A door hardware tool includes an edge wall with a first side, a second side opposite the first side, and an edge bore aperture that extends through the first side and the second side. The edge bore defines a first axis that extends centrally through the edge bore and through the first side and the second side. The door hardware tool also includes a side wall coupled to the edge wall. The sidewall includes a first side, a second side opposite the first side, a cavity defined between the first and second side, and a cross bore aperture moveable between a first setback position and a second setback position within the cavity along a second axis. The second axis is parallel and offset from the first axis.

The template for a router to notch a door latch slot is a jig that is adapted for use in routing slots in door slab such that the door slab can receive a latch. The template for a router to notch a door latch slot is clamped to the door slab such that an aperture formed in the template for a router to notch a door latch slot is positioned over the lock rail of the door slab. The aperture can then be used as a template for the router to create a door latch slot to receive the latch plate of the door lock. The template for a router to notch a door latch slot comprises a U channel, a pressure plate, and a thumbscrew.

A jig assembly for marking a cabinet with hole positions that are needed to install hardware. The jig assembly utilizes a reference plate. At least one matrix of holes is formed through the reference plate. The holes are used to make markings at different positions and distances. The holes are preferably identified with scale indicia that provide visual indications as to the positions of each of the holes. Arms are attached to the reference plate with pivot connections. Marking holes are disposed through the arms. The arms can rotate and extend from the reference plate in opposite directions. A top plate is positioned across the top edge of the reference plate. The top plate creates a guide. A side plate is positioned across a side edge of the reference plate. The side plate creates a second guide that intersects the top plate at a perpendicular.

A jig for positioning door jambs has a base template and an alignment rail each part including opposing notch patterns and locator pin patterns, the alignment rail assembled to the base template and adjustable to travel via slots in the base template to enable stacking a pair of door jambs in correct configuration inside a constructed doorway for installation to the constructed doorway frame members.

An adjustable arch measuring tool measures an arcuate curvature of one of a window and a door and thereby assists a user to layout a radius of the arcuate curvature on an existing cutting surface. The adjustable arch measuring tool includes a first member having an arcuate slot defining an adjustable fulcrum axis formed at a proximal end thereof, a second member having an aperture formed at a proximal end thereof, and a fastener removably inserted through the aperture and selectively locked along a curvilinear longitudinal length of the arcuate slot. Advantageously, the second member is selectively pivoted about the adjustable fulcrum axis defined along the arcuate slot of the first member. With the use of reference points and guide pins, each half of the arch can be easily drawn directly on the working surface.
