member. Each of the plurality of through holes in the drill bit guide has a different diameter for accommodating drill bits of different thicknesses. The jig securing elements each include an L-shaped bolt and a door protecting material encasing one of the straight sections of the bolt.

A jig assembly structured to facilitate attachment of a device to a door including a base having oppositely disposed first and second end segments and an open interior, including first and second open faces. The open interior and the open faces are disposed between the end segments and are cooperatively structured therewith to receive a portion of the door in an operative position therein. A clamp member is movably connected to the first end segment and is least partially disposable into said open interior in clamping relation to the door portion, when in the operative portion. The second end segment is disposed and structured to receive passage therethrough of a tool, from an exterior to and interior of the base, into engaging relation with the door portion disposed in the operative position and into an interior channel of the clamp member.

In an exemplary embodiment, a template for locating and drilling one or more holes in a door is provided. The template may include a body member having a first side portion, a second side portion, and a middle portion. The middle portion can be between the first side portion and the second side portion forming a profile that is configured to cooperatively engage with a portion of the door. The profile can include at least one curved portion to correspond to a curved portion of the portion of the door.

A boring and routing template jig for door hardware installation has a side template plate, clamping for holding the side template plate against a side area of a door to be cut and a face template plate orthogonally connected against an edge of the side template plate by a connection so that the face template plate can lie across an edge face area of the door to be cut adjacent the side area. The face template plate and the side template plate comprise respective guide apertures. The connection is configured to maintain vertical offset between the respective guide apertures and allow horizontal offset adjustment between the face template plate and the side template plate.
