Abstract: A hinged spreader board of a pre-set length with shaped ends is pivoted open inside a frame to mate with the inside faces of the sides of a frame and maintain the sides apart by the length of the board while attaching the frame to a wall. Additional hinged sections of pre-set lengths allow the spreader board to be opened to various lengths to accommodate frames of different widths. The frame spreader boards fold up for storage.

Abstract: A square channel shaped template of ultra-thin rigid plastic, metal or other material has one or more mating configurations of pencil-point-size marking holes in the two opposing faces of the channel. Each configuration of marking holes matches a configuration of screw holes on a door fixture or door hardware to be mounted on a door. Each configuration of holes may be distinguished by a visible line through the marking holes of each configuration. The template straddles an edge of a door at a measured distance along the edge and fits on the edge with the door closed in a door frame for marking either one or both sides of the door with a mating configuration of marks on the door for drilling.
