Abstract: Clamping door trays are presented including: an open channel tray; a closed channel tray slidingly engaged with the open channel tray; a clamping mechanism positioned on an underside of the clamping door tray, the clamping mechanism for drawing the open channel tray and the closed channel tray together; and a support plate located along an inside bottom surface of the closed channel tray and secured through to the open channel tray. In some embodiments, the open channel tray includes: an L-shaped channel having a closed distal end and an open proximal end; and a rim located along a portion of a top edge of the L-shaped channel, the rim proceeding from the closed distal end, along an outside edge to the open proximal end.

Abstract: Bridge adapters configured for insertion into a door stile cavity within a door stile are presented, the bridge adapter including: a planar body including, a first plate disposed along a proximal end of the planar body, where the first plate includes a first plate front edge disposed along the proximal end and a first plate back edge located along opposite ends of the first plate, where the first plate front edge includes a locking tab sized to couple with a locking indent, a second plate including a second plate front edge and a second plate back edge located along opposite ends of the second plate, where the second plate front edge is mechanically coupled along the first plate back edge by a leading hinge.

Abstract: Bridge adapters configured for insertion into a cavity within a door stile are presented, the bridge adapter including: a planar body including, a top plate disposed along a distal end of the planar body, a first side plate including a first side plate front edge and a first side plate back edge located opposite the first side plate front edge, where the first side plate is mechanically coupled along the first side plate front edge and the top plate back edge by a first hinge, a bottom plate including a bottom plate front edge and a bottom plate back edge located opposite a bottom plate front edge, where the bottom plate front edge is mechanically coupled along the first side plate back edge and the bottom plate front edge by a second hinge.

Abstract: A tool for aligning a door hinge with the edge of the door to which it is mounted comprising a bar having a wrench on each end of the bar. The faces of each jaw of the respective wench are contoured to fit around a single knuckle of the hinge. The bar has a slit arranged to permit the jaws to open or close around the surface of a knuckle of the door hinge. A screw through the bar is arranged to permit tightening the jaws onto the knuckle when it is required to apply force to the hinge or loosen the tool when it is required to slip the tool off the hinge.

Abstract: A drill guide apparatus for enabling the accurate drilling of holes in a door for the installation of a door handle assembly or lock comprises a generally U-shaped member sized to fit around the edge of a conventional door into which holes are to be drilled for the installation of the door handle assembly or lock. A C-type clamp is included for rigidly clamping the U-shaped member to the edge of said door in the region to be drilled. A drill bushing is installed through a region of the U-shaped member in a location enabling, when the apparatus is clamped to the edge of the door, the guiding a drill for drilling a hole into the edge of the door. A plurality of side plates is provided, each of which has a plurality of drill guide apertures or bushings arranged in relative locations for guiding the drilling of holes through the door for the installation of a particular type of door handle assembly or lock.
